Mount Kōya: The Mountain That Calls You, and the Master Who Never Stopped Meditating

A 1,200-year vow, a forbidden mausoleum, and the strange thread that runs from esoteric Buddhism to the darkness of the 20th century.

---

Maybe I should not be writing this.

Mount Kōya, in Wakayama Prefecture.

The headquarters of Shingon esoteric Buddhism, founded by Kōbō Daishi Kūkai.

A religious city of 117 temples, clustered together on a plateau 800 meters above sea level.

A place unlike any other on Earth.

In its innermost sanctuary, Okunoin, it is believed that Kūkai is still alive — at this very moment.

For 1,200 years, twice a day, every day, a meal has been carried to the man who entered eternal meditation in the year 835.

In rain.

In snow.

In typhoons.

Since the moment Kūkai entered nyūjō, this ritual has never stopped.

Not even once.

The mausoleum at Okunoin is forbidden ground. Even members of the Imperial family may not enter. Only one person is permitted inside: a single monk called the yuina. What he sees there, he must never speak of. To anyone.

Tagon muyō — not to be spoken of.

That is the seal placed upon the deepest point of Mount Kōya. And it has remained there for 1,200 years.

This is a story about that mountain.

A mountain that can only be reached by those who are called.

Prologue — “There is a mountain you cannot reach unless you are called”

Northeastern Wakayama Prefecture. A plateau 800 meters above sea level.

Surrounded by the deep mountains of the Kii Peninsula, there is a hollow in the heights where 117 temples stand clustered together. A religious city. Search the entire world, and you will not find another place like it. A whole town, sitting on top of a mountain, existing for one purpose alone:

devotion.

That is Mount Kōya.

On a map, Mount Kōya sits in an oddly inconvenient place.

Far from Nara. Far from Wakayama City. Far from Osaka. No bullet train goes there. From the nearest station, you transfer to a cable car, then take a bus that winds up the mountain. Only then do you arrive. The mountain roads are steep, and in winter, the snow closes them in.

And yet, more than 1.4 million people make their way to this mountain every year.

Why?

Because they feel they have been called.

This is not a metaphor. Ask anyone who has been to Mount Kōya, and you will hear the same things, again and again:

“Before I knew it, I was going.”

“One day, Mount Kōya would not leave my mind.”

“I suddenly kept seeing the words Mount Kōya everywhere — on TV, in magazines.”

“My schedule cleared itself, somehow.”

At the turning points of life. When the heart is worn out. When something has been lost.

That is when Mount Kōya calls.

And those who are called always arrive.

Who is doing the calling?

The answer given on the mountain is this:

Kōbō Daishi Kūkai.

March 21, 835. Four o’clock in the morning.

In the underground chamber of Okunoin on Mount Kōya, Kūkai sat in the full-lotus position, closed his eyes, and stopped speaking.

In esoteric Buddhism, this is called nyūjō.

It is not death.

It is entering eternal meditation.

Even now, 1,200 years later, on Mount Kōya, Kūkai is alive.

Twice a day, at 6:00 a.m. and 10:30 a.m., meals are carried to him. The ritual is called shōjingu — an offering made to the living body. The food is based on shōjin ryōri, traditional Buddhist vegetarian cuisine, though sometimes pasta or stew is served as well. Once a year, on the anniversary of his nyūjō, fresh robes are delivered to him.

In rain. In snow. In typhoons. Through wars. Through the pandemic.

For 1,200 years, this has never stopped. Not once.

Whether you call it faith or miracle is up to you.

But as a matter of fact, it continues.

Something changes when people go to Mount Kōya.

The reason is unclear. They simply change.

One person, walking the approach, suddenly finds they cannot stop crying.

Another, the moment they cross Gobyōbashi — the bridge to the mausoleum — says the air has changed.

Another, the moment they enter the Reihōkan museum, gets a headache and has to leave.

Another, in their room at a shukubō temple lodging at night, hears sutras being chanted from the room next door — where no one is staying.

Another returns home from Mount Kōya, and the entire stage of their life has somehow shifted.

“It’s your imagination,” some will say.

“It’s the altitude — 800 meters can affect the body,” others will say.

But no explanation truly fits.

Because this mountain is not just a tourist destination.

What this article is.

In this article, I will write about Mount Kōya in a way most guidebooks do not.

Who was Kūkai, really? What is this 1,200-year ritual of daily meals? What is the overwhelming power that fills the Reihōkan museum? Why do corporate graves line Okunoin — shaped like Yakult bottles, UCC coffee cups, rockets, and termites? And what is the strange thread that runs from the ritual tools of esoteric Buddhism to the darkness of Nazi Germany?

There is an old saying:

“Whether you believe it or not is up to you.”

But with Mount Kōya, it is the other way around.

Whether you believe it or not, those who are called will arrive.

Chapter 1 — Who Was Kūkai? — A Life Beyond Human Measure

Kōbō Daishi Kūkai.

In all of Japanese history, no one else has been deified quite like him.

The name Kōbō Daishi — “the Great Master Who Spread the Dharma” — was not his birth name. It was a posthumous title granted by Emperor Daigo in the year 921, eighty-six years after Kūkai’s death. The state, in other words, officially declared: “You were a Great Master.”

No other Buddhist monk in Japan has ever received that treatment.

But if you think of Kūkai as merely an “important monk,” you have already misunderstood him.

Kūkai broke out of the category of monk long, long ago.

---

The boy from Sanuki

He was born in 774, in the province of Sanuki — present-day Zentsūji City, Kagawa Prefecture.

His childhood name was Mao. His father, Saeki no Atai Tagimi, was a local clan chief. His mother, Tamayori Gozen, came from a respected family. His lineage was, by no means, humble.

At fifteen, Mao was summoned to the capital, Nagaoka-kyō. His maternal uncle, Atō no Ōtari, was a renowned scholar — tutor to Prince Iyo, a member of the imperial family.

Under his uncle, Mao was drilled in classical learning for three years. At eighteen, he entered the Daigaku, the state university of the time.

He was, consistently, at the top of his class.

If he had stayed on that path, his rise as a state bureaucrat would have been certain. He was on the elite track of his era.

But Mao threw it away.

He abandoned the elite official position, on his own, without hesitation.

He explained his reason later in writing:

“I wanted to find the true way to live as a human being.”

And then, he walked into the mountains.

---

Years of disappearance

From here, Mao’s “missing years” begin.

No one knows his exact movements.

What is certain is that he lived as a wandering mountain ascetic. He walked the mountains of Japan alone. He stood under waterfalls. He meditated in caves. He ate the bare minimum to stay alive.

And then, he encountered a single practice.

Kokūzō Gumonji-hō.

Without understanding this practice, you cannot understand Kūkai’s “phenomenon.” Nothing about him will make sense.

---

What is Kokūzō Gumonji-hō?

It is one of the most extreme ascetic disciplines in all of esoteric Buddhism, centered on the Bodhisattva Kokūzō.

Kokūzō, in Sanskrit, is Ākāśagarbha — “the store of wisdom and compassion as vast and limitless as space itself.”

In other words: a practice to take the universe itself into your own body.

The method is this:

You chant the mantra of Kokūzō:

Nōbō akyasha kyaraba ya on arikya maribori sowaka.

One recitation takes about three seconds.

You chant it ten thousand times a day.

Every day, for one hundred days.

For a total of one million times.

It is not enough simply to chant. You must count as you chant. If you lose count, even once, you start over.

And if you complete it — what then?

You are said to gain unlimited memory.

Anything you have seen or heard, you will never forget.
Any sutra, any text, you understand instantly and remember forever.
Any language, any branch of learning, gets stored permanently inside your mind.

The faculties of a “once-in-a-thousand-years” genius unlock.

This is not legend.

Kūkai himself wrote it down, in his own work Sangō Shiiki:

“There was a wandering monk who taught me the Kokūzō practice. The sutra said: ‘If you follow this method and chant this mantra one million times, you will be able to memorize the meaning of every sutra.’ I trusted the Buddha’s words. I climbed Mount Tairyū in Awa Province, and devoted myself to the practice at Cape Muroto in Tosa Province.”

Then he wrote, in a single line:

“The valley gave back every echo. The morning star descended, and cast its light upon me.”

The valley returned every chant he uttered, without holding back.
And the morning star — Venus — descended, and cast its light.

What does this mean?

Venus came down from the sky.

Venus flew into Mao’s open mouth.

Venus is the avatāra — the incarnation — of the Bodhisattva Kokūzō.

This is the moment of jōju — attainment.

The sign that the practice had been fulfilled.

---

A practice that borders on death

This discipline is not merely harsh.

For one hundred days, you confine yourself to a single hall and chant the same mantra, again and again, millions of times.

And the demons come.

You hallucinate.
You hear voices.
Your body refuses to move.
Or your body begins to move on its own.

“One step away from madness or death.”

That is how the esoteric tradition describes it.

And Mao, in his early twenties, came through it alive.

He completed it.

You could say his brain was rewritten at that moment.

He no longer had the memory of an ordinary human.

He no longer had the concentration of an ordinary human.

He no longer had the cognitive faculties of an ordinary human.

Everything that follows in Kūkai’s “superhuman” career stands on top of this single accomplishment.

He learned Sanskrit and Chinese in a matter of months.

He sailed to Tang China and, in just three months, was entrusted with the entire transmission of esoteric Buddhism.

While studying in China, he also took in Confucianism, Daoism, Nestorian Christianity, Zoroastrianism, and Manichaeism.

These were not the achievements of “a genius.”

These were the achievements of someone who had completed Kokūzō Gumonji-hō.

Once you understand this, everything else falls into place.

---

The crossing to Tang China

At thirty, Kūkai decided to sail to China.

He would go and seize the deepest secrets of esoteric Buddhism, himself.

This was a journey at the edge of death.

Half of all Japanese embassy ships to Tang China sank. There was no guarantee of arriving alive. No guarantee of returning alive.

And the rules required foreign students to remain in China for twenty years. Twenty years. By the time he returned to Japan, Kūkai would be fifty.

Even so, he decided to go.

In 804, at the age of thirty-one, he was formally ordained at Tōdai-ji’s Kaidan-in, and took the religious name Kūkai — meaning “Sea of Emptiness.”

That same year, he boarded an embassy ship and set sail from Naniwa Harbor.

The fleet was struck by a storm.

Of four ships, two were lost. Kūkai’s ship was blown far off course and drifted to Sekiganchin in Changxi County, Fuzhou — a place where no Japanese envoy was supposed to land.

The local officials suspected they were illegal immigrants.

Here, Kūkai’s “phenomenon” revealed itself for the first time.

In flowing Chinese — in the most refined literary style of the era — he wrote a formal petition to the officials.

The officials were stunned.

“This is not an ordinary Japanese.”

He was granted special permission to enter the capital, Chang’an.

---

Three months that changed Japan

When Kūkai arrived in Chang’an, he went straight to Qinglong Temple, where the legitimate heir of the esoteric Buddhist lineage — Master Huiguo — was waiting.

Huiguo was at the peak of Chinese esoteric Buddhism. Even the emperor revered him. He was a living Buddha. He had more than a thousand disciples, including senior monks who had trained under him for ten, twenty years.

By that time, Huiguo had already fallen ill. He knew his death was near.

And the moment Kūkai stepped into the room, Huiguo is said to have spoken these words:

“I have been waiting for you.”

Setting aside a thousand disciples, Huiguo decided to transmit all of esoteric Buddhism — everything — to the foreign monk who had just arrived.

“I will entrust the Dharma to you.”

The three initiations — Taizōkai, Kongōkai, and Ajari denbō — which normally take more than a decade to receive, Huiguo transmitted to Kūkai in only three months.

Sutras. Ritual implements. Mandalas. Mudras. Mantras.

The entirety of esoteric Buddhism.

And then, Huiguo conferred upon Kūkai the highest title of all: Henjō Kongō — “the Vajra that Illuminates All.”

A few months after the transmission was complete, Huiguo died.

As if he had stayed alive only long enough to pass everything on to Kūkai.

---

Breaking the rules, returning to Japan

Kūkai violated the twenty-year rule and returned to Japan after only two years.

By law, this carried the death penalty.

But Kūkai used the knowledge and spiritual power he had brought back from China to win the absolute trust of Emperor Saga.

In 810, a political crisis erupted — the Kusuko Incident.

Kūkai was summoned to court, where he performed the Ninnōkyō-hō, an esoteric Buddhist ritual.

The crisis subsided.

Coincidence?

The imperial court did not see it that way.

“Kūkai’s prayer stopped the war.”

From here, Kūkai’s legend accelerates.

---

A man of impossible range

In calligraphy, he is counted as one of the Sanpitsu — the Three Great Brushes. The other two are Emperor Saga and Tachibana no Hayanari. Kūkai’s calligraphy was, in other words, on the level of the emperor himself. He stands at the summit of Japanese calligraphy.

As a civil engineer, he repaired the massive Manno reservoir in Sanuki Province — a project that had defeated the imperial court for years — in only three months.

The court had labored over it for years without success. Kūkai finished it almost overnight. In China, he had studied civil engineering and hydraulics as well.

He founded Shugei Shuchi-in, Japan’s first private school, opening education to commoners. In an era when learning was the privilege of the elite, Kūkai broke that privilege open.

Legend says he composed the Iroha poem — the alphabetic verse that contains every Japanese kana exactly once.

Legend says he invented the kana writing system itself.

These attributions are disputed by scholars — but the fact that people across the centuries kept saying “Kūkai must have made it” tells you something about his strangeness.

And across Japan, the legends of Kūkai are everywhere.

The Mamushi Onsen in Itoshima, Fukuoka, was conjured up by Kūkai’s spiritual power.
Kawaba Onsen in Gunma erupted when Kūkai struck the earth with his pilgrim’s staff.
The eighty-eight temple pilgrimage circuit of Shikoku is based on the path Kūkai walked during his training.

From Hokkaidō to Okinawa: springs Kūkai caused to flow, temples Kūkai built, statues Kūkai carved, demons Kūkai subdued, bridges Kūkai built in a single night — there are countless such stories.

Even scholars cannot fully catalogue all the legends of Kūkai.

To the common people, Kūkai was never “the founder of Shingon esoteric Buddhism.”

He was the impossible figure people turned to when no human help remained.

When the rain stopped falling, call Kūkai — and the rain returned.
When plague broke out, Kūkai chanted, and the plague stopped.
When war came, Kūkai prayed, and the war subsided.

The people of his time believed this.

And, 1,200 years later, there are still people who believe it.

Because Kūkai, even now, is alive.

---

The decision

At sixty-one, Kūkai informed the imperial court: “I will not return to the capital again.”

And he secluded himself on Mount Kōya, the mountain he had opened himself.

His disciples were uneasy. Kūkai was preparing for something.

On March 15, 835, he gathered them together and spoke:

“On the twenty-first of this month, I will enter eternal meditation. I will not die.”

The disciples held their breath.

Kūkai continued:

“In 5.67 billion years, when the Bodhisattva Miroku descends into this world, I will descend with him as his attendant. Until that day, I will remain here in meditation. My body will stay in this place.”

5.67 billion years.

A span of time long enough for the universe itself to perish. Kūkai said he would wait it out in meditation.

His disciples wept.

But at four in the morning on March 21, exactly as he had foretold:

Kūkai entered the underground chamber of Okunoin. He took the full-lotus position. He formed the mudra of Dainichi Nyorai — the Cosmic Buddha. He chanted his mantra. He closed his eyes.

He stopped speaking.

His breath, too, seemed to stop.

But no one said that Kūkai had died.

The disciples enshrined his body.

Above it, they built a mausoleum.

This is nyūjō.

It is not death.

And here, the 1,200 years of Okunoin begin.

Chapter 2 — The Pine of the Three-Pronged Vajra: A Ritual Tool That Flew Through the Sky, and Two Dogs Who Showed the Way

Rewind, just a little.

This is just before Kūkai sailed back to Japan, after receiving the entire transmission of esoteric Buddhism in Tang China.

The harbor at Mingzhou — present-day Ningbo, China.

Kūkai was about to return home. But one thing had not yet been decided.

“Once I return to Japan, where should I build the seat of esoteric Buddhism?”

Where, in all of Japan, was there a sacred ground worthy of holding this teaching?

Kūkai did not know.

So he did something strange.

He drew out a ritual implement that Master Huiguo had given him: the sanko-shō — the three-pronged vajra.

---

The Weapon of Thunder

In Sanskrit, it is called vajra — the most important ritual implement in esoteric Buddhism.

It is a metal pestle. About twenty centimeters long. Both ends split into three prongs.

Originally, it was the weapon of Indra — the strongest god in ancient Indian myth, the wielder of thunder. In one legend, Indra used the vajra to shatter Vritra, the serpent-demon, into pieces.

The word vajra means “harder than a diamond.” It means “thunder itself.”

In esoteric Buddhism, this mythological Indian weapon was adopted as a ritual tool — a symbol of the enlightened mind that shatters all defilements of the heart.

Whoever holds the vajra breaks demons, deflects misfortune, and dissolves the corrupt mind.

This was the implement Kūkai now lifted, on the shore at Mingzhou.

And he hurled it.

Toward the east.

Toward Japan.

“May this come to rest on the sacred ground most suited for the spreading of the True Word.”

That was his prayer as he released the vajra into the sky.

The vajra rose, high into the air.

And it flew east.

Across the sea.

Through the clouds.

Toward the place that was waiting for it.

This is what later became known as the Hikō Sankoshō — “the Flying Three-Pronged Vajra.” The single greatest legend in the history of esoteric Buddhism.

“That cannot have happened,” modern common sense will say.

But here, let me remind you of one thing.

This is the story of a man who completed Kokūzō Gumonji-hō.

This is the story of a man who summoned the morning star into his own mouth.

For such a man — how “impossible” is it, really, to throw a vajra from China to Japan?

That, I leave to the reader.

---

Two dogs in the mountains

After returning to Japan, Kūkai began to search for the vajra he had thrown.

But Japan is wide. From Hokkaidō in the north to Okinawa in the south. Where had the vajra come down?

Then, one day, Kūkai encountered a strange figure.

The scene was somewhere in Uchi-gun, Yamato Province — present-day Gojō City, Nara Prefecture.

A hunter appeared.

A flushed, sun-darkened face. Six shaku tall — more than 180 centimeters. He wore a blue tunic. Powerfully built. A bow and arrows slung across his back.

And he had two dogs with him.

One white.

One black.

The hunter spoke to Kūkai.

“Where are you going?”

Kūkai answered honestly.

“I am searching for a place suitable for the practice of esoteric Buddhism. To tell the truth — I threw a vajra from Tang China toward Japan, and it must have landed somewhere. I am on my way to find it.”

The hunter laughed.

“I am the dog-keeper of the southern mountains. I know the place you are looking for. Let my dogs lead the way.”

He released the two dogs.

The white dog and the black dog took off running.

And then, they vanished.

“They are heading toward that mountain. Follow them.”

Kūkai followed the dogs into the mountains.

There, another figure appeared.

A woman in the form of a mountain spirit — radiant, otherworldly.

She led Kūkai deeper still.

And finally, they arrived at a plateau, high in the mountains.

It was deep within the Kii mountain range. Eight hundred meters above sea level. Cut off completely from any human settlement.

A strange hollow, ringed on all four sides by mountains.

At the center of the hollow, a single, great pine tree stood.

Kūkai looked up at it.

And he caught his breath.

Something was caught in the branches.

Something giving off the gleam of metal.

A metal pestle, with both ends split into three prongs.

It was the vajra Kūkai had thrown, three years earlier, from the harbor at Mingzhou in Tang China.

Across three years. Across the sea. Through the sky. It had come to rest in the branches of this pine.

Kūkai decided, on the spot.

“This is the place.”

This is the sacred ground from which to spread esoteric Buddhism.

This is where the seat will be.

---

The gods who guided him

Later, it would become clear that the “hunter” and the “mountain woman” who had guided Kūkai were not human.

The hunter was Kariba Myōjin — also called Kōya Myōjin — the mountain deity of the hunt.

The mountain woman was Niutsuhime, also called Niu Myōjin — an ancient goddess of the Kii mountains.

Both were the original landholding gods, worshipped in this region long before Kūkai’s time.

In other words: Kūkai was led to Mount Kōya by gods.

And the two dogs were the messengers of the gods.

Because of this legend, statues of dogs began to appear in shrines and temples associated with Kōbō Daishi all across Japan. Kūkai and dogs are inseparable.

---

The vajra still exists

That vajra — the one that hung from the branches of the pine — still exists today.

It is preserved at Kongōbu-ji on Mount Kōya, designated as an Important Cultural Property of Japan.

The actual object exists.

The legendary ritual tool that Kūkai is said to have thrown from China is still on Mount Kōya, now.

And the pine that held it is called Sankō no Matsu — “the Pine of the Three-Pronged Vajra.” It still stands today, in the Danjō Garan, the central temple complex of Mount Kōya.

There is one more curious thing about this tree.

Ordinary pine needles grow in clusters of two.

But the needles of the Sankō no Matsu grow in clusters of three.

The same number as the three prongs of the vajra.

“This is the work of the Master’s spiritual power,” the faithful say.

And it is said that if you find a fallen needle-cluster of three under this pine, fortune will come to you.

It is the Mount Kōya version of the four-leaf clover.

Carry one in your wallet, and your finances improve.
Carry one in your bag, and your travels stay safe.
Keep one as a talisman, and misfortune is turned away.

To this day, around the Sankō no Matsu in the Danjō Garan, you will find tourists with their heads bowed, searching the ground.

Families with children, searching together, absorbed.
Couples, searching side by side.
Foreign tourists, watching Japanese visitors searching for something on the ground, puzzled.

Three-needle clusters are rarely found.

But when one is found, someone cries out:

“Found one!”

And in that moment, everyone there is connected to Kūkai’s legend.

A vajra, thrown east from a Chinese shore, 1,200 years ago.

Guided by two dogs — the messengers of gods — and caught in the branches of a pine, in the mountains of Kii.

That story, in this exact moment, is connected to a single pine needle resting in a child’s palm.

This is what the air of Mount Kōya is made of.

---

The Sacred Boundary

There was one more thing Kūkai picked up when he arrived at this mountain.

The concept of kekkai: a sacred ritual boundary.

As soon as he set foot on Mount Kōya, Kūkai realized something.

This was not an ordinary mountain.

“The energy here is too strong.”

If left as it was, ascetic practitioners would not be able to endure it.

So Kūkai used the rites of esoteric Buddhism to draw a kekkai around Mount Kōya.

“For seven ri square around this mountain, let the world be sealed as sacred ground.”

Seven ri square is roughly an area twenty-eight kilometers across.

Everything within that range was severed from the outside world and consecrated as sacred ground.

The great gate at the entrance to Mount Kōya — Daimon, the Great Gate — is the symbol of this boundary. Twenty-five meters high. On either side stand the second-largest Kongō Rikishi guardian statues in all of Japan, glaring at anyone who enters.

“Beyond this gate is sacred ground. Do not bring in the defilements of the world below.”

That is what the Daimon says.

---

A universe brought down to earth

Within this boundary, Kūkai built the headquarters of Shingon esoteric Buddhism.

The Danjō Garan.

Here stood the Konpon Daitō — the Great Stupa — the Kondō main hall, the Mieidō hall of the Master’s image, and the Pine of the Three-Pronged Vajra.

It was a vast mandala, the worldview of esoteric Buddhism reproduced in physical form.

Mount Kōya is not merely a cluster of temples.

It is the cosmos of esoteric Buddhism itself, brought down to earth.

And at the center of that cosmos, Kūkai chose the site of his own grave.

Okunoin.

Here, he would, forever, withdraw.

Chapter 3 — Vajra and Hakenkreuz: When Esoteric Buddhism Crossed Paths with Nazi Germany

From here, what I am about to write may seem, to some readers, like a leap too far.

So the line must be drawn carefully.

Some parts are historical fact.

Some parts belong to the symbols people chose to believe in.

And between the two, a dangerous shadow begins to appear.

The time is 1938. Europe was moving toward war.

The place was Tibet.

Five Germans were making their way through the snow-covered Himalayas.

They were not tourists.

They were the SS expedition team, led by Ernst Schäfer, of the Nazi Schutzstaffel.

The man behind the expedition was Heinrich Himmler, head of the SS.

A close confidant of Adolf Hitler. One of the most powerful figures in Nazi Germany.

And a man deeply obsessed with the occult.

Officially, the expedition was a scientific mission — zoology, anthropology, geography. Beneath the official surface, however, ran the political, racial, and pseudo-scientific currents of Himmler’s worldview.

Why did Himmler send his men to Tibet at all?

In simplified terms, the mission was to search for the origin of the Aryan race.

---

The road from ancient India

Here, the story must briefly detour in another direction.

Rewind further. Much further.

Around 1500 BCE, Indo-Iranian-speaking peoples began moving south from the steppes of Central Asia.

Among them were groups who used the word arya — often translated as “noble.”

Some moved toward what is now Iran.

Others moved toward what is now India.

Over centuries, these traditions helped form the religious world of ancient India — the world from which Hinduism, and later Buddhism, would emerge.

And one of the highest gods worshipped in this ancient world was Indra — the god of thunder.

Indra’s weapon was the vajra.

Yes. The same three-pronged vajra that Kūkai brought back from China to Japan.

So a single line is drawn:

The vajra of Indra, an ancient Indo-Iranian thunder-god
↓
Transmitted to China, adopted as a ritual implement of esoteric Buddhism
↓
Brought by Kūkai to Mount Kōya in Japan

This is the sacred line that leads, eventually, to Mount Kōya.

But in nineteenth-century Europe, a very different story began.

---

How a sacred symbol was hijacked

The word swastika comes from the Sanskrit svastika, meaning “well-being” or “good fortune.”

Long before Nazi Germany, it appeared across many cultures — Hindu, Buddhist, Jain, and ancient European traditions among them.

When the German archaeologist Heinrich Schliemann was excavating the ruins of Troy, he found this symbol carved into the artifacts. Schliemann concluded that it was a religious mark shared by the ancient Indo-European peoples.

In twentieth-century Germany, his archaeological observation spiraled into something else entirely.

A racial mythology was constructed: that the Aryans were a supreme race, spread from ancient India to the rest of the world; that the Germanic peoples were their purest descendants; and that the swastika was the sacred symbol of that lineage.

This pseudoscience was absorbed into Nazi ideology.

The swastika became the symbol on their party flag.

To be exact, the Nazis adopted a right-facing swastika, rotated forty-five degrees, set against a red field and a white circle.

They called it the Hakenkreuz — the “hooked cross.”

In the twentieth century, the symbol was violently redefined.

The Nazis did not inherit it in a pure religious sense. They appropriated it. They turned an ancient sign of blessing into a mark of terror.

For that reason, the distinction matters.

In this chapter, swastika refers to the older sacred symbol.

Hakenkreuz refers to the Nazi emblem that turned that symbol into something else entirely.

---

Two branches, divergent

So consider this:

The Nazi Hakenkreuz and the vajra of esoteric Buddhism do not belong to the same moral world.

One was turned into a symbol of racial violence.

The other became a ritual implement for cutting through ignorance.

And yet, both were drawn — in very different ways — from the vast symbolic world of ancient India and Indo-European imagination.

That is the unsettling point.

Not sameness.

Divergence.

Two branches, grown from a shared symbolic soil, stretching in entirely different directions.

How could this have happened?

The answer lies, in part, with a single fanatic: Heinrich Himmler.

---

The fanatic at the heart of the SS

Even among the leadership of the Nazi Party, Himmler stood out for the depth of his obsession with the occult.

In Himmler’s worldview, the true homeland of the Aryans lay somewhere in Central Asia.

He imagined that, on the Tibetan plateau, traces of a pure Aryan past might still survive.

And he believed that hidden there was a spiritual key to power.

He believed one more thing.

In the occult imagination he absorbed, somewhere in the Tibetan highlands there was said to be an earthly paradise called Shambhala, or an underground kingdom called Agartha.

There slept superhuman knowledge, and a spiritual power beyond comprehension.

Whoever obtained that power, he believed, would rule the world.

This is no longer the thinking of a statesman.

It is closer to the delusion of an occultist.

But Himmler was serious.

In 1935, he founded an occult research division within the SS — the Ahnenerbe, the “Ancestral Heritage” institute.

The Ahnenerbe’s work was to “research” ancient ruins, mystical traditions, and pseudo-prehistorical theories from around the world.

The search for the Holy Grail.
Investigations into Atlantis.
Studies of runic writing.
Inquiries into Germanic mythology.
And expeditions to Tibet.

It may sound like the material of an adventure film.

But this was not fiction.

The Nazis gave these obsessions offices, budgets, and expeditions.

---

The expedition

April 1938.

The SS expedition team, led by Ernst Schäfer, arrived in Tibet.

They visited Lhasa and met with Reting Rinpoche, then regent of Tibet.

They collected skulls. They took photographs. They measured the terrain.

All of it, framed as “scientific research” — and, beneath the surface, framed as proof of the origin of the Aryan race.

---

The Buddha from Space

According to a later account, the expedition was connected to a Buddhist-looking iron statue marked with a swastika.

The story is extraordinary.

And for that reason, it must be handled carefully.

When Schäfer returned to Berlin, he is said to have shown the statue to Himmler.

It depicted Bishamonten — Vaiśravaṇa in Sanskrit — one of the Four Heavenly Kings of esoteric Buddhism.

A swastika was carved into its chest.

And the statue itself was said to be carved from a meteorite — iron that had fallen from outer space.

A Buddha that came from the sky.

For Himmler, this was more than enough.

For him, it was proof — that the origin of the Aryans lay in Tibet, that their sacred symbol had come from the cosmos itself, that the Nazi banner was the will of the universe.

The statue then disappeared from public view for decades.

In 2012, nearly seventy years after the war, a research group led by Elmar Buchner at the University of Stuttgart published a paper in Meteoritics and Planetary Science, titled “Buddha from Space.”

Their conclusion concerned the material.

The figure was carved from meteoric iron — most likely from the Chinga meteorite, which fell near the border between Siberia and Mongolia.

But that does not prove the whole legend.

It does not prove that the statue was ancient.

It does not prove that it came from Tibet.

And it does not prove that Schäfer personally brought it back for Himmler.

Some specialists have argued that the object may be a twentieth-century European creation.

So here, the line must remain clear:

The meteorite is real.
The Nazi-Tibet provenance is uncertain.
The symbolic power of the story remains.

---

Lightning, runes, and a hidden symmetry

Himmler also used another symbol for the SS.

The double “SS” insignia, drawn in the shape of two parallel lightning bolts.

This was the ancient Germanic runic letter Sigel, meaning “sun, victory, lightning.” Doubled.

Lightning.

Now, recall once more:

The original meaning of vajra, the weapon of Indra, was thunderbolt.

Lightning.

The SS turned it into an emblem of domination.

Esoteric Buddhism turned the thunderbolt into a symbol of awakening.

The contrast is difficult to ignore.

Is this coincidence?

Or did Himmler, in his fevered search across continents, somehow stray near a current that had already taken another form, far to the east, within esoteric Buddhism itself?

No one can answer that.

But this much can be said.

---

The branch he never followed

The three-pronged vajra that Kūkai brought from China to Japan, and the symbol that became the banner of Nazi Germany, belong to two utterly different moral universes — but they trace back, in their distant ancestry, to the same vast symbolic world of ancient India.

And Himmler’s expedition did reach Tibet — one of the great sacred lands of esoteric Buddhism.

But what Himmler called “spiritual power” had already, by that time, been waiting for more than 1,100 years on a mountain in Japan.

At the place where Kūkai drew his sacred boundary.

Under the earth at Okunoin.

Inside the body of Kūkai, who had entered eternal meditation.

If Himmler had known of this, perhaps he would have sent his expedition not to Tibet, but to Japan.

But he did not know.

And Nazi Germany was defeated.

Himmler took his own life shortly after the surrender.

The “Aryan spiritual power” he had searched for was, in the end, never his.

Meanwhile, at the mausoleum of Okunoin on Mount Kōya, on that same day, meals continued to be carried to Kūkai.

As if nothing at all had happened.

Through the war. Through the surrender. On the day Himmler killed himself.

For 1,200 years, without missing a single time.

---

What was, and what remains

Is this the power of esoteric Buddhism?

Or simply a chain of coincidences?

I cannot answer that for you.

Go to Mount Kōya yourself.

See it with your own eyes.

Then decide.

Those who are called will arrive.

And those who arrive will not leave empty-handed.

What Himmler searched for and never possessed —

perhaps, on the path to Okunoin,

you will realize you were already carrying it.

Chapter 4: Nyūjō — Not Death, but the Choice of Eternal Meditation

March 21, 835. 4 a.m. Mount Kōya, Okunoin.

Chapter 4: Nyūjō — Not Death, but the Choice of Eternal Meditation

March 21, 835. 4 a.m. Mount Kōya, Okunoin.

Kūkai, sixty-two years old, sat in the underground stone chamber.

The full-lotus position. Both legs crossed. Spine straight. Both hands forming the mudra of Dainichi Nyorai. This is the most fundamental, and the deepest, meditation posture in Esoteric Buddhism.

Kūkai closed his eyes. He began to chant the mantra.

“Nōmaku Sanmanda Basaradan Senda Makaroshada Sowataya Untarata Kanman.”

It may have been the mantra of Fudō Myōō. It may have been the mantra of Dainichi Nyorai. Or perhaps a deeper mantra, known only to him.

The disciples watched from outside, holding their breath.

Time passed.

At some point, one of the disciples noticed something.

Kūkai’s chanting voice could no longer be heard.

The disciple approached. Kūkai sat motionless. His breathing seemed to have stopped. But no one touched his body. No one called his name. No one checked his pulse.

Because this was not death.

This was nyūjō (入定) — not death, but entry into an eternal state of meditation.

An Entry Prepared Years in Advance

Kūkai’s nyūjō did not begin suddenly on that day. He had been preparing for it for years.

At sixty-two, he announced to the imperial court that he would not return to the capital, and he secluded himself on Mount Kōya. From that moment, the disciples sensed that something had begun.

Kūkai’s meals diminished by the day. First he stopped eating rice. Then wheat. Then beans. Then vegetables. In the end, only water.

This closely resembles mokujiki-gyō (木食行), the “tree-eating practice” associated with some sokushinbutsu traditions — the practice of self-mummified monks. A discipline to reduce body fat and water content to the absolute minimum. A preparation of the flesh, designed to bring metabolism as close to zero as possible.

Then, March 15, 835.

Kūkai gathered his disciples. His senior students lined up around their master, who had sensed that the appointed hour was approaching.

Quietly, Kūkai spoke:

“Six days from now, on the twenty-first day of the third month, at the hour of the Tiger — 4 a.m. — I will enter eternal meditation. I am not dying. Five billion six hundred and seventy million years from now, when the Bodhisattva Maitreya descends into this world, I will return as his attendant. Until then, I will continue to meditate here. My body will remain in this place.”

The disciples wept.

Kūkai continued.

“Do not grieve. I am not vanishing. I am only changing form. My consciousness, from now on, will diffuse throughout the entire universe. Whenever you need me, I will be there.”

For the next six days, Kūkai ate almost nothing. He simply chanted the name of Maitreya with his disciples:

“Namu tōrai dōshi Miroku-sonbutsu (南無当来導師弥勒尊仏).”

O Maitreya, the Teacher Who Is to Come.

And on March 21, at 4 a.m., Kūkai entered the stone chamber. He took the full-lotus posture. He formed the mudra. He chanted the mantra. He closed his eyes.

He stopped speaking.

His breathing seemed to stop as well.

But no one said that Kūkai had “died.”

What Is Nyūjō?

By dictionary definition: “to enter zenjō.” Zenjō means a deep meditative state.

But Kūkai’s nyūjō was no ordinary meditation. This is one of the deepest secret teachings of Esoteric Buddhism.

To fix the living body inside meditation itself. To slow breathing to the absolute limit, to bring metabolism close to zero. And then, to detach consciousness from the body. The detached consciousness merges with Dainichi Nyorai (大日如来), the Cosmic Buddha, the source from which all things arise. The body remains here. The consciousness diffuses throughout the entire universe.

This is the doctrine of sokushin jōbutsu (即身成仏) — “becoming a buddha in this very body.”

In ordinary Buddhism, becoming a buddha requires an unfathomable stretch of time. Specifically, it is said to require san-kō (三劫), “three kalpas.” One kalpa is roughly 4.32 billion years. Three kalpas — roughly 12.96 billion years. Longer than the age of the universe itself. That is the path of ordinary Buddhism.

Kūkai rejected this.

“No such time is needed. In this body, just as it is, in this very moment, you can become a buddha.”

This was the revolution of Esoteric Buddhism. And its ultimate form is nyūjō.

5.67 Billion Years

Another key term appears here: Miroku Bosatsu (弥勒菩薩) — the Bodhisattva Maitreya.

In Buddhism, Maitreya is the buddha who will appear after Shakyamuni and save all sentient beings. Before his death, Shakyamuni made this prophecy:

“Five billion six hundred and seventy million years after my death, the Bodhisattva Maitreya will descend into this world. He will save all those whom I could not save.”

This is Buddhism’s eschatology. Its doctrine of salvation.

5.67 billion years.

The number defies imagination. The sun is expected to expand into a red giant and swallow the earth in roughly five billion years. By the time Maitreya descends, the earth itself may no longer exist.

And still — Maitreya will come.

Kūkai declared that he would wait for that descent. “I will return with him, as his attendant.”

This is not mere wishful thinking. Within the Esoteric worldview, Kūkai has already merged with Dainichi Nyorai. Dainichi Nyorai is the universe itself. As long as the universe exists, Kūkai exists. On the timescale of the cosmos, five billion, six hundred and seventy million years is only an instant.

Kūkai is spending that “instant” beneath Okunoin.

Sokushin Jōbutsu Is Not Sokushinbutsu

There is one word often confused with sokushin jōbutsu: sokushinbutsu (即身仏).

A sokushinbutsu, in simple terms, is a mummified monk. It is a practice associated mainly with the Yudonosan faith of northern Japan, in which a monk mummifies his own body while still alive. He spends years performing mokujiki-gyō, eating only tree nuts to completely strip away his body fat. Then he drinks a special lacquer to prevent internal decay. Finally, by his own will, he enters an underground stone chamber. A single bell is placed inside. As long as the bell rings, he is alive — that is the signal.

Each day, the bell sounds. Days pass. Weeks pass.

And one day, the bell falls silent.

The disciples wait three years and three months before opening the chamber. Inside, in the meditation posture, a desiccated body remains. This is a sokushinbutsu. Even today, more than a dozen of these mummified monks are enshrined in temples in Yamagata Prefecture, and visitors can see them in person.

But this is not what Kūkai sought. Kūkai did not aim to become a mummy. Rather, sokushin jōbutsu is about reaching the state of buddhahood while alive — not about leaving a mummy behind. Whether the body decays or remains is beside the point. The point is whether consciousness has become one with Dainichi Nyorai.

What Lies Inside the Mausoleum

Still — after Kūkai entered nyūjō, what became of his body inside the Okunoin Mausoleum?

For 1,200 years, theories have been passed down.

One says he was placed inside a stone coffin.
One says soil was piled over the coffin.
One says ventilation holes were cut into it.
One says he sits exactly as he was when he entered nyūjō.
One says he has become mummy-like.
One says, in fact, he was cremated.

No one knows which is true.

Because the Okunoin Mausoleum is forbidden ground, off-limits even to the imperial family.

Only one person may enter: the yuina (維那), the monk whose role is to carry Kūkai’s meals. And the yuina is bound by an absolute rule of silence — he may never speak of what he sees inside.

For this reason, the truth of the mausoleum remains, even today, an eternal mystery.

According to historical records, it is highly likely that Kūkai’s body was cremated. Shoku Nihon Kōki (続日本後紀), the official chronicle of the period, records that his body was given to the funeral pyre. In later centuries, however, literature of the nyūjō belief begins to appear, telling of his entry into eternal meditation. These are the two historical streams of transmission.

But as devotion to Kūkai spread explosively in the centuries that followed, legend was added. Kūkai did not die. He entered eternal meditation. Inside the Okunoin Mausoleum, he is still seated, still meditating. One day, when Maitreya descends, he will open his eyes again.

Is this historical fact or legend? Scholars are divided. But here is what matters:

It does not matter which is right.

For 1,200 years, people who believed “Kūkai is still alive” have existed. And those people have carried meals to Okunoin every single day. In rain. In snow. In typhoons. Through wars. Through the pandemic. Not once, not for a single day, has it stopped.

That is the fact.

Whether Kūkai was historically cremated is no longer the question. The unbroken fact of 1,200 years of daily meals — that is what keeps Kūkai alive. The faith of the people holds him within his eternal meditation.

The Place of Waiting

The Okunoin Mausoleum. Deep inside, Kūkai is there. Seated. Eyes closed. Breath stopped. But not dead. Only waiting. For the day, five billion six hundred and seventy million years from now. For the moment Maitreya descends into this world. And Kūkai, as his attendant, will descend with him.

This is the worldview of Esoteric Buddhism. And this is the foundational structure of the place called Mount Kōya.

Okunoin is not merely a graveyard.

It is the place where Kūkai waits.

The place where Kūkai, within the timescale of the cosmos, waits for his next turn.

Think of it this way, and the strange atmosphere of Okunoin begins to make sense. Walking the path, some people suddenly cannot stop crying. Crossing the Gobyō Bridge, the air changes. Standing before the Tōrō-dō, the lantern hall, the mind goes blank.

This is not imagination.

Someone is there. Seated. Waiting. And watching you, who have come to pray.

“So, you’ve come.”

There are no words. But it reaches you.

This is nyūjō. Not death. Only something that continues, eternally.

And there is one more unbelievable fact, still continuing in Okunoin in this very moment.

The meals — carried to Kūkai.

Chapter 5: 1,200 Years of Daily Meals — Shōjingu and the Countless Stars

At Okunoin, every morning at 6 a.m., and again at 10:30 a.m. Twice a day. Every day. Meals are carried to Kūkai.

The ritual is called shōjingu (生身供). “Shōjin” means “living body.” The word stands on a premise: Kūkai still possesses a living body. And so, meals are required.

This ritual is said to have begun the day after Kūkai entered nyūjō — March 22, 835. From that day until now, for 1,200 years, it has not been missed once.

Consider what that means. 1,200 years is roughly 440,000 days. Morning and midday, twice a day — roughly 880,000 meals. Every single one, carried.

In rain. In snow. In typhoons. The day an earthquake struck. The day Kyoto burned in the Ōnin War. The day Oda Nobunaga tried to burn Mount Kōya down. The day the Meiji government destroyed countless temples in the haibutsu kishaku purge. The days when American bombers reduced Japanese cities to ash. The day the bomb fell on Hiroshima. The day the bomb fell on Nagasaki. The day Japan heard the Emperor’s voice announcing surrender. The day the great earthquake struck eastern Japan. The days Japan fell silent under the pandemic.

It did not stop.

Is this faith? Madness? Obsession? Or is Kūkai, in fact, still alive?

The Ritual

The procedure is this. At 5:30 a.m., in a building called the Gokushō (御供所), preparation of the meal begins. The cooking is done by gyōhōshi (行法師), monks with special qualifications. Their only duty is to prepare Kūkai’s meals.

Traditionally, the menu is shōjin ryōri — Buddhist vegetarian cuisine. This is a different “shōjin,” written 精進, meaning religious discipline and devotion. Rice, miso soup, simmered vegetables, pickles, tea. No animal products.

But in modern times, something interesting has happened. The menu has changed. Some days, pasta is served. Some days, stew. Some days, curry. Some days, Western food.

No one ordered this. It is the gyōhōshi’s own judgment: “Even Kūkai must want something different now and then.”

And every year on March 21, the day of his nyūjō, new robes are also brought. Even within his meditation, Kūkai is treated as one whose robes must be renewed. This too has continued for 1,200 years.

When cooking is complete, the meal is placed inside a white wooden box. At the head of the procession walks the yuina (維那), the monk whose role is to carry the meal to the mausoleum. Behind him, two monks carry the white box. The three of them set out from the Gokushō.

And just outside, they stop in front of the Ajimi Jizō (嘗試地蔵), the “Tasting Jizō.”

Here, a strange thing is done. They ask the Jizō statue to taste the meal.

“Honored Jizō, is the taste of Kūkai’s meal today acceptable?”

They wait. The Jizō says nothing. But this is not a mere formality. It is performed in earnest. Only after the Jizō has given its silent approval does the meal proceed toward the mausoleum.

The Procession

Past the Ajimi Jizō, the procession enters the path of Okunoin. On either side, cedar trees more than 700 years old rise into the sky. Beneath them stand more than 200,000 graves and memorial pagodas. The graves of warlords. Of imperial princes. Of common people. Of corporations.

Under the gaze of all of them, the three monks pass through, carrying the white wooden box.

And they reach the final bridge — the Gobyō Bridge (御廟橋).

The Gobyō Bridge is no ordinary bridge. It is made of 36 planks of wood. Counting the bridge itself as one, the total is 37. This represents the 37 deities of the Diamond Realm (Kongōkai), the central mandala of Esoteric Buddhism. On the underside of each of the 36 planks, a Sanskrit seed-letter for one of the 37 deities is inscribed. To cross the Gobyō Bridge is to walk over the 37 deities of the Esoteric universe.

Beyond the bridge lies sacred ground. From here, no photography. No food. Hats are removed. A bow is given before crossing.

And beyond the bridge, the Tōrō-dō (燈籠堂), the Hall of Lanterns, comes into view.

This Tōrō-dō is the true heart of Okunoin.

The Galaxy of Lanterns

Step inside, and the world changes.

From the ceiling to the floor, filling the entire space, lanterns hang. More than 20,000 of them. Each one holds the prayer of a worshipper. All of them sway, gently, casting light.

It looks like a galaxy.

Just as humanity looks up at the night sky and sees countless stars scattered across the dark — inside the Tōrō-dō, countless small lights float in the air. Look up. Look down. Look to either side. Light. Light. Light.

And within this galaxy, two flames have burned without going out for more than a thousand years.

The first is the Kishintō (祈親灯), the eternal lamp associated with Kishin Shōnin.

Closely connected to it is the story of the Hinnyo no Ittō (貧女の一灯) — the Single Lamp of the Poor Woman.

This lamp belongs to a story. The story of a girl named O-teru.

In the Heian period, in the province of Izumi (modern southern Osaka), a girl named O-teru lived. Abandoned by her birth parents, she was taken in by a couple named Okuyama Genzaemon and Okō, and raised as their child. At sixteen, her foster mother died of an epidemic. Despite her devoted care, her foster father soon followed.

O-teru was alone.

A traveler told her of the Tōrō-dō at Mount Kōya. “Its lights illuminate the road to the next world.”

O-teru resolved to offer a lamp at Okunoin, to pray for the peace of her foster parents in the afterlife. But she had no money.

She cut off her long black hair.

With the small sum she received for it, she bought a single, modest lamp.

She climbed Mount Kōya, and offered that lamp inside the Tōrō-dō.

The year was 1016.

And that flame is still burning today.

For more than a thousand years.

The single small flame O-teru offered now serves as the foundational light of the entire Tōrō-dō.

The second eternal flame is the Shirakawa-tō. In 1088, the retired Emperor Shirakawa offered it. The records say the emperor offered 300,000 lamps. It is known as “the Magnate’s Ten Thousand Lamps” — Chōja no Mantō (長者の万灯).

The Single Lamp of the Poor Woman. The Magnate’s Ten Thousand Lamps.

The flame a destitute girl offered with her shorn hair. And one flame among 300,000 offered by a retired emperor.

But inside the Tōrō-dō, the two flames burn at exactly the same brightness.

This is Kūkai’s teaching.

“Wealth and poverty are irrelevant. The purity of the heart is everything.”

Inside the Mausoleum

Beyond the Tōrō-dō, deeper still, stands Kūkai’s mausoleum.

The yuina and the two monks pass through the Hall of Lanterns and stand before the mausoleum. They take the meal from the white wooden box. From here, those outside can see nothing. What happens inside the mausoleum, no one knows.

The yuina, alone, places the meal before Kūkai. Then he chants. “Namu Daishi Henjō Kongō (南無大師遍照金剛).” He chants it many times. Then he presses his palms together, and withdraws.

This is the ritual of shōjingu, performed every morning at 6 a.m. When morning is done, it is performed once more at 10:30 a.m. Twice a day, every day, without pause.

Ākāśa — The Cosmic Archive

Here, something must be written — about the Tōrō-dō, about Kūkai, and about the universe itself.

The word “Akashic Records” — have you heard of it? The Akashic Records are a concept found in Western esoteric and spiritual traditions: a cosmic archive said to contain every event, memory, thought, and emotion from the beginning of existence. From the birth of the universe 13.8 billion years ago to the present moment — all of it is said to be recorded there.

The word “Akashic” comes from the Sanskrit ākāśa — space, sky, ether. In spiritual language, it points toward the vast open field sometimes imagined as the void.

And in his youth, Kūkai completed a discipline at the risk of his life. As written in Chapter 1, it was the Kokūzō Gumonji-hō (虚空蔵求聞持法). “Kokūzō” comes from the Sanskrit Ākāśagarbha. The bodhisattva who holds the void — Ākāśa — within himself.

Here, the lines connect.

Akashic Records = Ākāśa = the Void = Kokūzō Bosatsu

The discipline Kūkai completed in his youth was, perhaps, the act of installing within himself the capacity to access all the information of the universe.

Think of it that way, and many things make sense. His superhuman memory. His ability to master any language within months. The moment Master Huiguo in Tang China saw him and said, “I have been waiting for you.” All of it.

From his youth, Kūkai was already connected to the Akashic Records.

And through nyūjō, his consciousness was completely separated from his body and merged with the source of the universe. Now, within the mausoleum, in the full-lotus posture, Kūkai is connected to all the information of the universe.

Okunoin is not merely a graveyard.

It is the gateway to the Akashic Records.

The 20,000 lanterns of the Tōrō-dō are not a metaphor for the stars of a galaxy. They are the universe itself, made visible. And Kūkai sits at the center of that galaxy. Seated, until 5.67 billion years from now, in conversation with the cosmos.

There is a legend that the yuina, inside the mausoleum, sometimes hears the voice of Kūkai chanting a mantra. It is not that Kūkai is saying, “So, you’ve come.” It is that, through Kūkai, the universe itself is speaking.

The True Meaning of Shōjingu

This is the true meaning of shōjingu.

The meal carried twice a day for 1,200 years is not merely a meal. It is a ritual by which humanity, every single day, confirms its connection to the cosmos.

The mausoleum of Okunoin is the sole window through which humanity connects to the universe.

And the 20,000 lanterns of the Tōrō-dō shine around that window, like countless stars.

Tomorrow morning, at 6 a.m. At Okunoin, once again, the meal will be carried to Kūkai. While you are reading this. While you are sleeping. While you are thinking about something else entirely.

At Okunoin, the ritual continues. For 1,200 years, without pause. And today, again, Kūkai receives his meal.

And today, again, through Okunoin, humanity is connected to the universe.

Chapter 6: Kūkai at 137 — The Day Kangen Opened the Mausoleum

Time passes. Kūkai entered nyūjō on March 21, 835. And time passed.

By the early 900s of the Heian period, the world had changed. The disciples who had known Kūkai personally were all gone. The second and third generations of monks, who had inherited his teaching, now kept watch over Mount Kōya. Kūkai’s mausoleum remained beneath Okunoin, unchanged. The shōjingu was still carried out, every day.

But voices had begun to whisper. “Is Kūkai really still alive?” “Surely, by now, only bones remain?”

Then, in the year 921, Emperor Daigo decided to bestow upon Kūkai the posthumous title of Kōbō Daishi (弘法大師) — “the Great Master Who Spread the Dharma Widely.” This was a historic event: for the first time, the state was officially recognizing Kūkai as a holy master of the highest order.

(Some traditions place this opening about seventy-odd years after Kūkai’s nyūjō, making his age 137. This chapter follows that tradition in its title. The 921 chronology, however, gives an ordinary calculation of 148 years.)

And so a ceremony became necessary. The title bestowed by the emperor, and new ceremonial robes, had to be delivered to Kūkai himself. To do that, someone had to enter the mausoleum.

The mausoleum, sealed since the day of his nyūjō, had to be opened.

This was the first gobyō kaihi (御廟開扉) — the first opening of the mausoleum — in the eighty-six years since Kūkai entered eternal meditation.

The Man Sent to Open It

The man entrusted with this enormous duty was Kangen (観賢), then the highest-ranking monk on Mount Kōya. Kangen belonged to a later generation in Kūkai’s spiritual lineage. He was himself an accomplished Esoteric master, and a man trusted deeply by the imperial court.

But Kangen was afraid.

To open the mausoleum. To set foot in the holy of holies, where Kūkai sleeps.

What if, inside, there were only the remains of bones, or the ruins of a mummified body? What if Kūkai turned out to be nothing more than “a dead monk from long ago”? The legend believed for generations — Kūkai is still alive — would collapse in that instant. What would become of the people’s faith? What would become of Mount Kōya?

Kangen must have understood what was at stake. If only bones waited inside, the faith of Mount Kōya itself might collapse. But the command had come from the emperor. The mausoleum had to be opened.

Inside the Mausoleum

Tradition holds that on that day, Kangen performed a special purification, dressed in pure white robes, and set out for Okunoin with his disciple Junyū (淳祐). Standing before the mausoleum, Kangen quietly opened the doors. And stepped inside.

Inside, it was dark. Only the faintest light slipped in from outside. After a while, his eyes adjusted to the darkness. And then, he saw.

In the depths of the mausoleum, a man was seated.

In the full-lotus posture. Both hands forming a mudra. Eyes closed. Simply, sitting.

It was Kūkai.

In exactly the same posture he had taken eighty-six years before, on the day he entered nyūjō, Kūkai was sitting there. His body had not decayed. He had not become a mummy. He was sitting as though alive.

And that was not all Kangen saw.

Kūkai’s hair and beard had grown long. Past his shoulders. Past his chest. Long enough to reach the floor.

The hair of the dead does not grow. But Kūkai’s hair had been growing.

What did this mean?

Kūkai was not dead. Within nyūjō, his body was still carrying out the bare minimum of life. Breath, slowed to its absolute limit. Metabolism, brought as close to zero as possible. But not all the way to zero. The proof was there — in the hair and beard, still slowly growing.

Kangen, it is said, wept on the spot.

“The Master is alive.”

“Grandfather — it has been so long.”

Kangen addressed Kūkai as if he were a living relative. With trembling hands, he cut Kūkai’s long hair and beard. He changed his robes. And he delivered the title bestowed by Emperor Daigo:

“Grandfather, His Majesty has bestowed upon you a new name. From this day forward, you will be called Kōbō Daishi.”

Kūkai, of course, said nothing in reply. But Kangen could feel it, with certainty. That Kūkai was listening.

Slowly, Kangen stepped back, and withdrew from the mausoleum. He closed the doors. To those who had been waiting outside, Kangen said almost nothing. Only this:

“The Master was alive.”

He spoke no further. Of what he had seen inside, he told no one, ever again.

The Rule of Silence

It was here, with Kangen, that the rule was established: what is seen inside the mausoleum is not to be spoken of.

Why?

Because if it were spoken of, people would want to go and confirm it for themselves. But Kūkai’s meditation must not be disturbed. Within the mausoleum, Kūkai is connected to the universe. That connection must not be severed by worldly curiosity.

And so — what is seen, is not spoken.

This was the rule Kangen entrusted to all future yuina.

The Body That Should Not Exist

Stop here, and consider one more thing. Kūkai entered nyūjō at the age of sixty-two. Eighty-six years later, Kangen opened the mausoleum. Which means — the body Kangen saw was, by ordinary calculation, that of a man one hundred forty-eight years old.

A man far past one hundred. Hair and beard still growing. Sitting in the full-lotus posture.

This is no longer human.

And yet Kūkai, undeniably, was there.

The story of Kangen became, from that point on, the fundamental “proof” for Mount Kōya. Kūkai is, in fact, alive. This was not legend. The highest-ranking monk of his day had seen it with his own eyes. And what he had seen, he never spoke of for the rest of his life. But the look on his face as he came out of the mausoleum. The tears, said to have been wept. And the one line he gave them:

“The Master was alive.”

That was enough.

The people were convinced. Within the mausoleum at Okunoin, Kūkai still lives.

And from Kangen onward, the mausoleum was sealed forever. Only the yuina is permitted to enter the antechamber, every day. But the innermost place, where Kūkai sits — no one may enter. Not the imperial family. Not the highest-ranking monk. Only Kūkai is there.

What the Modern World Says

The story of the ever-growing hair and beard has been passed down to the present.

In modern times, rationalist researchers have tried to dismiss it as legend. The hair of the dead cannot grow. This is something later folk belief invented.

But there is something worth noting: a known postmortem phenomenon can make hair appear to grow after death. The hair itself does not grow. Rather, as the skin dries and retracts, more of the hair shaft becomes exposed, making it appear longer.

In other words, what Kangen saw was, in fact, a visual reality. He interpreted it as Kūkai is alive.

A rationalist may smile. But consider this, once again.

For that visual impression to remain possible after eighty-six years, Kūkai’s body would still have had to retain a recognizable human form. An ordinary corpse, after eighty-six years, would be reduced to bones. But Kūkai’s body, eighty-six years later, still held the form in which Kangen could recognize a “man seated.”

This was not merely ordinary mummification. A body left to decay in the usual way would not remain so clearly recognizable, seated in full lotus, after eighty-six years.

Something, for eighty-six years, was holding Kūkai’s body in the full-lotus posture.

That “something” is nyūjō. Consciousness, continuing to command the body to maintain the minimum activity of life. Breath, appearing to have stopped — but not at zero. Metabolism, brought close to zero — but not at zero. And the hair, slowly, still growing.

This is the true form of sokushin jōbutsu. The space between “alive” and “dead.” The transitional state in which a human being moves beyond the body and becomes the universe itself.

Kangen witnessed it.

The Hair That May Still Be Growing

And to this day, in that same state, within the mausoleum at Okunoin, Kūkai is seated.

Is his hair still growing? No one knows. Even the yuina is not permitted into the innermost chamber.

But imagine it, just for a moment. Twelve hundred years on, perhaps Kūkai’s hair and beard now cover the floor of the mausoleum, creep along its walls, and reach toward the ceiling. And Kūkai, veiled in that hair, is still seated. Eyes closed. Mudra formed. Connected to the universe. Waiting for the day Maitreya descends, five billion six hundred and seventy million years from now.

Chapter 7: Okunoin Is the Akashic Records

Okunoin is the Akashic Records.

This was touched on briefly in Chapter 5. Here, the line will be drawn in full.

First — what are the Akashic Records?

In simple terms: a cosmic-scale library that records every being, every event, and every piece of information since the birth of the universe. In modern spiritual language, it is often described as “the cosmic library” or “the universal internet.”

Every event since the birth of the universe 13.8 billion years ago. Every memory of every soul. Every emotion. Every piece of knowledge. All of it, recorded there. And not only the past. The events of the present, too, are recorded in real time. Even the possibilities of what may come in the future are contained within it. Within the Akashic Records, there is no such thing as missing data.

And only a handful of human beings, throughout history, have ever been able to access it. Figures such as Edgar Cayce, Rudolf Steiner, and Emanuel Swedenborg are often spoken of as people who touched this hidden field of knowledge.

But far earlier, in the East, there was already someone who had systematized the method of connecting to it.

Kōbō Daishi Kūkai.

Akashic Records = Kokūzō

The word “Akashic” comes from the Sanskrit ākāśa. It means space, ether, or the vast open field.

And the greatest discipline Kūkai completed in his youth was the Kokūzō Gumonji-hō (虚空蔵求聞持法). Kokūzō is the Japanese name for Ākāśagarbha, the bodhisattva whose very name means “Womb of Space” or “Treasury of the Boundless Sky.”

Let it be written plainly here: the Akashic Records and Kokūzō point toward the same spiritual field. They are not merely similar in mood. They share the same Sanskrit root: ākāśa.

What the late-nineteenth-century Western mystical tradition came to call “the Akashic Records” had, in the East, an older and deeper counterpart in Kokūzō. And Kūkai, in his early twenties, had already completed a discipline for approaching that field.

Recite the mantra of Kokūzō Bosatsu one million times. Ten thousand times a day, for one hundred days. Somewhere along that journey, the morning star — Venus — flies into the practitioner’s mouth. That was the sign of completion. Kūkai had connected himself to the root field of universal knowledge.

This is why his memory was superhuman. Why he could master foreign languages within months. Why Master Huiguo in Tang China, the moment he saw Kūkai, said, “I have been waiting for you.” Kūkai already stood in a place beyond ordinary human perception.

And from there, the rest of Kūkai’s life unfolded as it is known. Calligraphy, civil engineering, education, diplomacy, religion — in every field, he left achievements that mark human history. At sixty-one, he secluded himself on Mount Kōya. At sixty-two, he entered nyūjō.

What is nyūjō? It is the act of entering eternal meditation while still in the living body, and allowing consciousness to merge with the source of the universe.

In other words: Kūkai left his consciousness permanently connected to the Akashic Records, and left his body in Okunoin. And inside the mausoleum, he is seated. Even now, he is seated. For 1,200 years, he has been seated.

Which means — what is the mausoleum of Okunoin?

The Gateway

It is the gateway to the Akashic Records.

It is the physical portal, in this world, to the cosmic library. The greatest human gateway in history is inside the mausoleum, eternally holding that door open.

Listen to the accounts of those who have visited Okunoin.

“As I was walking the path, suddenly, everything from my past came back to me, all at once.”

“The moment I crossed Gobyō Bridge, I felt I had known something from before I was born.”

“Inside the Tōrō-dō, it was not so much that something was looking at me — it was that something was looking over all of me, taking me in completely.”

“After returning from Okunoin, the choices in my life suddenly became clear.”

“I understood my mission.”

“Things I had agonized over for years suddenly stopped mattering.”

“Someone appeared in my dream and gave me a message.”

Accounts like these appear again and again in stories told by visitors to Okunoin. So many people. So many similar experiences.

What Himmler Could Not Find

And Himmler, as written in Chapter 3, sent expeditions to Tibet, desperately searching for “the spiritual power of the Aryans.” He looked for Shambhala in the Himalayan mountains. He looked for Agartha. He looked for a subterranean kingdom.

He did not find it.

Why? Because he was looking in the wrong place. The “point of connection to the universe” he was searching for was not in Tibet. It already existed in Japan — in Wakayama, on Mount Kōya, beneath Okunoin. It had been opened by Kūkai, eleven hundred years before.

He did not know this. And perhaps it is better that he never did.

What Google Cannot Search

And now, you. Living in this present age. With a smartphone in your hand. Able, through Google, to access information from around the world in an instant.

But what Google can search is only the knowledge humanity has written down in text.

The 13.8 billion years of cosmic memory. The past, the present, the future of every soul. What your own soul experienced before you were born. Why you were born into this era, this country, this family. What your true mission is.

None of that is searchable on Google.

But at Okunoin — it is.

Countless people visit Mount Kōya every year. Whether they can explain it or not, many carry something back. Not necessarily a clear “answer.” But they feel a “direction.” They come to understand “what they are alive for.”

This is because Kūkai, from within the mausoleum, is turning the pages of the cosmic library for them. The answer to your question is here. Kūkai conveys this to the worshipper without words. The worshipper receives that “answer” without fully understanding it themselves, and goes home. And some time later, suddenly, they realize: ah — that thing I felt at Okunoin — this was what it was about.

This is the true function of Okunoin.

It is not merely a cemetery. It is not merely a “power spot.” It is not merely a religious site.

It is the one permanent sacred interface through which humanity connects to the universe. Kūkai offered his own body as the living core of that interface. For 1,200 years. And from here onward, for five billion six hundred and seventy million years.

Being Called

One more thing must be written.

Not everyone can access the Akashic Records. Throughout history, only a handful of human beings have ever connected to them. But there is a way to access them.

It is being called.

When the Akashic Records themselves judge that “this person should receive information,” the human being is called to Okunoin. And the one who is called, without fail, arrives.

The words in the prologue — there is a mountain you cannot reach unless it calls you — this is their true meaning. The one calling is not Kūkai. Through Kūkai, the universe itself is calling.

The fact that you are reading these words, right now, may mean that you, too, have already been called.

Chapter 8: Reihōkan — A Place Where the Power Is Too Strong to Stay

Mount Kōya has Okunoin, directly connected to the universe. It has the Tōrō-dō, which holds a flame that has not gone out for 1,200 years. It has the pine tree where the sankosho Kūkai threw from China came to rest.

And there is one more place. A place more accurately described as somewhere you endure than somewhere you visit.

The Reihōkan (霊宝館).

The Reihōkan stands just beside the Danjō Garan, at the center of Mount Kōya. Opened in 1921, it is one of Japan’s oldest wooden museum buildings. The 117 temples of Mount Kōya gather here the Buddhist statues, paintings, calligraphy, and craftworks they have preserved across 1,200 years.

The scale defies the imagination.

National Treasures: 21. Important Cultural Properties: 148. Wakayama Prefecture–designated cultural properties: 17. Important Art Objects: 2. And including uncategorized items, the holdings number roughly 100,000.

Within the walls of the Reihōkan, 1,200 years of Mount Kōya’s weight is condensed into a single building.

A Rule Felt, Not Read

The Reihōkan has a particular rule: no photography inside.

This is partly for the protection of cultural properties. But it is not only that.

Those who enter understand without being told. Here, photographs must not be taken. The urge to photograph does not arise. One feels: nothing must be taken from this place.

That is the kind of place it is.

The Four Heavenly Kings

The core of the Reihōkan’s collection is its Buddhist statuary. And among them, the works that emanate the strongest presence are the standing statues of the Shitennō (四天王), the Four Heavenly Kings, attributed to the Kamakura-period master sculptor Kaikei.

The Four Heavenly Kings are: Jikokuten (Guardian of the East), Zōchōten (South), Kōmokuten (West), and Tamonten (North). In the Indian Buddhist cosmos, they are the retainers of Indra (Taishakuten), the supreme deity who dwells atop the cosmic mountain Mount Sumeru. They guard the four gates of Sumeru.

The Four Heavenly Kings carved by Kaikei are no ordinary guardian figures.

The muscles are too real.

The veins stand out.

The thighs, the arms, the shoulders — all of them strain like the body of a living human being.

Beneath their feet, they trample jaki (邪鬼).

The jaki are beings in which human delusion and malevolent spirits have fused into one. The Four Heavenly Kings crush them underfoot, holding them down so they cannot escape.

Stand before the statues, and the air changes.

Visitors have been known to murmur:

“Just standing in front of the work, my spine straightens on its own.”

“The musculature is so real, the statue feels as though it is about to move.”

“For a moment, I felt our eyes meet.”

And there are other voices too.

“I cannot stay here long.”

“I’m starting to feel ill.”

“My head is hurting.”

“My chest feels tight.”

“I need to get outside, quickly.”

Some spiritually sensitive visitors, after visiting the Reihōkan, have written:

“The vibrational frequency here is too high. Even one trained in these things cannot stay long.”

“Even one trained in these things can feel fear in this place.”

Why the Power Is Too Strong

Here, something important must be written.

The statues of the Reihōkan are not frightening.

The statues do not attack people. They do not harm anyone.

But the energy that hangs in the air around them is strong. Too strong.

The body of an ordinary human being is not built to withstand it.

It is like this:

A 100-watt lightbulb can be approached by anyone.

But no one can stand close to the sun.

The force is simply too great.

The presence inside the Reihōkan is closer to the sun than to the lamp.

The “prayer” and “spiritual force” poured into these works have accumulated across 800 years, 900 years, 1,000 years. All of that, condensed inside glass cases.

Some people cannot bear that energy. Their bodies refuse it. Headache. Nausea. Dizziness. A pounding heart. This is not “imagination.”

The attendants at the Reihōkan entrance, after long years of service, begin to recognize it, they say.

“This person will not be able to stay long.”

“This one will be back outside in a few minutes.”

And the opposite:

“This person will stay for hours.”

“This one has been gazing at the same piece for a long time now.”

People react to the Reihōkan in completely different ways.

It is a difference in their spiritual sensitivity.

The Blood Mandala

And among all the works in the Reihōkan, one piece emits the most intense energy of all.

The Ryōkai Mandara-zu, known as the Chi Mandara (血曼荼羅) — the Blood Mandala. A vast mandala painted on silk.

The name is no exaggeration. According to temple tradition, Taira no Kiyomori, in the late Heian period, drew blood from his own head for esoteric Buddhist practice, and had that blood mixed into the pigment used in the mandala.

A mandala of the esoteric universe — with Kiyomori’s own blood worked into the pigment.

Human blood, mixed into the pigment of a sacred image.

Can a human being make such a thing?

The work itself is in the Reihōkan.

Its size defies belief. When unfurled and displayed, it covers an entire wall.

Stand before it, and you freeze.

“That is Taira no Kiyomori’s blood, mixed into these colors.”

“More than 800 years old, his blood is here in front of me.”

“And here, a mandala bears that blood within its colors.”

There are accounts of visitors, standing before the Blood Mandala, suddenly unable to stop weeping.

Accounts of visitors who, before the Blood Mandala, experienced something like a flashback of a past life.

Accounts of visitors who, before the Blood Mandala, could no longer stand and had to sit down on the floor.

And accounts of visitors whose headaches continued for some time after leaving the Reihōkan.

This is not merely a museum.

This is a spiritual storehouse, preserving 1,200 years of prayer, blood, and spiritual force.

Inside the Reihōkan, you must endure that weight.

A Place That Chooses Its Visitors

But here, one more thing must be written.

The Reihōkan is not a frightening place.

It is a powerful place.

And those who can withstand that power can have, here, an experience that changes their lives.

There are those who, after seeing the Blood Mandala, understood their life’s mission.

There are those who, after seeing Kaikei’s Four Heavenly Kings, made on the spot a decision they had been struggling with for years.

There are those who, after seeing Kūkai’s own handwritten Sangō Shiiki (三教指帰) — Kūkai’s early work comparing Confucianism, Daoism, and Buddhism — felt something inside themselves shift, struck by the force of the brush, as if Kūkai had written it in a single unbroken motion.

The Reihōkan chooses its visitors.

There are people who can stay, and people who cannot.

Both are correct.

Those who cannot stay long are simply more sensitive.

Those who can stay long are able to resonate with the energy of the place.

Both experiences can be had only at the Reihōkan.

How to Walk Mount Kōya

One piece of practical advice, before closing this chapter.

If you visit the Reihōkan, go before Okunoin.

In the Reihōkan, let 1,200 years of Mount Kōya’s weight enter your body.

Then make your way to Okunoin.

There, the presence of Kūkai will appear to you completely differently than it would have otherwise.

The Four Heavenly Kings of Kaikei, seen in the Reihōkan.

The Blood Mandala.

Kūkai’s own handwritten scroll.

All of them belong to the spiritual current that begins with Kūkai and returns to Okunoin.

Walk through that current with your body first, and then stand before the mausoleum.

By then, you are no longer a mere tourist.

You face Kūkai as one who has taken on the weight of 1,200 years.

And perhaps, at that moment, you will hear it.

“So, you have carried the weight here.”

The voice of Kūkai.

But — if you start to feel unwell in the Reihōkan, do not push yourself.

That is proof that you have already connected, fully, to its energy. Step outside, just for a moment, and breathe.

Around the Reihōkan, rhododendrons, fresh spring leaves, and autumn foliage bloom in their seasons.

Breathe deeply in that nature.

That alone is enough to settle the energy you received inside the Reihōkan into your body.

Then turn toward Okunoin.

The Reihōkan is Mount Kōya’s threshold chamber.

Here, the heart and body are made ready. Then one goes to meet Kūkai.

This may be the deepest way to walk Mount Kōya.

Chapter 9: Those Who Were Called — Unbelievable Stories from Mount Kōya

Those who go to Mount Kōya carry something back.

It is not a souvenir. It is an experience.

What follows are stories — gathered from accounts scattered across the internet — of what has actually happened to people at Okunoin, the Tōrō-dō, the mausoleum, and the shukubō (temple lodgings).

All of them are different people, at different times, in different places. If they share anything in common, it is just one thing: the person felt they had been called to Mount Kōya.

One: The Voice of the Father

A woman in her thirties, working at a company in Tokyo.

She had no particular complaints about her life, she says. Work was going well. Relationships were going well. Her family was healthy. But one day, suddenly, the word “Kōyasan” dropped into her mind.

At first, she ignored it. She had no idea why, all of a sudden, Mount Kōya.

But from that day on, strange things began to happen.

A television she happened to turn on was running a special program about Mount Kōya. She walked into a bookstore, and a stack of Mount Kōya books was on display at the entrance. At lunch, the person at the next table was telling a friend, “Last week, I went to Mount Kōya, you know…”

“I am being called to Mount Kōya.”

That was her conclusion. Three weeks later, she took some time off and made the trip alone.

She had been walking the path of Okunoin for about five hundred meters.

Suddenly, she could not stop crying.

She did not know why. She was not sad. She was not happy. The tears simply kept coming, one after another.

On either side of the path, cedar trees more than 700 years old rose into the sky. On the ground, the 200,000 graves and memorial pagodas. She walked on through them, crying.

By the time she crossed Gobyō Bridge, the tears had stopped. In their place, her mind had become strangely, deeply quiet.

And the moment she entered the Tōrō-dō, she heard it.

“Thank you.”

Not a voice. But she heard it, clearly, inside her head.

She did not know whose it was. But she knew it was the voice of her father, who had died.

Her father had passed three years before. While he was alive, she had never been able to say “thank you” to him. That had stayed, lodged somewhere inside her, ever since.

There, on the spot, she wept openly.

After returning to Tokyo, her life changed, she writes.

It is hard to explain what changed. But she writes this:

“I was able, finally, to say goodbye to my father. Until then, my life had been stopped. Now, at last, I am moving forward again.”

Two: The Current

A man in his forties, living in the Kansai region.

He had always been sensitive to invisible things. He was not a medium or a professional psychic, but since childhood, he had often seen or felt things others could not.

This man climbed Mount Kōya for the first time.

As he walked the path of Okunoin, something began to change in his body.

“There’s a current running through me.”

From the crown of his head to the soles of his feet, a tingling like an electrical current ran continuously. It did not hurt. If anything, it felt good. Like a low-frequency therapy device held against his entire body.

He crossed Gobyō Bridge and stood before the Tōrō-dō, and the current reached its peak.

Something descended onto the top of his head. That was how he felt it.

It was not Kūkai. Not something as vast as Kūkai. But something — a concentration of energy — had settled on top of his head.

For about twenty minutes, he could not move from in front of the Tōrō-dō.

After returning home, a certain change began in his life.

The blog he had been writing as a side project, almost as a hobby, suddenly began to be read. It began appearing at the top of search results. Within a month, the income from it had surpassed his salary from his main job.

Six months later, he quit his company and went independent.

“That moment at the Tōrō-dō — something gave my life a green light.”

That is what he writes.

Three: The Word “Daijōbu”

A woman in her fifties, from Kyushu.

She had been diagnosed with cancer. Stage III. Surgery had been recommended.

But something held her back.

Before I have the surgery, there is a place I need to go. That is what she felt.

That place was Mount Kōya.

She had never been. She had no idea why she wanted to go. But she felt — I have to go.

She and her husband made the climb together.

Before the mausoleum at Okunoin, she stood with her hands pressed together for a long time and prayed to O-Daishi-sama — the intimate and reverential name by which devotees address Kōbō Daishi Kūkai.

“O-Daishi-sama, I do not want to die yet. I want to live a little longer. I still want time with my family.”

That was her plea, spoken in her heart.

At that moment, something resonated inside her head.

“It is all right. You still have life ahead of you.”

Not a voice. But it reached her clearly.

There, on the spot, she wept openly. And there, on the spot, she decided.

“I am going to live.”

She had the surgery afterward. Her recovery was unusually good. Five years later, she was told there was no sign of recurrence.

“If Mount Kōya had not called me, I would have walked into the operating room in despair. If I had not heard that ‘It is all right,’ my body might not have recovered.”

That is how she looks back on it.

Four: The Chanting in the Night

This story takes place in a shukubō.

A shukubō is a temple lodging. Mount Kōya has more than fifty of them. Tourists can stay overnight. Vegetarian shōjin ryōri meals at evening and morning. Morning prayer services. Sutra copying.

A man in his twenties stayed at a shukubō for the first time.

He ate dinner. Bathed. Returned to his room. Late at night, he woke.

He could hear something.

A sutra was being chanted, low and slow.

A male voice, reciting.

At first, he thought a guest in the next room was chanting something. But the voice was too close. It was not coming from the next room. It was coming from somewhere right beside him.

He looked around his room.

No one was there.

But the chanting continued.

Ten minutes. Twenty. Thirty. The chanting did not stop.

He was not afraid. He did not know why, but he felt at ease. Some instinct told him this was not a presence that meant him harm.

After a while, he fell asleep again.

In the morning, he told a monk at the shukubō what had happened.

The monk smiled. “It’s not so unusual. One of the disciples of O-Daishi-sama is probably continuing his prayers through the night.”

“A disciple — you mean someone living?”

“No. Someone who passed away long ago. But just like O-Daishi-sama, he continues to chant sutras within his meditation.”

The young man could not speak.

But it was true that the chanting he had heard was not in modern Japanese. The pronunciation, the cadence — it was strange, like something from the Heian period.

“Did I hear someone’s prayer service from a thousand years ago?”

That is what he writes.

Five: What Came Home in the Photograph

This story is well known, even among the strange ones.

A woman went to Mount Kōya with her family and prayed at Okunoin. She walked the path normally. Crossed Gobyō Bridge. Pressed her hands together at the Tōrō-dō. Properly put her smartphone away in the no-photography zones.

Nothing seemed unusual.

But back home, when she went through the photographs she had taken —

In one photograph, above her own head, a white, mist-like glow was captured in the frame.

No one else in her family showed it. Only above her head.

At least, that is what she writes: it was not backlight, and it was not a smudge on the lens.

And after that, a change began in her.

“My intuition started proving right.”

Decisions at work. Decisions in relationships. Decisions in everyday purchases. Every hunch she followed seemed to lead her in the right direction.

And she began to be drawn — for the first time in her life — toward “prayer” and “meditation,” subjects she had never been interested in.

“Something came back with me, on top of my head.”

That is what she writes.

Six: The Grave That Stopped Her

This story is from another woman.

She had this experience at Okunoin.

As she was walking the path, suddenly, her feet stopped.

It was not that something pulled her. But her feet would not move.

Standing still, she looked, and right in front of her was a small grave.

A name she did not know. She had no idea whose grave it was.

But she could not move from that spot.

And inside her head, she heard:

“Thank you.”

The voice of a man she did not know.

She pressed her hands together at the grave, and prayed for a while.

She had not come to ask for anything. She simply put her hands together, as if responding to that voice.

She stood like that for perhaps five minutes.

And then, suddenly, her feet could move again.

She walked the rest of the path to its end.

After returning to Tokyo, she had a dream.

In the dream, a man she did not know appeared.

“Thank you, for the other day. I had been waiting there for a long time, unnoticed by anyone. I was glad that you stopped. Because of you, I can finally go.”

The man said this, and disappeared.

She has not had that dream again since.

“Whose grave was it? Why did I stop there? Even now, I don’t know. But I think something — through me — was set free.”

That is what she writes.

What They Have in Common

These are all accounts reported by people who went to Okunoin, found scattered across the internet.

Search, and you can find more.

Hundreds. Thousands. Perhaps tens of thousands.

And they all share something in common.

Before they went, and after they went — their lives changed.

Clearly. Unmistakably.

And the people who changed say things like this.

“I was called, and I went.”

“And I came home with an answer.”

What the “answer” was, even they often cannot say clearly. But looking back, something had happened at Okunoin.

Whether it was Kūkai, or the universe, or one’s own soul, no one knows.

But something, undeniably, happened.

And perhaps — you, who are reading this now, this far —

Perhaps you, too, have already been called.

Those who are called eventually notice it.

And the moment they do, they go — without hesitation — to Mount Kōya.

Chapter 10: The Forest of Corporate Graves — Coffee, Yakult, Rockets, and Termites

The path of Okunoin is no ordinary path.

More than 200,000 graves and memorial pagodas line it. The graves of warlords are among them. As Chapter 11 will discuss: Oda Nobunaga, Takeda Shingen, Tokugawa Ieyasu, Uesugi Kenshin, Date Masamune, Akechi Mitsuhide. Many of the most prominent figures in Japanese history are gathered here.

But as you walk the path, another kind of grave — completely unlike the graves of warlords — comes into view.

The kigyō-baka (企業墓) — a corporate memorial grave.

Okunoin is said to hold somewhere between 100 and 140 of them.

Imagine it for a moment. A grave belonging to a company. The company has not died. The company is still in business, operating as we speak. And yet, in the company’s name, a grave has been built.

Why?

Because the company built it to honor the souls of its employees, its business partners, its customers — and the souls of its products themselves.

The souls of products — or, more precisely, the souls of the things that have served human life. You may wonder what that means. But the Japanese have, since ancient times, believed that spirits dwell in things. There are memorial rites for worn-out needles, for dolls, and for knives and blades. Even objects have souls. So when you have been served by an object for many years and the time comes to discard it, you offer thanks and a proper farewell.

The Japanese do this at the corporate scale, too.

And the central sanctuary of this practice is the path of Okunoin.

One: The Coffee Cup Grave (UCC Ueshima Coffee)

Walk the path, and you will see, rising into view, a massive coffee cup and saucer.

On a stately saucer, a round, generous coffee cup sits. Inside, red stone has even been used to render the color of coffee itself. The level of detail is extraordinary.

This is the corporate grave of UCC Ueshima Coffee Co., Ltd.

The message is clear. It is as if the grave were saying: We honor here the souls of every coffee bean that served us, and the souls of every customer we have served.

We drink coffee every day. A single cup uses roughly a hundred coffee beans. An immense volume of coffee is consumed across the world each year. Behind that volume stand an unimaginable number of coffee cherries, the farmers who raised them, the workers who carried them, the craftspeople who roasted them.

To all of those lives and that labor, UCC offered its gratitude — in physical form. The result is this grave, shaped like a coffee cup.

Two: The Yakult Grave

Near UCC’s grave stands another striking one. A giant Yakult bottle.

A Yakult container, enlarged to many times its actual size, stands on the path.

The thinking is the same as UCC’s. A single bottle of Yakult contains countless living lactic-acid bacteria. Enormous quantities are consumed daily, around the world. To those countless bacterial lives, Yakult offers its thanks.

The inscription on the grave, erected by Yakult Honsha Co., Ltd. in 1964, reads in part:

“Yakult’s prosperity today has been made possible by the united efforts of our comrades, who have worked together in the hope of building a healthier society… We enshrine here the spirits of those who served in the Yakult industry, and consecrate this place as sacred ground for all who are connected with Yakult, so that it may remain a lasting memorial for those who come after us.”

And this giant Yakult-bottle grave seems to ask the viewer:

We drink Yakult every day. But have we ever, even once, offered a memorial for the souls of those bacteria?

The ordinary food and drink of daily life — each item has life, has soul. To honor that. That is the true teaching of Mount Kōya.

Three: The Rocket (ShinMaywa Industries)

Walk farther along the path, and something appears in the distance. A space rocket. To be precise, a model of Apollo 11. Two-tone white and black. The nose comes to a sharp point. Its full height makes you look up.

ShinMaywa Industries, Ltd. is a company that manufactures aircraft parts. As its corporate grave, it erected here in Okunoin the form of the Apollo 11 rocket.

There is a deep meaning in this grave.

Humanity went to the moon. It was one of the greatest scientific achievements in human history. But behind that achievement stood countless engineers, countless sacrifices, countless prayers. As a company that participated in the history of the aerospace industry, ShinMaywa honors here the souls of all who were part of it.

Space exploration and Esoteric Buddhism. The cutting edge of science and a faith eleven hundred years old. They meet on the path of Okunoin.

Four: The Termite Memorial Pagoda (Japan Termite Control Association)

The Japan Termite Control Association — the industry body for termite extermination — built a memorial pagoda at Okunoin.

For what purpose?

To honor the souls of every termite they have ever exterminated.

The pagoda is inscribed:

“Termites, rest in peace.”

The association’s own website describes it as “a symbol of compassion for the lives that, having been brought into this world, must be lost because they cannot coexist with human life, and of gratitude toward the pioneers who came before us.”

Termites are pests, from a human perspective. They eat away at houses, destroy property. They must be exterminated. But termites, too, have life. If you must kill, you must do so with gratitude — and with a proper memorial.

Each year, termite-control workers come to this pagoda in Okunoin. They press their hands together. And they bow their heads, to the termites whose lives they have taken.

Could there be a more thoroughgoing way of facing the fact of life?

There are many in this world whose work requires them to take the lives of others. Fishermen. Farmers. Slaughterhouse workers. Researchers. Medical workers. They handle life. And as long as they handle it, gratitude and a proper memorial are required.

The termite pagoda shows this principle in its most extreme form.

Five: The Fukusuke Doll (Fukusuke Tabi)

Fukusuke, a tabi-sock maker, has erected at Okunoin a statue of its corporate character — the Fukusuke doll — as its grave. The doll with the oversized head, sitting neatly. The familiar one.

It sits, beneath the cedars of Okunoin, for eternity.

It is as if the statue were saying: We honor here the souls of every tabi sock that served us, and the lives of every customer whose feet they supported.

Fukusuke, at Okunoin, bows eternally to its customers.

Six: Konosuke Matsushita (Panasonic)

This grave is said to be where the corporate-grave boom began.

Konosuke Matsushita, the founder of Panasonic, deeply revered Kūkai during his lifetime. In 1938, he erected a corporate grave at Mount Kōya for what was then Matsushita Electric Industrial. It is said to be the oldest corporate grave at Mount Kōya in the form of a registered company.

This had a profound effect on postwar Japanese executives. Konosuke Matsushita built a corporate grave at Mount Kōya. Then we must build one for our company, too. And one after another, corporate graves began to fill Okunoin.

Today, Okunoin is the largest concentration of corporate graves in Japan.

Seven: And the List Continues

Nissan Motor. Kokuyo. Kubota. Aderans. Denka. Kirin Beer. The names of countless Japanese companies are lined along the path of Okunoin.

And here is an interesting observation.

Some researchers of cemetery culture have reportedly been struck by Okunoin’s uniqueness: a coffee-cup grave, a Yakult grave, a rocket grave, a termite memorial. Few cemeteries in the world present life, industry, death, and gratitude in such inventive forms.

And few cemeteries, they say, convey such deep reverence for life and for soul.

The True Form of Okunoin

This is the essence of Okunoin.

Every one of these companies — in earnest — built its grave here, infusing it with gratitude and memorial for the products it handles, the customers it serves, the employees it relies on, and every living being connected to it.

And Kūkai accepts all of it.

“So, you have come. You too — you have come here.”

Within the mausoleum, seated, Kūkai receives each corporate grave, one by one. Warlords, imperial princes, common people, corporations, termites. Every soul gathers here, equally.

This is the true form of Okunoin.

Okunoin is not “the largest cemetery in Japan.”

It is the largest museum of life and soul in Japan.

Humans. Animals. Plants. Products. Every “existence” coexists here, eternally. And Kūkai watches over all of it.

When you walk the path, lift your gaze, just for a moment. Through the branches of the 700-year-old cedars, you may sense Kūkai watching you. Whose soul have you come here to entrust to this place? You may feel that question reaching you.

And when you reach the end of the path, you realize something. How many “lives of others” already live inside you.

The food you eat every day. The things you use every day. The people you meet every day.

All of them live, inside you.

And one day, your own life, too, will be entrusted somewhere, to someone. When that day comes, you, too, may return to Okunoin in some form.

It may be a grave. It may be a memory inside someone. It may be one of the countless souls inside Kūkai’s mausoleum.

Either way, all of us, one day, return here.

That is what Okunoin is.

Chapter 11: Where Enemies and Allies Sleep Together — Nobunaga, Shingen, Ieyasu

Walk the path of Okunoin.

You move through more than 200,000 graves and memorial pagodas. Massive cedars more than 700 years old. Moss-covered stone pagodas. Sunlight filtering down through the branches.

And at one place, your feet stop.

“Grave of Oda Nobunaga.”

No grand sign. No flashy ornament. But its presence is overwhelming.

The grave of the man who, in the Warring States period, tried to unify Japan through terror and force, is here.

And near him, another grave.

“Grave of Akechi Mitsuhide.”

The man who killed Nobunaga at Honnō-ji.

Walk a little farther, and another grave appears.

“Grave of Toyotomi Hideyoshi.”

The man who served Nobunaga as a retainer, and after Nobunaga’s death, unified the country.

Walk a little farther still, and another grave comes into view.

“Grave of Tokugawa Ieyasu.”

The man who destroyed the Toyotomi family and founded the Tokugawa shogunate, which would rule Japan for 260 years.

And here, you notice something strange.

Nobunaga, Mitsuhide, Hideyoshi, Ieyasu. While they lived, they were locked together in cycles of death. Mitsuhide brought about Nobunaga’s death. Hideyoshi defeated Mitsuhide. Ieyasu destroyed the Toyotomi line. Hatred. Betrayal. War. Slaughter. Their relationships were among the bloodiest in all of Japanese history.

And their memorials stand along the same sacred path of Okunoin.

This, even by world standards, is extraordinarily rare.

In many religious traditions, burial places preserve boundaries of faith, family, community, or lineage. The grave of an enemy lying near the grave of his killer — that, almost never happens.

But at Okunoin, it does.

Why?

Because Okunoin embodies the teaching associated with Kūkai.

Sect does not matter.
Rank does not matter.
Good or evil does not matter.
Enemy or ally does not matter.

Every soul may come here.

This is the root teaching of Esoteric Buddhism. You might call it the worldview of the mandala.

The mandala is the world of Esoteric Buddhism, depicted as an image. At the center sits Dainichi Nyorai. Around him are arranged countless buddhas, bodhisattvas, wisdom-kings, celestial beings — and human beings, animals, the natural world, every existence.

And within the mandala, every existence is equal. There is a center, but it is not a throne of exclusion. It is a center that allows every existence to find its place.

Okunoin is that mandala — built into the earth at human scale.

Kūkai sits at its center.

And arranged around him are warlords, imperial princes, common people, corporations, even termites. Every existence has its place.

Enemy or ally — it does not matter.

Every soul coexists here.

Oda Nobunaga

The grave of Oda Nobunaga.

Nobunaga was attacked in the Honnō-ji Incident, when Akechi Mitsuhide turned against him at Honnō-ji in Kyoto on June 21, 1582, and he took his own life. He was forty-nine by the traditional Japanese count. His body burned in the flames of Honnō-ji and was never found.

There is, in other words, no body.

But at Okunoin, there is a grave for him.

It is what is called a kuyō-tō, a memorial pagoda. No body lies within. But it was built to honor Nobunaga’s soul.

Here is something striking. During his lifetime, Nobunaga was at war with Mount Kōya. In 1581, he was moving to subjugate Mount Kōya. His forces attacked the mountain, and had the campaign continued, Kōyasan might have faced devastation.

And yet, Mount Kōya forgave him.

After Nobunaga died, the monks of Mount Kōya erected a memorial pagoda for him at Okunoin.

“Spirit of Lord Nobunaga — rest here, in peace.”

They took in the man whose forces had threatened their mountain.

This is the teaching of Kūkai.

Forgive your enemy. Let the past flow away like water. Treat every soul equally.

Akechi Mitsuhide

And near Nobunaga’s grave stands the grave of Akechi Mitsuhide.

After bringing about Nobunaga’s death, Mitsuhide was defeated by Hideyoshi only eleven days later. His brief rule is remembered as the so-called “three-day reign” — a rule so short, it barely lasted at all.

And the memorial pagoda for Mitsuhide, too, is at Okunoin.

The memorial pagodas of Nobunaga and Mitsuhide stand near each other.

The one who killed, and the one who was killed — sleeping near one another.

It is a sight you can see only at Okunoin.

There is, in fact, a legend about Mitsuhide’s pagoda: no matter how often it is repaired, the stone develops cracks. It is said to be the lingering resentment of Nobunaga.

Toyotomi Hideyoshi

The grave of Toyotomi Hideyoshi.

Even when Hideyoshi was still Nobunaga’s retainer, he held Okunoin in deep reverence. He built Seiganji Temple on Mount Kōya to honor his late mother; after merging with the neighboring Kōzanji Temple, it later became Kongōbu-ji.

After Hideyoshi’s death, a grave for him too was erected at Okunoin. Around it are gathered the graves of his mother Ōmandokoro, his younger brother Hidenaga, his son Hideyori, and his principal wife Kita-no-Mandokoro — the major figures of the Toyotomi family, brought together in one section.

It can be called the graveyard of the Toyotomi family.

Tokugawa Ieyasu

And right beside the Toyotomi family graves stands the grave of Tokugawa Ieyasu.

At the Battle of Sekigahara in 1600, Ieyasu defeated the retainers of the Toyotomi. And at the Summer Siege of Osaka, Hideyori was driven to take his own life, bringing the Toyotomi line to its end.

The grave of that Ieyasu stands right near the graveyard of the Toyotomi family.

This, too, is a sight you can see only at Okunoin.

The man who destroyed the Toyotomi family, and the Toyotomi family he destroyed.

Both, near one another, sleeping.

And between their graves — the graves of former enemies — modern visitors walk freely.

The hatred, the wars, the slaughter of more than four hundred years ago — they are not here.

What is here is only the quiet path of Okunoin, and the memorial pagodas lined along it.

Takeda Shingen and Uesugi Kenshin

The grave of Takeda Shingen.

And the grave of Uesugi Kenshin.

In the Warring States period, Shingen and Kenshin fought one another five times at Kawanakajima. The Battles of Kawanakajima — among the fiercest battles in all of Japanese history.

The two of them tried to kill each other. Thousands of soldiers lost their lives in their war.

And the graves of Shingen and Kenshin stand on the same path of Okunoin.

What’s more, in a striking arrangement, the memorial pagoda of Takeda Shingen and his son Katsuyori, and the richly colored mausoleum of Uesugi Kenshin — designated an Important Cultural Property — face one another across the path.

The Dragon of Echigo and the Tiger of Kai — the two great rivals of the Warring States period — face one another five hundred years later, as if back at Kawanakajima.

This too is the strange beauty of Okunoin.

And Many More

The grave of Date Masamune.

Ishida Mitsunari. Katō Kiyomasa. Yūki Hideyasu. Hori Hidemasa. Azai Nagamasa. Asakura Yoshikage. Many of the warlords who appear in Japanese history textbooks are here.

Counting them, the scale begins to overwhelm.

Okunoin can be called the final gathering place of the Warring States period.

They fought. They killed one another. And in the end, all of them came here.

And Kūkai received them.

Why They Wanted to Come Here

Why did they want to come to Okunoin?

It was believed that if you came to Okunoin, when Maitreya descended 5.67 billion years from now, you would be among those he would save.

This is the doctrine of Miroku geshō — the belief in Maitreya’s descent — in Esoteric Buddhism.

Maitreya is the buddha who will appear after Shakyamuni. When he descends, all sentient beings will be saved.

And Kūkai, at that time, will descend with him as his attendant.

If you build your grave at Okunoin, Kūkai will find you. And you will be among those saved by Maitreya.

The warlords believed this.

While they lived, they had taken countless lives. They carried the weight of guilt. They feared falling into hell after death.

But if they built their memorial pagoda at Okunoin, Kūkai would save them.

That is what they believed.

And Okunoin accepted them.

“Come. You too — come here. Your sins are forgiven. Every soul is received.”

This is the teaching of Kūkai.

The Forgotten Souls

And there is one more striking thing.

Walking the path of Okunoin, you come upon a corner called Muenzuka (無縁塚) — the mound of the unconnected.

Here are stacked countless small graves and memorial pagodas of those whose identities are unknown.

Lonely souls with no one to claim them. No family. No descendants. Remembered by no one. The unnamed, ordinary people who left no trace in history.

They, too, are at Okunoin.

Warlords and unknown commoners, lined together along the same path.

To Kūkai, they are the same.

Every soul is equal.

This is the true greatness of Okunoin.

Few places in the world feel quite like this.

Regardless of rank, regardless of sect, regardless of who was friend or enemy — every soul is received.

That teaching has been kept, unbroken, for 1,200 years.

And even now, new graves are erected at Okunoin every year.

Deeper along the path, you will find graves built in the Heisei and Reiwa eras.

Okunoin is still evolving.

So long as Kūkai is alive, Okunoin is alive.

And Kūkai is alive, eternally.

Which means — Okunoin, too, is alive eternally.

This is what it means to continue, for 5.67 billion years.

The Same Okunoin

The Okunoin the warlords saw.
The Okunoin the people of the Edo period saw.
The Okunoin the people of Meiji, Taishō, and Shōwa saw.

And the Okunoin that you are about to see.

All of them, the same Okunoin.

Kūkai does not change.

The cedars along the path do not change.

And the fact that every soul coexists here — that does not change either.

Stop Before Nobunaga

One more thing, before closing this chapter.

When you walk Okunoin, stop, for a moment, before the grave of Nobunaga.

And think about this.

This man, in his life, oversaw the deaths of tens of thousands of people. You might think he deserves to fall into hell. But he is here. He has been forgiven by Kūkai. Why?

The answer is simple.

Kūkai forgives every soul.

Because every soul comes from the universe, and every soul returns to the universe — they are all the same existence.

Nobunaga. Mitsuhide. Hideyoshi. Ieyasu. Shingen. Kenshin. While they lived, they were enemies. But after they died, all of them became the same — souls.

And every soul comes from the universe, and returns to the universe.

That returning path passes through Okunoin.

And Kūkai, on that path, sees off and welcomes every soul.

“Well done. You have made it here.”

That is what is said to every soul that arrives.

And inside that “every,” one day, you are included too.

All of us, one day, come to Okunoin.

Somewhere along the same path as the warlords.

Chapter 12: Dōgyō Ninin — The Idea That You and Kūkai Walk Together

There is, on the island of Shikoku, a path of pilgrimage.

The Shikoku Hachijūhakkasho Reijō (四国八十八ヶ所霊場) — the Eighty-Eight Sacred Sites of Shikoku — also known simply as o-henro, the Shikoku pilgrimage.

It is a pilgrimage of roughly 1,400 kilometers that circles the entire island of Shikoku. Along the way are scattered eighty-eight temples connected to Kūkai. The pilgrim visits them, one by one, in order.

On foot, the journey takes about forty-five days. By car, about ten.

Those who set out on the o-henro wear a particular set of garments.

White pilgrim robes. A white hat. In the hand, a kongō-zue — a wooden pilgrim’s staff. Carried with them, a nōkyōchō — the book in which each temple’s seal is recorded. Around the neck, a wagesa — a simplified monastic sash.

And on both the hat and the staff, the same four characters are written.

Dōgyō ninin (同行二人).

What “Two Walking Together” Means

What does dōgyō ninin mean?

Literally, it means “two companions walking the same path.”

But on the o-henro, almost everyone walks alone. They circle Shikoku by themselves. The road is long and lonely. Mountain paths. Coastal roads. Crowded towns. Rainy days. Days of storm. The feet hurt. The pack on the back is heavy.

And still, they write: Two going together.

Why?

The answer is this:

I am not walking alone. Kūkai is always beside me.

This is the true meaning of dōgyō ninin.

Beside every pilgrim walking the o-henro, Kūkai is also walking. Unseen, but undeniably there.

In the rain. In the storm. When the feet ache. When the heart is about to break.

Kūkai walks beside them.

You are not alone.

I am walking with you.

So, keep going.

That is what Kūkai conveys, without ever speaking aloud.

Those who have walked the o-henro all say the same thing.

“At first, I thought I was walking alone. But one day, suddenly, I felt as though someone was beside me. After that, my steps grew lighter.”

“The moment I realized I was not alone, the pilgrimage became something entirely different.”

This is the true form of the o-henro.

Kūkai Beside Everyone

And here, something important must be added.

The thought of dōgyō ninin is not only for the o-henro.

It is the root worldview of Esoteric Buddhism itself.

Even after entering nyūjō, Kūkai is alive. And his consciousness is not confined to the mausoleum at Okunoin.

It has diffused throughout the entire universe.

Which means — Kūkai is always, everywhere, beside everyone.

Beside the pilgrim walking the o-henro.
Beside the office worker, exhausted on the way home from work.
Beside the student struggling with exams.
Beside the patient in a hospital bed, crushed by fear.
Beside the person crying alone in the middle of the night.

Kūkai walks with all of them.

It is only that most people do not notice.

But those who have walked the o-henro notice.

“Ah — he was beside me all along.”

“I had always thought I was alone. But truly, I never was.”

This is the warmest teaching of Esoteric Buddhism.

Why Eighty-Eight Sites?

There are several theories about why the pilgrimage has eighty-eight sites. The most widely cited is that the number corresponds to bonnō — the afflictions and worldly desires that cloud the human heart.

Human beings are said to have 108 such afflictions. The 108 strikes of the temple bell on New Year’s Eve are made to extinguish them.

But the o-henro has eighty-eight sites.

Why not 108?

It is explained this way.

A journey to extinguish the eighty-eight fundamental afflictions of the human being, one by one.

By circling Shikoku, you erase those afflictions inside you, one at a time.

And when you arrive at the eighty-eighth temple, Ōkuboji —

You are released from them.

That is the ultimate goal of the o-henro.

Kechigan — The Fulfillment of the Vow at Okunoin

And after completing all eighty-eight sites, the pilgrim visits one more place.

Okunoin, at Mount Kōya.

This is called kechigan (結願) — the fulfillment of the vow.

After circling the eighty-eight sites of Shikoku, the pilgrim comes, at last, to report to Kūkai.

“O-Daishi-sama, I have completed my journey around Shikoku. You walked with me, the whole way. Thank you for walking this long road beside me. And — thank you.”

That is the prayer offered, hands pressed together before the mausoleum.

With this, the journey of the o-henro is complete.

Each year, tens of thousands of people walk the o-henro.

For their health. For spiritual practice. To honor the memory of a departed family member. To mark a turning point in life.

The reasons differ. But they all, without exception, arrive at the same place.

Before the mausoleum at Okunoin.

And there, they bow their heads to Kūkai.

O-settai — Hospitality for the Pilgrim

There is another striking tradition in the o-henro.

It is called o-settai (お接待) — a sacred form of pilgrim hospitality.

When the people of Shikoku see a pilgrim walking, they naturally call out.

“You must be tired. Please, take this.”

And they hand over tea, sweets, or a rice ball.

Sometimes they offer to take the pilgrim into their home. To let them use the bath. To drive them to the next lodging.

This is called o-settai.

It is not mere kindness toward a tourist.

The people of Shikoku see the pilgrim as Kūkai himself.

Because of dōgyō ninin — because Kūkai is walking beside the pilgrim — when you offer tea to a pilgrim, you are offering tea to Kūkai.

For the one giving o-settai, the pilgrim is an embodiment of Kūkai.

This too is a teaching of Esoteric Buddhism.

Within every person you meet, there is a buddha.

Even the stranger standing before you.

Inside that person, too, there is a buddha.

So you are kind to them.

And in doing so, you nurture your own buddha-nature.

The o-henro, and o-settai. Together, these two practices turn the whole of Shikoku into one vast field of spiritual practice.

And at its center is Kūkai, at Okunoin.

The Pilgrimage of Your Own Life

Now — let us return to our own lives.

We are not walking Shikoku. We are not wearing the white robes of the o-henro. We are not carrying a wooden staff.

But we, too, are walking the long path of a life.

The path of work.
The path of family.
The path of dreams.
The path of fighting illness.
The path of heartbreak.
The path of bereavement.

All of them are long pilgrimages.

And beside each of those paths, too, Kūkai is there.

You are not alone.

I am walking with you.

There is no voice. But there are moments when you suddenly feel it.

In the middle of the night, when you are crying in despair — it feels as though someone beside you is silently placing a tissue in your hand.

In the morning, when getting out of bed is too hard — it feels as though someone behind you is pushing you, gently, forward.

When you are cornered at work — it feels as though someone is whispering, Just a little longer. Hold on.

All of these — they are Kūkai.

Kūkai is not only inside the mausoleum at Okunoin.

His consciousness, diffused throughout the universe, is always beside us.

It is only that we do not notice.

But the moment we do notice, our lives change.

I am not alone.

With that conviction, a human being can cross any difficulty.

That is what dōgyō ninin truly means.

Turn Around at Okunoin

One more thing, before closing this chapter.

When you walk the path of Okunoin, turn around, for just a moment, and look behind you.

Someone is there.

You may not see them. But undeniably, someone is walking behind you.

It is not Kūkai.

It is everyone you have ever met in your life.

Family who have passed away.
Lovers you parted from.
Old friends.
The strangers you passed on the street.

The souls of all of them are walking with you, along the path of Okunoin.

And at the head of that long line — there is Kūkai.

You have lived your life connected to all of these people. All of them have supported you. And all of them will keep supporting you, from here on.

That is what Kūkai is telling you.

This is the true depth of dōgyō ninin.

We are not walking, two together, with only Kūkai.

We are walking with countless souls.

And Kūkai is the one who holds all of them together.

This is the greatest gift that only those who come to Okunoin can receive.

Chapter 13: Ten Places for Walking Mount Kōya Deeply

Mount Kōya is vast.

About 3.5 kilometers from east to west. A religious city of 117 temples, densely gathered. You cannot see all of it in a single day.

But if you visit the ten places introduced here, you will come to understand the true depth of Mount Kōya.

Whether it is your first visit or your tenth, walk these ten places carefully.

1. Okunoin

Okunoin is, without question, the heart of Mount Kōya.

Walk the path from Ichi-no-Hashi (the First Bridge) to the mausoleum — roughly two kilometers.

On either side of the path, cedars more than 700 years old. More than 200,000 graves and memorial pagodas. Warlords. Imperial princes. Corporate graves. All of them are here.

Cross the Gobyō Bridge, pass through the Tōrō-dō, and stand before Kūkai’s mausoleum.

This is where everything begins, and where everything ends.

The proper order for a visit is this.

Enter through Ichi-no-Hashi. Walk the path slowly. Pass Naka-no-Hashi, the Middle Bridge. Move past the Asekaki Jizō (the “Sweating Jizō”) and the Sugatami no Ido (the “Well of Reflection”). At the Gokushō, bow your head. At the Ajimi Jizō, press your hands together in prayer.

And then, cross the Gobyō Bridge.

Before you cross, always bow once toward the bridge. This is the boundary between this world and sacred ground.

After crossing, no photography. Remove your hat. Keep your voice down.

At the Tōrō-dō, press your hands together.

And behind the Tōrō-dō, before Kūkai’s mausoleum, offer the deepest prayer of all.

When you leave, return the way you came. This too is part of the proper way of visiting.

When you come to Okunoin, allow at least two hours here.

There is also a night visit. The Night Tour is guided by a monk and requires a reservation in advance. Keep it in mind if you want to see another face of Okunoin — the one we will return to in section 10 of this chapter.

2. Danjō Garan

Alongside Okunoin, one of the two great sacred sites of Mount Kōya.

The first place Kūkai laid out when he opened Mount Kōya. A vast sacred space that brings the Taizōkai mandala — the Womb-Realm Mandala of Esoteric Buddhism — into three-dimensional form on the ground.

At its center stands the Konpon Daitō, the Great Pagoda. 48.5 meters tall. A massive vermilion-lacquered tahōtō (two-storied pagoda).

Step inside, and the world changes. At the center, Dainichi Nyorai of the Taizōkai. Surrounding him, the four buddhas of the Kongōkai (the Diamond Realm). On the sixteen pillars are painted the sixteen great bodhisattvas.

This is a three-dimensional mandala.

You do not look at it as a picture. You step inside it. And you yourself become part of the mandala.

This was Kūkai’s design.

And the Sanko-no-Matsu — the pine of the three-pronged vajra, the legendary tree on which the sankosho Kūkai threw from Tang China came to rest, as written in Chapter 2 — is also here. See if you can find a pine needle that comes in a cluster of three.

3. Kongōbu-ji

The head temple of the Kōyasan Shingon sect.

Seiganji, built by Toyotomi Hideyoshi to honor the soul of his late mother, merged with another temple, Kōzanji, in the Meiji era to become the present-day Kongōbu-ji.

Step inside the main hall.

In the Ōhiroma, the Great Hall, large fusuma paintings of cranes and pines by artists of the Unkoku school open before you.

The Banryūtei, the Coiling Dragon Garden, is said to be the largest rock garden in Japan. In a sea of white sand and stone clouds, a pair of dragons appears to rise, as though guarding the inner space of Kongōbu-ji.

Press your hands together here, and simply sit.

Time stops.

That is the power of Kongōbu-ji.

4. Reihōkan

The Reihōkan, as described in detail in Chapter 8.

Twenty-one National Treasures. 148 Important Cultural Properties. Roughly 100,000 holdings. Kaikei’s Four Heavenly Kings. The works of Unkei and Kaikei. The Blood Mandala. Kūkai’s own handwritten calligraphy.

How you respond, here — that is the question.

Can you stay long, or do you want to leave quickly? That tells you something about your own spiritual sensitivity.

The admission fee is not, by any standard, cheap. But there are few places in the world where, for this price, you can see this many National Treasures.

5. Daimon

The vast vermilion-lacquered gate at the entrance to Mount Kōya.

25.1 meters tall. To its left and right stand the second-largest Niō (Kongō-rikishi) guardian statues in Japan, glaring at those who pass through.

This is no ordinary gate.

It is the starting point of the spiritual boundary that surrounds the whole of Mount Kōya.

When Kūkai cast a sacred boundary around Mount Kōya — said to extend seven ri, an old Japanese unit of distance, in each direction — this gate came to stand at the entrance to that sacred boundary.

Beyond here is sacred ground. Bring no impurity from the lower world.

That is what the Daimon says.

If you arrive at Mount Kōya by car, drive once through the Daimon before entering the town.

Even just passing through, you will feel the air change.

And the moment when the evening sun dyes the Daimon red — that is one of the most beautiful sights you can see on Mount Kōya.

6. Tokugawa-ke Reidai

The mausoleum that enshrines Tokugawa Ieyasu and the second shogun, Hidetada.

A symbol of the power of the Tokugawa family in the Edo period.

But here, what is interesting is why Ieyasu built his mausoleum at Mount Kōya.

The Tokugawa family was not originally closely tied to the Shingon school. Ieyasu himself was a follower of the Jōdo (Pure Land) school.

And still, he built his mausoleum at Mount Kōya.

Why?

Because he believed in the power of Kūkai at Okunoin.

Let my soul be watched over by Kūkai.

Even the man who took the country relied, in the end, on Kūkai.

7. Nyonin-dō

Few visitors know this place well.

Until the Meiji government abolished women’s exclusion at temples and shrines in 1872, Mount Kōya had long been known as a place of nyonin kinsei — a sacred area closed to women. Even after that decree, however, the old restrictions at Mount Kōya did not disappear overnight; they were fully abolished only in 1906.

But even during the centuries of nyonin kinsei, there were women who wished to pray to Kūkai.

For them, the Nyonin-dō — the Women’s Hall — was established.

Outside the sacred boundary of Mount Kōya, at each of the seven entrances to the mountain — known as the Kōya Nanakuchi, the Seven Gateways of Mount Kōya — a hall for women was built. One at each gateway.

Today, only one of them remains: the Fudōzaka-guchi Nyonin-dō, a small hall.

Here, unable to enter the sacred boundary itself, women pressed their hands together and offered their prayers to Kūkai.

A place where the weight of history can be felt.

8. Shukubō

Mount Kōya today has more than fifty shukubō — temple lodgings. Anyone, including travelers from outside Japan, can stay.

Stay at a shukubō, and you can eat authentic shōjin ryōri, Buddhist vegetarian cuisine. You can join the morning prayer service. You can experience sutra-copying or ajikan meditation.

This is not mere tourism. It is a direct experience of Buddhist practice.

A few recommended shukubō:

Ekōin. Well known as the base for the Okunoin Night Tour. It is also accustomed to welcoming English-speaking visitors, and is popular with travelers from abroad.

Saizen-in. Its gardens are extraordinarily beautiful. It holds the Mandala Garden designed by Mirei Shigemori.

Sekishō-in. Long in history, it holds the memorial pagoda of Takigawa Kazumasu, a retainer of Oda Nobunaga.

Ichijō-in. A shukubō connected to Akechi Mitsuhide.

Reservations can be made through the website of the Kōyasan Shukubō Association.

9. The Cable Car and the Nankai Kōya Line

This is not a place. It is the way of arriving.

But the way of arriving at Mount Kōya has itself become a kind of ritual.

From Namba in Osaka, take the Nankai Kōya Line. About two hours. Somewhere past Hashimoto Station, the landscape outside the window suddenly turns to deep mountains.

At the terminal, Gokurakubashi Station, transfer to the cable car.

The cable car climbs a remarkably steep mountain slope in about five minutes.

And then, you arrive at Kōyasan Station.

From there, a bus takes you into the town. About ten more minutes.

In total, about two and a half hours from Osaka to Mount Kōya.

You make the entire journey for this one purpose.

That, in itself, is a discipline.

If reaching Mount Kōya were too easy, the sense of gratitude would be lost.

That is what believers say.

Perhaps only when the journey takes effort does the meeting with Kūkai feel complete.

That is the rule of Mount Kōya.

10. Mount Kōya at Night

This is not so much a place as a time.

During the day, Mount Kōya is full of visitors. But after 5 p.m., most day visitors leave.

And the Mount Kōya of night begins.

Without an overnight stay, you cannot truly see Mount Kōya at night.

At night, look out the window of your shukubō. The town is silent.

The dim street lights are few. Beyond them, the cedars more than 700 years old stand illuminated by the moon.

Only the sound of the wind.

This is the true Mount Kōya.

The path of Okunoin, crowded with visitors during the day, transforms into another world at night.

If you join the Night Tour, a monk will guide you along the nighttime path. You walk by the light of paper lanterns alone.

You cross the Gobyō Bridge in the dark.

And the countless flames of the Tōrō-dō shine in the darkness like a galaxy.

When you see that, you understand.

This place is connected to the universe.

The Mount Kōya of night shows you the true world of Kūkai.

How to Walk These Ten

These are the ten places.

To see all of them, you need at least one overnight stay. Two nights, if possible.

A day trip is enough, isn’t it? — some may wonder.

But on a day trip, you cannot see Mount Kōya at night. You cannot taste the shōjin ryōri of a shukubō. You cannot join the morning prayer service.

And without those, the true form of Mount Kōya stays hidden.

Please, stay one night at a shukubō.

At night, open the window of your room, and breathe deeply.

In that moment, you will understand, for the first time:

Ah — I am breathing the same air as Kūkai.

From that moment on, Mount Kōya is no longer just a tourist site.

It becomes a part of your own life.

Epilogue: The Meaning of Being Called

Thank you for reading this far.

This is what has been written here about Mount Kōya.

Kūkai’s almost superhuman life. The three-pronged vajra that flew from Tang China. The unexpected thread connecting Esoteric ritual implements and Nazi Germany. Nyūjō — the choice of eternal meditation. The meal that has been carried, twice a day, for 1,200 years. The vision Kangen saw when he opened the mausoleum. The shared Sanskrit root between the Akashic Records and Kokūzō. Those who cannot stay long inside the Reihōkan. The unbelievable accounts gathered at Okunoin. The corporate graves shaped like coffee cups and rockets. Enemies and allies sleeping along the same path of Okunoin. The warm thought of dōgyō ninin. And the ten places for walking Mount Kōya deeply.

If you have read this far, you already understand.

Mount Kōya is not merely a tourist site.

It is the one place where the universe and humanity remain connected.

And at its center is Kūkai. Twelve hundred years ago, he entered eternal meditation, and even now, he sits inside the mausoleum at Okunoin.

And Kūkai, with the door of the cosmic library held open, waits for humanity to arrive.

Why You Are Called

Now, return to the first question.

In the prologue, this was written:

There is a mountain you cannot reach unless it calls you.

Why does a person come to be called to Mount Kōya?

Here, at the end, is the answer.

In a life, there are turning points.

When work is not going well.
When relationships within the family have grown strained.
When you have lost someone precious.
When you no longer know what you are living for.
When illness comes.
When, suddenly, you want to stand still.

In times like these, a person reaches for something.

They reach for an answer.

But modern society offers no answer. Open your smartphone, and social media simply scrolls by. The news is mostly noise. Advice contradicts itself.

And then, in a moment like that, a single word drops into your mind.

Kōyasan.

At first, you ignore it. You have no idea why, suddenly, Mount Kōya.

But from that day on, strange things begin to happen.

A television program is featuring Mount Kōya. At the entrance of a bookstore, books on Mount Kōya are stacked high. Someone nearby is speaking about Mount Kōya.

This is no coincidence.

The moment you realize that — you are being called.

And so, you take some time off. You take the train, the cable car, and the bus. After about two and a half hours, you climb Mount Kōya.

You walk the path of Okunoin.

The 700-year-old cedars.

The 200,000 graves and memorial pagodas.

And you cross the Gobyō Bridge.

In that moment, something happens.

The tears may not stop.

Your mind may go suddenly, deeply quiet.

You may hear the voice of someone in your family who has passed.

You may understand your mission in life.

Or — nothing visible may happen at all.

But looking back later, your life will have changed from that day forward.

That is the power of Mount Kōya.

Being Called Is Not Being Chosen

And there is one more thing that must be written.

Being called does not mean being chosen.

It is not that only special people are called.

Every person, one day, will be called — without exception.

It is only that the timing differs from person to person.

Some are called at twenty.
Some are called at fifty.
Some are called just before they die.
Some are called only in another life.

But every soul, in time, arrives at Okunoin.

And Kūkai knows this.

“Come whenever you wish. I am here, waiting.”

That is what Kūkai is saying, smiling.

Go, Without Hesitation

In closing — if, having read this, you feel “I want to go to Mount Kōya”:

Go, without hesitation.

It is not coincidence.

You are being called, now.

And at Okunoin, Kūkai is waiting for you.

“So, you’ve come.”

Go to hear that one phrase.

And inside the Tōrō-dō, in its galaxy-like light, take a moment to look around you.

Countless lights, gently swaying.

They are O-teru’s single lamp, and the lamp of the retired Emperor Shirakawa, and each of the prayers offered by all the countless people who have come to Okunoin before you.

And one day, when you come to Okunoin again, your own prayer will be among that light as well.

This is what Okunoin is.

A place where time stops, where space connects to the universe, and where every soul coexists.

A place that only those who are called can reach.

And a place that changes, forever, those who reach it.

That is Okunoin, on Mount Kōya, in Wakayama Prefecture.
