Ōmononushi

Ōmiwa Shrine, at the foot of Mount Miwa, is one of the oldest shrines in Japan.

And it has no main hall.

There's no building housing the god. There's no inner sanctum with a mirror or a sword in it. You walk up to the worship hall, and beyond it there is the mountain, and that's the god.

Not a mountain where a god lives. The mountain is the body.

This is the oldest surviving form of Japanese religion still in operation, and everything else in this collection presupposes it — every mountain-spirit, every tree that shouldn't be cut, every rock with a rope around it. Here it is unmediated, at a major shrine, today.

The god is Ōmononushi. And he is a snake.

The comb box

His wife was Yamato-totohi-momoso-hime.

He only came at night. That's the arrangement — he arrives after dark, he leaves before light, and she never sees him.

She asks to see him. Just once. In the morning.

And he agrees — with a condition. I will be in your comb box. Do not be startled.

She opens the box in the morning.

Inside is a small black snake.

And she screams.

He leaves — humiliated, having kept his word and been recoiled from anyway. And in her distress she falls, and is fatally injured by a chopstick.

Her tomb is the Hashihaka — "chopstick grave" — a genuine keyhole-shaped burial mound at Sakurai, one of the great early kofun. It is still there. You can stand at the edge of the moat.

Which makes it the don't-look rule with an address

This tradition returns obsessively to one clause: a supernatural spouse asks you not to look, and you look, and the marriage ends.

The sea-princess giving birth in the birthing hut. The crane wife at her loom. Izanagi with his comb-tooth torch in the underworld.

It's the most-repeated rule in Japanese myth.

And the Miwa version is the one with an archaeological site attached. A monument, in earth, at a known location, to a broken marriage taboo.

The thread through the keyhole

There's a second wife, and a second tale, and it's the better piece of detective work.

Ikutamayori-hime becomes pregnant, and her parents want to know by whom — because the visitor comes only at night and is gone by dawn.

So they tell her to sew a hemp thread into the hem of his robe.

In the morning they follow it.

It runs out of the room through the keyhole — through a gap no man could pass — across the country, and up to Mount Miwa.

And left behind on the spool: three loops.

Mi-wa. Three rings.

The mountain's name is the story's receipt.

The plague

Under Emperor Sujin, a pestilence was killing a great part of the population.

And the god appeared in dreams with a demand — not sacrifices, not a temple, not gold.

He wanted a specific man to conduct his rites: Ōtataneko, who was his own descendant.

They found him. He performed the rites.

And the pestilence ended.

That is the wrath-settlement pattern — the same one that later gets applied to the ghost of an exiled scholar and the head of a beheaded rebel — running here, in the earliest chronicles, centuries before anyone had a word for it.

And note the shape of the demand. The god isn't angry about the offerings. He's angry about the personnel. The rites were being performed by the wrong people. Get the right man in the post and the plague stops.

The oldest supernatural crisis in the Japanese record was resolved by a staffing correction.

And you can see it from the street

Walk past any sake brewery in Japan and look above the door.

There will be a sugidama — a large ball of cedar sprigs, bound tight, hung out when the new brew is started. Fresh green when it goes up; brown by the time the sake is ready.

That's Miwa's cedar.

Ōmononushi is the patron of brewing, and every brewery in the country hangs a miniature of his mountain's tree over its entrance to say we are under this god's protection and the new sake is coming.

The snake-mountain, reduced to a sphere the size of a beach ball, over a shop door, in every sake town in Japan.

Why this entry matters more than it looks

If you want a single case proving that Japan's monsters are continuous with the oldest stratum of its religion, it's this one.

The animal-spouse contract. The don't-look catastrophe, with a burial mound as evidence. The traced thread, a device a dozen later tales reuse. The plague settled by appeasement. And the mountain as a body.

Every piece of machinery that runs a thousand later stories is already turning at Miwa, in the third-century chronicles, at a shrine that never got around to building a hall for its god because it already had one.
