A disgraced god arrives in a province he has never seen, with nothing, and the first thing he notices is a chopstick going past in the river. Someone upstream is eating. It is a small, sharp piece of observation, and it is the reason the Kojiki's most satisfying story feels less like a monster legend than like a detective arriving in a town.
Downstream of a problem
Susanoo had been fined, shaved, stripped of his nails and thrown out of heaven for what he did to his sister's fields and weaving hall. He came down at Torikami, at the headwaters of the Hi river in the land of Izumo, and followed the chopstick up.
He found an old man and an old woman sitting with a girl between them, and all three of them crying. The old couple were Ashinazuchi and Tenazuchi — the foot-stroking elder and the hand-stroking elder, names that sound like the gestures parents make over children — and they were the children of the mountain deity Ōyamatsumi. They had had eight daughters. Something came every year and took one, and it had taken seven, and it was due again, and the girl between them was called Kushinada-hime and was the last.
Susanoo asked what the thing was, and their description is the best set of specifications in Japanese myth. One body, eight heads and eight tails. Eyes the red of winter-cherry fruit. Moss growing along its back, with cedar and cypress standing up out of it like a wooded ridge. A length that covered eight valleys and eight hills. And, underneath, a belly that was permanently raw and oozing blood.
Eight gates, eight vats
He asked for the girl. When they hesitated, he told them who he was — the sun goddess's brother, freshly down from heaven, a fact he offered without any of the accompanying context — and they gave her to him at once.
Then he took her and turned her into a many-toothed comb, and pushed the comb into the bunch of his hair. The story does not explain this and never returns to it, and it is one of the eeriest things in the text: the woman he has just married spends the entire fight as an object in his hairstyle.
His instructions to the parents were practical. Brew sake and refine it eight times over, until it is far stronger than anything ordinarily drunk. Build a fence, and set eight gates in it. At each gate build a platform, and on each platform put a vat, and fill each vat with the sake. Then wait.
The serpent came as it always came, put one head into each of the eight vats, drank all of it, and went to sleep.
Susanoo drew the ten-span sword he wore and went through it. He cut the heads and he cut the body, and the Hi river ran red, which is a detail the story states plainly and which people have been arguing about ever since. When he came to the middle of the eight tails the edge of his blade turned, and he stopped and cut the tail open lengthwise, and inside it was a sword — a great, sharp blade that had no business being in an animal.
He recognised that this was not his to keep. He sent it up to heaven with an account of how he had come by it, and made a present of it to the sister he had so recently ruined, which is the closest thing to an apology he ever offers. Its name at that point was the sword of the gathering clouds of heaven; it acquired the name Kusanagi much later and for an entirely different reason, in the hands of a hero who used it to cut himself out of a grass fire.
The house at Suga, and the first poem
Susanoo then went looking for a place in Izumo to build a house with his wife, restored from comb to woman. He came to a district that made him feel, he said, refreshed and clean — and that word is why the place is called Suga. As he began building, clouds rose thickly around the site, and he made a short song about them: the many clouds standing up, the many-layered fence of Izumo, a many-layered fence to keep his wife inside, and the fence again at the end.
Japanese tradition treats this as the first waka ever composed, the origin point of the whole classical poetic tradition, and it is worth noticing what kind of poem it is. It has no metaphor and almost no vocabulary. It says "fence" three times. Its entire effect comes from repetition and from the pun between rising cloud and rising palisade, and a violent, exiled god has just spoken the founding text of the most refined art in Japanese culture. He then appointed his father-in-law as steward of the palace, and the line of his descendants runs down to Ōkuninushi, who inherits Izumo and eventually has to hand it over.
The sources, including the one that leaves it out
The Kojiki (712) and the Nihon Shoki (720) both carry the story, and the Shoki — as usual — gives alternative accounts alongside its main version, several of which change things that matter:
- In one variant, Susanoo does not come straight down to Izumo at all. He descends first to Soshimori in Silla, on the Korean peninsula, decides he does not want to be there, and crosses to Izumo in a boat made of clay. This is the chronicle openly locating a major deity's origin off the archipelago, and it has been read — cautiously — as a trace of the very real Korean-peninsular connections of the Izumo and northern Kyushu regions.
- In another, the sword found in the tail carries a different name.
- In another, Susanoo plucks out his facial and body hair and scatters it, and each kind becomes a different useful tree — cryptomeria, cypress, camphor, black pine — and he assigns each its purpose: this one for boats, this one for houses, this one for coffins. Then he sends his children to plant the seeds across the country. A rampaging storm god turns out, in one telling, to be the founder of Japanese forestry.
And then there is the awkward one. The Izumo Fudoki, compiled in 733 as an official regional gazetteer of the very province where all of this is set, gives Susanoo only brief, mostly place-name notices — and does not tell the serpent story at all. The local record of Izumo, written within a generation of the chronicles, does not contain Izumo's most famous legend. What that means is genuinely unresolved: it may show the tale was a court composition attached to Izumo rather than a local one, or simply that a gazetteer had a different job to do. Either way, anyone who describes the Orochi story as "the ancient legend of Izumo" is stating more than the sources support.
The readings — offered as readings
The image of a river with eight branching heads and a bloody underside, in a district whose river ran red, has attracted explanations for a very long time. Three are worth setting out, on the explicit understanding that none of them is what the text says.
The flood reading. The Hi is a braided river prone to violent seasonal flooding; the serpent's eight tails are its distributaries, its annual arrival is the flood season, and the girls it consumes are the fields and the people the flood takes. Killing it is river control, and marrying the last daughter — whose name contains the word for rice paddy — is the resulting agricultural security.
The iron reading. Okuizumo is one of the historic centres of tatara iron production, smelting from iron sand washed out of the hills. The process discolours watercourses with iron oxide, which fits a red river and an inflamed belly; and a sword found inside the creature's body is a fairly direct image of steel coming out of a mountain valley. This is elegant, widely repeated, and unproven.
The sacrifice reading. A yearly demand for a young woman, met until someone refuses to meet it, is a story pattern found from Greece to South Asia to the Rhine, and it is often taken as a memory of propitiatory sacrifice. There is no archaeological evidence for annual human sacrifice in Izumo, and the pattern's very wide distribution is at least as easily explained by its usefulness as a plot.
The comparison most readers reach for is Perseus and Andromeda, and the structural match — annual victim, hero, monster, marriage — is real. Whether that indicates any historical relationship between the traditions is not something the evidence can currently settle, and the differences are as interesting as the similarities: the Japanese hero disguises his bride rather than displaying her, wins by preparation rather than by weapon, and takes nothing away from the fight except a sword he immediately gives to someone else.
Questions that follow the story
What happened to the sword afterwards?
It went from heaven back down to earth, was kept at Ise, and was given to the hero Yamato Takeru by his aunt when he went east; in the Kojiki he uses it to cut back burning grass in an ambush, and it takes the name of the grass-cutter from that. He leaves it with his wife Miyazu-hime, and it stays at Atsuta Shrine in Nagoya, where it is claimed to be still. It is also claimed to have gone into the sea at Dan-no-ura in 1185 with the child emperor Antoku, and Atsuta's answer — that the blade lost at sea was a replica — is exactly what a shrine holding a national treasure would say, whether or not it is true. The name's meaning is disputed too: a minority proposal connects the first element to an old word for snake rather than grass, which would make it the serpent-sword and the grass-cutting an after-the-fact explanation.
Is Yamata-no-Orochi a dragon?
Not in the way East Asian dragons are usually meant. Continental dragons in Chinese and Japanese tradition are typically benign, associated with water and rain and imperial authority. This creature has no wings, no claws worth mentioning and no dignity; it is a serpent grown to landscape size, and the vocabulary the text uses is the vocabulary of snakes. Its shrine-adjacent afterlife in Japan keeps it distinct from the ryū of Buddhist and Chinese-derived material.
Where can you see it performed?
In Shimane, constantly. Iwami kagura, the vigorous folk-shrine dance tradition of the western part of the prefecture, has an Orochi piece in which multiple performers work full-length serpent costumes of coiled bamboo and paper simultaneously — often four, six or eight of them, filling a stage with writhing bodies and smoke — while Susanoo works through them one at a time. It is the most exciting piece of live traditional performance in Japan, it is done at village festivals rather than in theatres, and it is the reason the story stays alive locally in a way the written sources alone would never have managed.
Why is Kushinada-hime turned into a comb?
No one knows, and the text offers nothing. The most common suggestion is that it is a pun-driven detail — her name contains an element that can be heard as "comb", so the comb both hides her and explains her name — and that the Kojiki is fond of exactly this kind of wordplay. Ritual readings, in which the comb is a receptacle for a spirit and the episode encodes a possession rite, exist and are speculative. What is clear is that she does not stay an object: she comes out of his hair, becomes his wife, and stands at the head of the Izumo line.
