Susanoo Slays the Yamata no Orochi

At a Glance

• Central figures: Susanoo, the storm god exiled from the heavens; the Yamata no Orochi, an eight-headed serpent; Kushinada-hime, the last surviving daughter of the elderly couple Ashinazuchi and Tenazuchi.
• Setting: The land of Izumo, in the age of the gods; a riverbank where an old couple mourns their daughters, one by one taken by the serpent.
• The turn: Susanoo devises a plan to intoxicate the Orochi with eight vats of sake and cuts it apart while it sleeps, finding a sword hidden inside one of its tails.
• The outcome: The Orochi is destroyed, Kushinada-hime is saved, and Susanoo presents the recovered sword to his sister Amaterasu as a gesture of reconciliation.
• The legacy: The sword found inside the Orochi’s tail became Kusanagi-no-Tsurugi, one of Japan’s three imperial treasures, a symbol of divine authority that persists to the present day.

Susanoo had already done considerable damage before the exile. He wept for his dead mother until the mountains shook. He broke his sister’s rice paddies, filled in the irrigation ditches, fouled the sacred weaving hall. When Amaterasu shut herself inside her cave and the world went dark, it was Susanoo who had driven her there. The other gods stripped him of his powers and cast him out of the heavens. He fell to earth in Izumo, alone, with nothing particularly to recommend him.

It was beside a river that he heard the weeping.

The Old Couple by the River

An old man and an old woman sat together on the bank. Between them, a young woman - their daughter, Kushinada-hime. Susanoo asked what had happened to them. Ashinazuchi, the old man, told him: they had once had eight daughters. Each year the Yamata no Orochi came, and each year it took one. Seven daughters were gone. Now only Kushinada-hime remained, and the time was coming again.

Susanoo looked at the girl. He told Ashinazuchi he would kill the serpent. He asked for Kushinada-hime’s hand in return.

The old man agreed without hesitation.

The Yamata no Orochi

The Orochi was not a snake in any ordinary sense. Eight heads. Eight tails. Its body lay across eight valleys and covered eight hills, and pine trees and moss grew along its back the way they grow on old stone. Its eyes burned the color of ripe cherries. When it moved, the ground remembered it.

Every family in the land knew what it was to wait for the year to turn and wonder which daughter would not be there come spring. The Orochi had no purpose in the stories except hunger. It did not speak. It did not bargain. It simply came.

Susanoo knew a direct fight would likely go badly. He made a different plan.

Eight Vats of Sake

He instructed Ashinazuchi and Tenazuchi to build a fence with eight gates. Behind each gate, a platform. On each platform, a vat of sake - brewed strong, eight times refined. Then they waited.

The Orochi came. Each of its eight heads found a gate, pushed through, lowered itself to the vat beneath, and drank. The sake was stronger than anything the serpent had tasted. One head at a time, the Orochi sank into a heavy, stuporous sleep, each neck curling down against the platform until all eight heads lay still and the vast body settled across the hillside like a fallen wall.

Susanoo stepped forward and drew his sword. He cut through the first neck, then the second. He moved along the length of the body, methodical, working through all eight heads and then back along the tails. When his blade reached the fourth tail, it struck something and stopped. Not bone. He cut more carefully and pulled the obstruction free.

A sword. Longer and finer than anything he had seen. It gleamed in a way that had nothing to do with reflected light.

Kusanagi-no-Tsurugi

Susanoo recognized that a sword found inside the body of such a creature was not his to keep. He named it Kusanagi-no-Tsurugi - the Grass-Cutting Sword - and sent it to Amaterasu. It was the only apology he had that carried any weight. She accepted it. The sword passed into the keeping of the heavens and eventually into the keeping of the imperial line, where it remains among the three sacred treasures of Japan alongside the mirror and the jewel.

Susanoo married Kushinada-hime. He composed a poem on their wedding night - the first waka poem, it is said, thirty-one syllables describing the clouds building over Izumo, a many-layered fence of clouds, a fence to enclose his new wife within. He had spent his entire mythic life tearing things down. The poem was the first thing he built.

What Remained in Izumo

The bodies of the Orochi’s eight heads and eight tails lay across the hills. The sake vats stood empty. The old couple, Ashinazuchi and Tenazuchi, went home with their daughter still living.

The sword moved upward, out of the story and into the history of a dynasty. Kusanagi-no-Tsurugi would travel through centuries, passing from one pair of hands to another, and one day a general would use it to cut back burning grass on a field where an enemy had set fire to trap him. The name would make sense then. But that night in Izumo it was simply a sword, cleaned of serpent blood, wrapped carefully, and sent to a sister who had reason enough not to forgive her brother and apparently chose to anyway.
