The Tale of the Eight-Forked Serpent
At a Glance
- Central figures: Susa-no-o, the God of Storms, banished from the heavens; Kushinada-hime, the last surviving daughter of the elderly couple Ashinazuchi and Tenazuchi; and Yamata-no-Orochi, the eight-headed, eight-tailed serpent.
- Setting: Izumo Province - the banks of the Hi River and the surrounding land - following Susa-no-o’s expulsion from Takamagahara, the heavenly realm.
- The turn: Susa-no-o encounters the weeping family of Kushinada-hime and devises a plan to destroy Yamata-no-Orochi using eight vats of sake before the serpent can claim her.
- The outcome: Susa-no-o slays the serpent, discovers the sword Kusanagi-no-Tsurugi hidden inside its fourth tail, presents it to Amaterasu, and settles in Izumo with Kushinada-hime.
- The legacy: The Kusanagi-no-Tsurugi became one of the Three Sacred Treasures of Japan, alongside the Yata no Kagami and the Yasakani no Magatama, held as symbols of the imperial lineage; Susa-no-o and Kushinada-hime established Izumo Taisha, one of Japan’s oldest Shinto shrines.
The old couple knelt at the edge of the Hi River and wept. Beside them stood their daughter, Kushinada-hime, silent in the way that people are silent when grief has gone beyond words. Susa-no-o had only just arrived in Izumo, stripped of heaven and still carrying the heat of his sister’s anger, and he almost walked past them. He did not.
What he learned, standing there on the riverbank: Ashinazuchi and Tenazuchi had once had eight daughters. Yamata-no-Orochi - eight heads, eight tails, a body so vast it crushed whole hills as it moved - came to them every year. Every year it took one daughter. Now only Kushinada-hime remained, and the season was turning.
The Banishment
Susa-no-o had not left Takamagahara quietly. His expulsion came at the end of a long season of ruin - rice paddies broken open, a sacred horse flayed and thrown through the roof of Amaterasu’s weaving hall, a maiden dead at her shuttle in the panic that followed. Amaterasu had shut herself into a cave. The heavens went dark. What came after is another story, but when the light returned, Susa-no-o was cast out.
He fell to Izumo. The province received him without ceremony - just wind off the sea, the sound of the Hi River, the smell of cedar. He was a storm god without a storm to govern. He roamed.
The Eight Vats of Sake
He made Kushinada-hime a comb and set her in his hair, close and safe, before he began. Then he gave his instructions to Ashinazuchi and Tenazuchi: build a fenced enclosure with eight platforms, set a great vat of strong sake on each one, and wait.
When Yamata-no-Orochi arrived, all eight heads caught the scent at once. Each head found its own vat and plunged in. The serpent drank. The sake was strong - brewed for exactly this - and one by one, the great heads grew heavy, drooped, and lay still. Eight heads on the ground, eyes shut, the body heaving in slow, sodden breath.
Susa-no-o drew his sword. He worked methodically, head to head, tail to tail. The serpent did not wake. By the time he finished, the river ran the color of rust.
The Sword Inside the Tail
When he cut through the fourth tail, his blade stopped. Something inside resisted - not bone, not gristle, but a hard and deliberate obstruction. He cut carefully around it.
Inside the tail lay a sword. It was unlike anything he carried. He stood with it a moment in the bloody grass, turning it. The blade held a stillness that his own weapons never had.
He called it Kusanagi-no-Tsurugi - the Grass-Cutting Sword - though that name would come into its full meaning later, in other hands, in other fields. For now, he recognized that it did not belong to him. He wrapped it and set it aside for Amaterasu. It was the most honest gesture he could make: a thing of clear power, offered without condition, across the distance his own recklessness had opened between them.
Kushinada-hime and Izumo
He took Kushinada-hime from his hair and returned her to herself. They were married in Izumo, with her parents as witnesses. He composed a poem for her - the first waka in the Japanese tradition, it is sometimes said - describing the cloud-banks rising over Izumo and the many-layered room he would build for her. Whether or not that is literally true, the poem was remembered when many other things were not.
He settled there. He built. The violence that had made him unwelcome in heaven found different expression in the work of clearing land, governing the province, raising what would become Izumo Taisha - a shrine that still stands, one of the oldest in Japan, its great thatched roof visible from the road.
What Remained in Izumo
Kusanagi-no-Tsurugi passed to Amaterasu, and from her eventually into the possession of the imperial family, where it joined the sacred mirror and the sacred jewel to form the three imperial treasures. The sword is kept at Atsuta Shrine in Nagoya. It is not displayed. Most people alive today have never seen it and never will - but its existence is not in doubt, and the story of where it came from is told in the same form it has always been told.
Susa-no-o spent the rest of his time in Izumo. The chaos that had defined him in the chronicles of heaven does not appear again in the same way. He governed. He built. The Hi River moved past Izumo the way rivers move - indifferent to what happened on their banks, carrying the season forward into the next one.
