Yamata no Orochi

Quick facts

What the source says

After his expulsion from heaven, Susanoo descends to Tori-kami. Floating chopsticks lead him upstream to a weeping couple and their daughter. The father, an earthly deity, explains that he originally had eight daughters: the serpent has come each year and devoured one, and its next arrival is due. He describes the body and its enormous extent before the serpent appears.^{[1: XVIII, opening dialogue]}

Susanoo asks for the remaining daughter. After he identifies himself, her parents agree. He transforms her into a comb and places it in his hair. He then orders liquor prepared, with a fence, eight gates, platforms and vats. The serpent arrives, dips its heads into the vats, drinks, becomes intoxicated and sleeps. The comb transformation is Susanoo’s action, not the serpent’s ability.^{[1: XVIII; notes 9, 16–17]}

Susanoo cuts the sleeping serpent into pieces with his ten-grasp sabre, and its blood changes the River Hi into a river of blood. When he cuts the middle tail, his blade’s edge breaks. Opening the flesh, he finds a great sword within and informs Amaterasu, the Heaven-Shining-Great-August-Deity. The narrator identifies the discovered weapon as the Herb-Quelling Great Sword, Kusanagi.^{[1: XVIII, conclusion; notes 19–20]}

Description and limits

The father describes one body with eight heads and eight tails, extending across eight valleys and eight hills. Moss, chamaecyparis and cryptomerias grow on it. Its belly is continually bloody and inflamed; its eyes are compared to akakagachi, glossed in the text as hohodzuki and in Chamberlain’s note as winter-cherry. This comparison does not give the whole body a colour.^{[1: XVIII; notes 11–13]}

The landscape-scale description supplies no modern measurement. Section XVIII does not describe wings, count legs, give the serpent speech, or attribute fire-breathing, venom, regeneration or weather control to it. The sword lies within its flesh; the episode does not say it deliberately guards a treasure hoard.^{[1: XVIII]}

Source realm: Izumo in the Kojiki

This record uses mythic cosmos for a divine narrative set at the headwaters of the River Hi, also Hii in Chamberlain’s note, in the land he spells Idzumo. Izumo is the modern spelling used here. Koshi is the serpent’s stated provenance, not the location of this encounter. Chamberlain’s note describes a broad historical designation; it does not justify a precise modern range for the serpent.^{[1: XVIII; notes 1–2, 10]}

Translation and version boundaries

Liquor and platforms. Chamberlain renders the preparation as distillation, but note 16 discusses brewing and identifies the drink as sake. This record therefore says that liquor is prepared, without treating the wording as a technical recipe. His literal platform instructions imply eight at each gate; note 17 argues that eight in total were intended. No exact construction plan is reconstructed here.^{[1: XVIII, notes 16–17]}

Reporting or sending the sword. The translated main text says Susanoo informs Amaterasu. Note 19 records an alternative reading in which he sends the sword with a message, influenced by the parallel Chronicles of Japan account. This profile preserves Chamberlain’s chosen reading rather than silently merging them. His references to the Chronicles are comparative notes, not a second primary reading basis for this record.^{[1: XVIII, note 19]}

Threat, strategy and discovery

The narrative moves from a family’s repeated losses to a deliberately prepared trap, then to the unexpected discovery of a sword. Strategy makes the overwhelming body vulnerable. This is an editorial reading of the episode’s sequence; the passage does not explicitly identify the serpent as a symbol of floods, evil or any universal natural force.^{[1: XVIII]}
