Folklore, retold
The story as it is told
A retelling, not a citation. What follows is the story as the most widely circulated popular accounts tell it — folklore encyclopedias, translations, and the versions that have travelled furthest. It is synthesized rather than keyed line by line to the dated primary texts, and popular versions drift from what those texts actually say. The cited, source-by-source record begins further down this page, and where the two disagree, the record wins.
Three severed heads, fighting each other in the sea off Manazuru, forever.
How they got there
The Kamakura period. Three warriors — Kozata, Matashige, and Akugorō — fall into a quarrel at a local festival.
Swords come out.
Akugorō, the strongest of them, beheads Kozata. Then he chases Matashige up into the hills — and the two of them lose their footing and go over, into the sea.
And then the marvel.
Their severed heads went on fighting in the water.
Kozata's head biting Akugorō's. All three locked together under the waves, still at it, not stopping.
You can see them
The heads show as fire on the water at night.
And by day, as a distinctive spiral pattern in the waves — a whirlpool, named locally the Tomoe Whirlpool.
That name is doing real work. The tomoe is the three-comma whirl you see everywhere in Japan: on taiko drums, on shrine roof-tiles, on family crests — three curved shapes chasing each other around a centre, endlessly, none of them catching the one in front.
Which turns out to be a diagram of the thing itself. Three angers going round a circle with no exit, drawn as a design that Japan puts on everything and never thinks about.
It's a closed circuit
Here's what makes the maikubi different from every other grudge in this collection.
Every other vengeful spirit needs a living target.
The poisoned wife comes back for the husband who killed her. The vengeful courtier's spirit strikes the capital that exiled him. The Kasane cycle possesses wife after wife of the man who murdered her. The wrath is always aimed at somebody who is still alive, and it usually ends when the account is settled or a priest intervenes.
The maikubi need only each other.
There's no victim. Nobody living is haunted. No priest can exorcise it, because there is nobody to exorcise it for — the only parties involved are the three heads, and all of them are perpetrators.
The quarrel outlived the men, and then it outlived the era, and it is still going in the water off a real town in Kanagawa.
That makes it the tradition's purest statement of something it otherwise only implies: rage is self-sustaining once it's fed. It doesn't need an object. It doesn't need justice. Three people who wronged each other equally will keep it running by themselves, indefinitely, with no one else required.
The other version
There's a variant preserved alongside the artwork, and it's grubbier and possibly better.
They weren't warriors. They were gamblers — executed, and thrown into the sea.
And their heads stayed magically joined, and arguing.
Not fighting a duel. Arguing. Three dead cardsharps, tied together at the bottom of the bay, still disputing whatever it was.
Manazuru is still there, incidentally. So is the whirlpool.

Overview
Three severed heads fighting each other in the sea off Manazuru (Kanagawa), forever — Ehon Hyaku Monogatari (1841) [ehon-1841]. The tale is set mid-Kamakura: three warriors — Kozata, Matashige, and Akugorō — quarreled at a Manazuru festival; swords out; the powerful Akugorō beheaded Kozata, chased Matashige into the mountains, and the two "lost their footing and tumbled into the sea." Then the marvel: "their severed heads continued fighting in the water" — Kozata's head biting Akugorō's — three heads locked in eternal combat beneath the waves, showing as fire on the water at night and a distinctive spiral wave-pattern by day, named the Tomoe Whirlpool [ja-maikubi].
A variant preserved with the artwork: the three were gamblers, executed and thrown into the sea, their heads staying "magically joined and arguing" [ja-maikubi].
The reading
The wrath-system's closed circuit. Every other grudge in the tradition needs a living target — Oiwa needs Iemon, the goryō need the state. The maikubi need only each other: perfect mutual grievance, no victim, no exorcism possible because no one is haunted but the haunters. The tomoe — the three-comma whirl on every taiko drum and shrine roof — becomes the diagram of the thing: three angers chasing each other's tails in a circle with no exit. The quarrel outlived the men, the war, the era; the site can run it as the tradition's purest statement that rage is self-sustaining once fed.
Geographic note for the places page: Manazuru still exists; a named local whirlpool-legend with a picture-book pedigree is exactly the site's pin-on-the-map material.
