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.
At night, hanging from a tree branch — or protruding from the wooden slats of a fence — is a horse's leg.
And the record's one behavioural note:
"Those who approach carelessly will be kicked."
That is the entire creature. A leg, waiting, with follow-through.
Where it's told
Fukuoka, at Kurazuka: a tanuki conjured "an approximately ten-foot horse's leg to trick travellers at midnight."
Which is the trickster attribution doing what it always does on Kyushu's margins — if something inexplicable happens, a shapeshifting animal arranged it.
Yamaguchi, in the Iwamura Kaidanroku — a proper Edo horror collection — has the leg suddenly protruding from a fence on rainy nights.
And the naturalist floor is right there
The record itself supplies it: branches protruding from fences and hedges in the dark.
Which is exactly right, and it's the shape a wet bough makes when a lantern swings past it — a thick angled limb, catching light on one side, at roughly knee height, appearing out of a hedge you have walked past a thousand times.
The kernel is real. The species is supplied by the mind's inventory.
Same mechanism as the crabs whose shell-markings look like samurai faces: the input is genuine and ambiguous, and the brain resolves it into whatever is already on the shelf.
And what's on the shelf, in western Japan, is a horse
Because here is the strange thing about this entry, and it only becomes visible when you put three creatures side by side.
Shikoku has a horse that walks the crossroads with no head.
Okayama and Kumamoto have the head, hanging in a hackberry tree, neighing at passers-by.
Fukuoka and Yamaguchi have the leg.
Body. Head. Leg.
The tradition distributed one horse across western Japan like the relics of a saint — and each region's piece kept the animal's signature behaviour.
The body carries. The head calls. The leg kicks.
Nothing else got partitioned this way
Not the fox. Not the cat. Not the tanuki. Not even the human dead.
Every other creature in this collection arrives whole, wherever it arrives.
And I think the reason is worth stating plainly.
The horse was the era's one large animal that every villager knew by part.
You knew the flank, because you walked beside it at the plough all day. You knew the head, because you were at the bit, close, putting the bridle on. You knew the hoof, because you held it up between your knees for the farrier, or you watched somebody do it.
Nobody experienced a working horse as a single unified silhouette. You experienced it as a series of parts at close range, each with its own weight and hazard and smell.
So its haunting arrived pre-dismembered — by familiarity, not by violence.
The horse yokai of western Japan are what happens when the animal you know best is an animal you have only ever met one section at a time.

- The kick; in one telling, a tanuki's ten-foot conjuration.

- Completes the partitioned horse: body in Shikoku, head in western trees, leg here — one animal distributed like a saint's relics.
- The horse was known by part — plow, bit, farrier — so its haunting arrived pre-dismembered.
Overview
At night, from a tree branch — or from the wooden slats of a fence or hedge — hangs a horse's leg. "Those who approach carelessly will be kicked" [ja-uma-no-ashi]. That is the entire fauna: a leg, waiting, with follow-through.
The record
- Fukuoka (Kurazuka): a tanuki conjured "an approximately 10-foot horse's leg to trick travelers at midnight" [ja-uma-no-ashi] — the trickster attribution, as the possession-map predicts for Kyūshū's margins.
- Yamaguchi (Iwamura Kaidanroku): the leg "suddenly protruding from a fence during rainy nights" [ja-uma-no-ashi] — recorded in a proper Edo horror collection.
- The naturalist floor: branches protruding from fences and hedges in the dark [ja-uma-no-ashi] — the shape a wet bough makes when the lantern swings.
The reading
The horse-fragment set completes: body (Shikoku), head (west/north), leg (Fukuoka/Yamaguchi) — the tradition has distributed one horse across western Japan like relics of a saint, each region's piece keeping the animal's signature behavior (the body carries, the head calls, the leg kicks). No other creature in the tradition was partitioned this way — not the fox, not the cat, not even the human dead — and the reason is worth stating on the variant-map page: the horse was the era's one large animal that every villager knew by part — flank at the plow, head at the bit, hoof at the farrier — so its haunting arrived pre-dismembered by familiarity. The naturalist floor (a branch in the dark) does for the leg what pareidolia did for the heikegani: the kernel is real, the species is supplied by the mind's inventory.
