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.
Japanese folklore is full of terrifying old women. The mountain hag who feeds travelers and then eats them. The crone at the river of the dead who strips the clothes off arriving souls. The one in the lonely house at Kurozuka with a room nobody is allowed to open.
Arikura-no-baba is the same figure, in the same landscape, with one difference that changes everything: her village trusted her.
The hag of Takayama
She lived in the mountains around Takayama, in Gifu, and she was known for healing, for divination, and for weather-work. An old woman living apart from everyone, with abilities the village couldn't match and didn't fully understand, and could nonetheless go and ask for.
Two things she did are on the record, and they are both wonderful.
She talked a volcano down. The mountain had been rumbling for seven days — which, in a region that lives on volcanic ground, means a village waiting to find out whether it still exists next week. Arikura-no-baba prayed, and the eruption stopped.
She cooled a hot spring by throwing a horse's hoof into it. The onsen was too hot. She threw in a hoof. It went cold.
That second one is, frankly, magnificent. It is not a moral, or a warning, or a tragedy. It's an old woman performing an unexplained piece of thermal maintenance on the local bath with an animal part, and the village remembering it for centuries.
Why she matters more than she looks
Put her beside the rest of the hags and something becomes obvious.
Most of the frightening old women in this tradition are what happens to women's power when it has no institution behind it. The mountain hag is feared because she's outside the village and answers to nobody. The one at Kurozuka is a household servant whose life went catastrophically wrong. Their power is real and it is treated as contamination.
Arikura-no-baba has exactly the same power and gets read the other way. She's described as a reclusive mountain woman with spiritual insight who may bless or curse depending on how she's treated — and the point is that her village generally chose to treat her well, and generally got blessed.
Now look at what she was actually doing in those two stories. Stopping an eruption. Regulating a hot spring. That is disaster management and public utilities. Elsewhere in Japan those jobs belonged to the state and its institutions — a great monk sealing a mountain, a shrine maintaining the stone that pins the earthquake fish underground, priesthoods and rituals and budgets.
In Takayama it was one old woman who lived up the hill, working alone, unpaid.
That's the entry's real content. The tradition was perfectly capable of imagining female mountain power as municipal infrastructure rather than as a threat. It just didn't do it very often.
A candid note: the accessible record on her is thin — a short account and not much else. Even the meaning of her name, the "ant-saddle" hag, isn't clearly explained anywhere reachable, and neither the mountain nor the hot spring is reliably named. Nothing above has been filled in past what survives.

Overview
Takayama's resident wonder-worker: Arikura-no-baba — "the ant-saddle hag" — an old woman of supernatural powers: healing, divination, weather-work [en-arikura]. The two deeds on record are the entry's substance:
- She stopped a mountain's eruption by prayer after seven days of rumbling [en-arikura] — a hag performing, solo and unpaid, the service the state maintained Kūkai and the kaname-ishi for.
- She turned an onsen cold by throwing a horse's hoof into it [en-arikura] — the tradition's strangest utility adjustment, and a horse-part cameo for the fragment-family (the hoof as thermal valve).
The reading
The baba shelf's counterweight: the tradition's hags mostly embody what happens to women's power outside institutions (the onibaba manufactured by an errand, the jakotsubaba built from slang) — Arikura-no-baba is the same figure trusted: a village keeping the memory of an old woman whose competence ran to geology, read as "a reclusive yamamba with spiritual insight" who "may bless or curse depending on how she is treated" [en-arikura] — the yamauba's dual ledger with the benevolent column, for once, the longer one. She belongs beside the yama-no-kami's okoze-diplomacy as evidence the tradition could imagine mountain-female power as municipal infrastructure.
