The claim, examined
The abandonment that mostly didn't happen
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.
There's a dark idea attached to Japanese folklore that turns up constantly, and it needs the finding stated first.
Ubasute — carrying an aged parent up a mountain and leaving them there to die.
It is one of the most cited facts about pre-modern Japan. It underpins the darkest theory about the mountain-witch. And it appears in a Palme d'Or-winning film that a great many people took as history.
The scholarly assessment:
Ubasute "is the subject of legend, but does not seem ever to have been a common custom."
The abandonment was a story Japan told, not a thing Japan routinely did.
And Yanagita himself traced the tale-type back to Indian Buddhist mythology — transmission, not practice. The story arrived. It didn't grow out of anything anyone here was doing.
And the central tale is about the opposite of abandonment
This is what makes the misreading so strange, because the most famous version completely inverts the premise.
A son carries his old mother up the mountain.
And all the way up, she is breaking twigs.
He notices. He asks why.
And she tells him: *so you can find your way home.*
She is being carried to her death by her son, and what she is doing with her hands is marking his route back.
The endings people don't quote
In the standard continuations, he can't go through with it.
He carries her back down and hides her in the house.
And later — when the province's lord sets an impossible riddle, or a neighbouring power demands the answer to some unanswerable question, and the village faces ruin for failing — it is her knowledge that solves it.
The old woman's wisdom saves everyone, and the practice is abolished by the lord who learns where the answer came from.
That is the tale-type. Not an abandonment story. A story about why you don't abandon people — argued by demonstration, with a riddle.
The mountain is real, though
Ubasute-yama — Mount Kamuriki, in Chikuma, Nagano.
The legend's geographic anchor. It's famous for moon-viewing, and there's a long poetic tradition attached to watching the moon from there, tangled up with the story.
And the modern layer did the damage
Fukazawa's novel *The Ballad of Narayama (1956), and the 1983 film* that won the Palme d'Or.
Both are extraordinary. Both present the practice as an established village custom, systematically observed.
And that premise — a modern novel's premise — got retro-read as ethnography by audiences worldwide.
It is now, for a great many people outside Japan, simply a thing they know about Japanese history.
Which cuts both ways
The provenance discipline that runs through this whole collection — checking when a claim first appears, and who made it, and whether anything corroborates it — is usually applied to monsters.
It applies to atrocities too.
And here it acquits.
A culture has been widely believed to have systematically abandoned its elderly, on the strength of a folktale of foreign origin whose actual moral is the reverse, plus a twentieth-century novel.
That is worth getting right.
What it means for the mountain-witch
There's a theory that the yamauba — the mountain-crone who takes in travellers and eats them — is the folk memory of abandoned old women.
That theory now carries its audit: she cannot be the memory of a common custom that wasn't one.
She may still be the memory of the story — folklore begetting folklore, an imported tale about mountains and old women generating a mountain woman.
Which is subtler, and I think better, and it's the version that survives checking.

- Behavior
- Not a creature but a legend audited: the tale of old women carried up the mountain and abandoned — the darkest theory behind the yamauba — which scholarship finds was a story Japan told, not a thing Japan routinely did.
- Powers
- The story's force, which is the opposite of its premise: carried to her death, the mother breaks twigs the whole way up — so her son can find his way home.
- Oddities
- Yanagita traced the tale-type to Indian Buddhist mythology — transmission, not practice; in the standard continuations the son cannot go through with it, hides her at home, and her elder's wisdom saves the village.
- The custom-as-fact impression is largely modern: a 1956 novel and its Palme d'Or film retro-read as ethnography.
- The provenance discipline this catalog applies to monsters applies to atrocities too — and here it acquits.
Overview
The darkest theory in the tradition — that the yamauba is the memory of old women abandoned in the mountains — rests on ubasute, and the scholarship's finding must lead the entry: ubasute "is the subject of legend, but... does not seem ever to have been a common custom" [wikipedia-ubasute], per Kodansha. The abandonment was a story Japan told, not a thing Japan routinely did — and Yanagita himself traced the tale-type to Indian Buddhist mythology, transmission rather than practice [wikipedia-ubasute].
The central tale (and it's about the opposite of abandonment)
A son carries his old mother up the mountain. All the way, she breaks twigs — and when he wonders why, she tells him: so you can find your way home. Marked for his return by the woman he is carrying to her death [wikipedia-ubasute]. The tale-type's whole force is filial love indicted by its own frame; in the standard continuations the son cannot go through with it, brings her home hidden, and her elder's wisdom later saves the village (the solve-the-impossible-tasks variants — verify tale-numbers next pass).
The record
- The mountain: Ubasute-yama (Mt. Kamuriki, Chikuma, Nagano) — the legend's geographic anchor, moon-viewing famous [wikipedia-ubasute].
- The modern layer: Fukazawa's Ballad of Narayama (1956) and the Palme-d'Or 1983 film fixed the custom-as-fact impression in the world's mind [wikipedia-ubasute] — a modern novel's premise retro-read as ethnography; the tradition's provenance discipline applies to atrocities too, and here it acquits.
Why it matters for the yamauba
The yamauba entry's "ubasute theory" now carries its audit: the mountain crone cannot be the memory of a common custom that wasn't one. She may still be the memory of the story — folklore begetting folklore — which is subtler and better.
