Yamauba

The mountain's old woman.

Golden-white unkempt hair. A filthy tattered kimono.

And in the darker tellings — a second mouth, hidden under the hair on top of her head.

She is two things, and neither cancels the other

The devourer. She offers shelter to merchants and ox-drivers coming over the pass. She feeds them. And then, in the night, she comes.

The chase-and-escape tales — where the traveller flees and she pursues and is finally burned — are the fairy-tale layer, and they are very old.

The mother. She raised Kintarō.

The red-skinned super-child of Mount Ashigara, who wrestled bears, who grew up into the real-titled warrior Sakata no Kintoki — one of the Four Heavenly Kings, Raikō's guard.

Which closes a loop that I don't think gets pointed out enough:

The yamauba's foster son helped kill Shuten-dōji.

The mountain-witch raised the boy who went up Mount Ōe with the demon-slaying squad. Japan's most famous man-eating crone is, by the same tradition, the reason its most famous demon died.

And the Noh play is something else entirely

Before the fairy tales flatten her, it's worth knowing what the stage made of her.

In the Noh Yamanba, she is the eternal caretaker of the mountains — a near-cosmic figure who circles the peaks with the seasons, endlessly, doing the work of the mountain itself.

A dancer who has made her career performing a "yamauba dance" meets the real one, and the real one is not a monster at all. She is old, and tired, and vast, and still walking.

The Noh yamauba is philosophical, not monstrous, and it is one of the great plays in the repertoire.

The moral auditor

The other half of her folk role: she grants fortune to the kind and curses the cruel.

Which is the mountain functioning as a test. Meet an old woman on a pass and what happens next depends on what you do — and both outcomes are on the record.

That's the same structure as the escorting wolf, the growing monk, the burden that turns to gold. The mountain is not hostile. It is evaluative.

One theory, and its audit

There's a standard scholarly reading that the yamauba is the memory of abandoned elderly women — the ubasute practice, remembered as a monster.

And it needs its correction attached, because the correction is well established: ubasute does not appear ever to have been a common custom. It's a legend, and Yanagita traced the tale-type to Indian Buddhist mythology, and the central version of the story is about a son who can't go through with it.

So she cannot be the memory of a widespread practice, because there wasn't one.

She may still be the memory of the story — folklore begetting folklore.

Which is subtler and, I think, better.

And art history knew she was double

The great ukiyo-e genre is "Yamauba and Kintarō" — and Utamaro made a series of them.

They are tender. A wild-haired woman with a plump red child: nursing him, combing his hair, watching him play. Domestic scenes, drawn with enormous affection, of the most feared figure in the mountains.

The same artist. The same decade. The same woman who eats travellers.

The dual nature, worked out in art history itself — and nobody involved seems to have found it a contradiction.
