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.
Over a wall — and higher than the wall — an enormous woman in a kimono leans down and laughs at you.
Kerakera. That's the sound, and that's the name. A cackle.
She doesn't attack. She doesn't follow. She looks over the wall at whoever is passing in the street below, and she finds them funny, and she is far too big.
Sekien's caption reaches for elegance
His 1781 text does something interesting: it dresses the image in Chinese literary clothes.
He invokes the famous beauty of Song Yu's neighbour — the woman whose single smile from the top of a wall was said to have bewitched an entire city.
And then he glosses his giantess as, perhaps, "the spirit of a courtesan who overturned her crimson lips and led many astray."
Which is the entry in one line: a seductive smile, posthumously inflated to the size of the damage it did.
She isn't big because giants are frightening. She's big because that's how much of a man's life a smile from the right window could take, and the picture is rendering the loss at scale.
Same district as the faceless courtesan with the hair, the same accounting of what the pleasure quarter cost people, and the same instinct: the quarter generated monsters about longing, and every one of them is a woman.
She isn't only Sekien's
Worth noting, because it's rare in this stretch of the catalog.
There's a separate print — from a different work entirely — showing a severed woman's head laughing, captioned to the effect of the woman's head laughs kerakera; how dreadful.
Which means the laughing-woman apparition was circulating outside Sekien's invention workshop. He may have refined and literary-fied something that was already in the air rather than manufacturing it whole.
The Tosa region has its own relative too — a laughing woman collected in the field, in Kōchi, with the same vocal signature. The literary one and the field-recorded one, side by side.
The laughter file
There's a small genre here that only becomes visible once you have three members.
The hairy river-imp of Kyushu whose giggle is fatal if you laugh back. The tengu's laughter rolling down an empty mountain. And the kerakera-onna, laughing over a wall at a man in the street.
Laughter without a knowable mouth is its own particular horror, and it's a different thing from a scream. A scream tells you something has gone wrong somewhere. Laughter tells you something is going right, for somebody, and it concerns you.
The modern layer adds that her laugh is audible only to its victim, and that the weak-willed can lose consciousness from the sound. That's post-war embroidery and it should carry its date — but it's a good addition, because it does the one thing that makes this creature worse.
If only you can hear it, then everyone around you is watching a man on a street react to nothing.

Overview
Over the wall, higher than the wall, a giant woman in a kimono leans and laughs — kerakera, the cackle — at whoever passes. Sekien's caption (1781) reaches for Chinese elegance: the beauty of Song Yu's neighbor, whose single smile from atop the wall "bewitched the whole city of Yangcheng" — and glosses his giantess as perhaps "the spirit of a courtesan who overturned her crimson lips and led many astray" [ja-kerakera], caption via Inada/Tanaka 1992. The seductive smile, posthumously inflated to the size of its damage.
The record
- The parallel image: the Heike Bakemono Taiji print shows a woman's severed head cackling — captioned "the woman's head laughs kerakera — how dreadful" [ja-kerakera], image record — evidence the laughing-woman apparition circulated beyond Sekien's invention-workshop.
- The modern characterization: the laughter is "audible only to its victim," and the weak-willed can lose consciousness from the sound [ja-kerakera-2] — a post-Shōwa layer, labeled as such.
- The Tosa relative: Kōchi's warai-onna shares the vocal signature [ja-kerakera-2] — the field-recorded laugher beside Sekien's literary one.
- The laughter file: hyōsube's fatal giggle, tengu-warai's mountain laughter, now the kerakera-onna — laughter without a knowable mouth is its own small genre.
