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.
Kasane was disfigured, and she had money.
A man called Yoemon married her for the second reason and could not get past the first. And in 1647, at the edge of the Kinugawa river, he killed her with a sickle and let the water take her.
Then he remarried.
She came back through the wives
This is what makes the Kasane cycle different from every other revenge ghost in Japan.
She didn't haunt him. She possessed his next wife — speaking through her mouth, naming what he had done, in his own house, out loud.
That wife died.
He married again. She possessed that one too.
And again. And again. Wife after wife of the same household, each one becoming a mouth for the same accusation, until the count reached seven.
And then it moved to the next generation: the seventh wife's daughter was found to be carrying Kasane's spirit — and, underneath it, another one.
The one underneath
Because there had been an earlier killing in that household.
A disfigured child called Suke, put to death before Kasane was ever born into the story, for the same reason: the family could not stand to look at them.
So the daughter is carrying two dead people, and the second one has been waiting longer.
The name 累 — Kasane, Rui — means accumulation. Piling up. Layer on layer, which is exactly what the curse does. It isn't one murder avenged. It's a household's habit, compounding across generations, and every new wife is another sheet on the stack.
The exorcist-priest Yūten was eventually summoned and got them both out. That's the resolution, and it took a saint.
And it's all real property
Here's what stops this being merely a good ghost story.
The graves exist. Kasane's, Suke's, and Kiku's, at Hōzō-ji temple in Jōsō, Ibaraki. You can stand in front of them.
The exorcism is dated to January 1672.
And the site sits about 870 metres from Nakatsuma Station on the Kantō Railway — which makes Kasane, as far as I can tell, the only haunting in Japanese folklore with walking directions from a train platform.
The honest caveat
The main text carrying the story is from around 1690, and it is formally a hagiography of Yūten — an account of the exorcist's heroic deeds.
Scholars are direct about what that means: it reads in part as Buddhist proselytizing, and the horror may be doing promotional work for the priest and his sect.
Which doesn't dissolve it. There are graves, a date, a river, and a place name that stuck. But the version we have was written by people with a reason to make the possession dramatic and the exorcism decisive, and that belongs on the label.
The story went on to become one of the great rakugo pieces, and a century of films. With Oiwa and Okiku, Kasane completes Japan's trio of great vengeful ghosts — three stories in which the ghost is not really a person at all, but injustice, refusing to stop being true.
Field guide
At a glance
- Behavior
- Murdered with a sickle at the river's edge by the husband who married her for money, she possessed wife after wife of his household, speaking accusation through their mouths.
- Powers
- Multigenerational compounding — her name means "accumulation," and the curse carried an earlier victim's grievance folded into hers.
- Weaknesses
- The exorcist-saint Yūten, summoned for the seventh wife's daughter — the cycle's vehicle is formally his hagiography.
- Oddities
- The graves are real and visitable at Hōzō-ji — the tradition's only haunting with walking directions from a train platform (~870 m from Nakatsuma Station).
- The source text may be Buddhist propaganda with a body count; the burials are pinned regardless.
Overview
Kasane was a disfigured woman married for her money by a man named Yoemon, who — revulsion curdling into greed — killed her with a sickle at the edge of the Kinugawa river. She came back. Not once: she possessed wife after wife of her murderer's household, speaking accusation through their mouths, until the seventh wife's daughter carried both Kasane's spirit and an earlier victim's — and the exorcist-saint Yūten was summoned. The Kasane cycle is Edo Japan's great multigenerational curse story, and its graves are real and visitable.
The record
- Primary vehicle: the 17th-century Shiryō Gedatsu Monogatari Kikigaki (c. 1690) — formally a hagiography of Yūten the exorcist; scholars note it reads partly as Buddhist proselytizing literature ("the original text is mainly dedicated to the heroic deeds of Yūten... may have been nothing more than Buddhist propaganda") [search-2026-07-24]; [atlas-obscura]. The legend as sermon with a body count.
- Yet: the graves of Kasane (Rui), Suke, and Kiku exist at Hōzō-ji temple (Jōsō, Ibaraki) [atlas-obscura] — the tale is pinned to real burials, whatever its embellishment.
- The name 累 ("Rui/Kasane" — accumulation) itself reads as piled-up karma: Suke was an earlier disfigured child of the household, killed before Kasane — the curse compounds across generations.
- Ehon Hyaku Monogatari (1841) carries the Kasane plate [ehon-1841]; rakugo's Shinkei Kasane-ga-fuchi (San'yūtei Enchō) and a century of film adaptations carried it forward.
Why it matters
With Oiwa (Yotsuya Kaidan) and Okiku (Sarayashiki), Kasane completes Japan's onryō triad — stories where the yokai is injustice itself persisting. All three need entries; all three have real-world grave/well sites; all three still observe the tradition that productions pay respects before staging them (verify per-case).

Kinugawa fuchi location— second pass [ja-kasane]: the site sits by Hōzōji at Hasui-machi, Jōshū City, Ibaraki, ~870 m from Nakatsuma Station on the Kantō Railway — the tradition's only haunting with walking directions from a train platform; the exorcism dated January 1672 (Rui murdered 1647; Suke killed earlier by the father).
