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.
On rainy nights in Okayama, something soft and dog-like presses through a walker's legs.
It brushes the shins. It tangles the stride. You nearly trip.
And it does nothing else.
That's the entire creature
No bite. No curse. No fever, no missing time, no bargain, no toll.
The sunekosuri — "shin-brusher" — is the night road's cat at your ankles. A yokai whose complete portfolio is being underfoot.
I find it genuinely charming that a tradition full of drowned women and severed heads made room for a thing that gets in your way when it's raining.
It has a rougher sibling: the sunekkorogashi, the "shin-toppler," which pulls at legs and causes falls.
Same event, intent dialled up one notch.
The tradition localizes it to Ibara, near the Iryō-dō shrine, and describes it as dog-formed.
And then Mizuki drew it as a cat
Here's why this small, harmless creature is one of the most important entries in the whole collection.
Mizuki Shigeru — the man who revived Japanese yokai for the modern world — drew the sunekosuri as a rolled-up cat.
The 2018 anime followed his design.
And researchers have suggested something remarkable: Mizuki's cat design influenced how people recall their alleged encounters.
People who report having felt something brush their legs on a rainy night in Okayama now remember a cat.
The record says dog.
The reviver's pen edited memory itself
That's the finding, and it's the sharpest specimen of a problem this collection keeps circling.
It's one thing for an artist to popularize a creature. It's another for the artwork to reach backwards into testimony and change what witnesses believe they experienced.
But that's what appears to have happened. A drawing, published, animated, and seen by tens of millions, overwrote the sensory memory of the thing it was depicting.
Not "here's what people say it looks like."
"Here's what people now remember feeling."
Which is why provenance matters
This is the argument for doing the boring work — for tracking which detail came from a 1935 dictionary and which came from a 1960s manga, and saying so.
Not pedantry. Not debunking for its own sake.
Because depiction rewrites testimony.
Once an image is famous enough, it stops describing the belief and starts generating it — and the generation runs backwards, into the memories of people who were there before the drawing existed.
The sunekosuri is a tiny, kind, unthreatening yokai that brushes your shins in the rain.
It's also the single best piece of evidence in this collection for why the sourcing has to be honest.
How to draw it
There's only one correct answer, and it's the entry's whole argument as an image.
Draw both.
The dog — which is the record.
The cat — which is the memory.
Label them.
(It's since become "Scampuss" in a video game, and is by all accounts beloved. The domestication arc completes itself: from a thing in the dark, to a picture, to a memory, to a pet.)

Overview
On rainy Okayama nights, something soft and dog-like presses through a walker's legs — brushing the shins, tangling the stride — and does nothing else [wikipedia-sunekosuri], per a 1935 yōkai dictionary. The sunekosuri is the night road's cat-at-your-ankles: a yokai whose entire portfolio is being underfoot. Its rougher sibling, the sunekkorogashi ("shin-toppler"), pulls legs and causes falls [wikipedia-sunekosuri] — the same event with intent dialed up one notch.
The record
- Okayama; Ibara's tradition localizes it near the Iryō-dō shrine, dog-formed [wikipedia-sunekosuri].
- The design-feedback finding (the entry's real value): Mizuki drew it as a rolled-up cat; the 2018 anime followed; and "researchers suggest[] Mizuki's cat design influenced how people recall their alleged encounters" [wikipedia-sunekosuri]. The reviver's pen editing memory itself — the strongest single documentation of the feedback loop the Mizuki dossier describes: not just which yokai are famous, but what people remember brushing their legs.
- Nioh 2's beloved "Scampuss" completes the domestication arc [wikipedia-sunekosuri].
The reading
The night-road ecology gains its comic-relief understory — and the methodology gains its sharpest specimen: provenance discipline matters because depiction rewrites testimony. One sentence for the About page, sourced here.
