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.
This is the shortest good story in Japanese folklore, and it is genuinely perfect. Here it is in full.
An old woman is walking a mountain pass in Amakusa, in Kumamoto, with her grandchildren. It's the Kusazumigoe, a real pass you can still walk. To pass the time — or to keep the children close — she says: you know, long ago an abura-sumashi used to come out around here.
And a voice from the empty pass says:
"I still do."
That's it. That's the whole thing. No description of what happened next, no chase, no moral. Somebody on that road tells a story about a monster in the past tense and the monster corrects their grammar.
What is actually out there
The honest answer is: almost nothing is known, and that's part of the charm.
The name means "oil presser," and the belief attached to it is that it's the ghost of an oil thief — in Amakusa the oil in question would have been pressed from tea seeds — who ran off into the woods with what he'd taken and never came back out. That puts him in a small club. Japanese folklore has at least three separate oil thieves who were turned into monsters as punishment, one becoming a burning old woman, one a flaming monk's head, and this one simply exiled to a mountain road forever. Lamp oil was light, and light was expensive, and stealing it apparently got you a sentence with no parole.
As for what he looks like: a squat figure in a straw rain cape with an enormous head like a stone or a potato. But you should know that this picture is mostly modern. It was fixed in the public mind by twentieth-century illustration, and the older record barely describes him at all.
Which is appropriate, because the older record barely needs to. The abura-sumashi is not a shape. He's a voice in the fog on a pass where you had just been reassuring somebody that there was nothing there.

At a glance
- Behavior
- Haunts the Kusazumigoe pass in Amakusa; when a grandmother says one "used to appear here," a voice answers from the empty pass: "I still do!"
- Powers
- Comedic timing — the entire attested folklore is one perfectly delivered jump-scare.
- Weaknesses
- None recorded.
- Oddities
- The ghost of an oil thief fled to the mountains — the oil-thief family's comic relief, exiled rather than burning.
- The squat straw-cape, potato-head look is largely Mizuki's modern design; the older record is mostly the voice.
Overview
On the Kusazumigoe pass in Amakusa, a grandmother tells her grandchildren: "long ago, an abura-sumashi used to appear here" — and a voice answers from the empty pass: "I still do!" That perfectly timed punchline is essentially the entire attested folklore of the abura-sumashi — and it's enough: the yokai as jump-scare with impeccable comedic instincts.
Lore
- Region: Amakusa, Kumamoto — a genuinely local spirit [wikipedia-aburasumashi].
- Form: squat, straw rain-coat, a great stony/potato-like head — an appearance largely fixed by Mizuki's modern depictions [wikipedia-aburasumashi]; the older record is mostly the voice.
- Origin belief: the ghost of an oil thief who fled into the woods — tea-seed oil in Amakusa's case; oil-theft-becomes-yokai is now a three-entry pattern in this bestiary (ubagabi's shrine oil, sōgenbi's temple oil, abura-sumashi's pressed oil) [wikipedia-aburasumashi]. Pre-electric lamp oil was wealth; stealing light made ghosts.
The trilogy
The oil-thief trilogy belongs together: three regions, three punishments (fire, fire, mountain exile) for the same crime. The abura-sumashi is its comic relief.
