The picture, plainly
Somebody has been licking your ceiling
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.
Those brown stains high on an old ceiling — the ones too high for any hand to have made — have an author.
The tenjōname, the ceiling-licker. A tall, thin creature with an enormous tongue, working the rafters by night.
And the record is specific about when: particularly in the cold months, when light cannot reach all the way to the ceiling and casts weird shadows.
It's the altitude partner to a better-known monster
There's a creature that licks the scum in an unscrubbed bathtub — the akaname — which appears where the household has stopped cleaning.
The pairing is neat and it's the entry's whole shape:
One licks where you won't clean.
The other licks where you can't.
Because that's the honest situation with an old ceiling. Nobody is neglecting it. It's four metres up, over a room with no ladder in it, and it has been slowly staining since before you were born.
And Sekien is quoting a book about house-building
The provenance here is fully traceable and it's one of the best in the collection.
Sekien, 1784. And his source is essay 55 of the *Tsurezuregusa*, Yoshida Kenkō's fourteenth-century essays.
Which is a piece of house-building advice.
Kenkō warns that too high a ceiling makes winters cold and lamplight dark.
That's it. That's the source. A practical architectural note from the 1330s about how not to design a room.
And Sekien read it, and thought about what a draught-chilled, shadow-stained, too-tall ceiling feels like at night — and gave it a creature.
The scholarship is blunt: older folktales about it do not exist. His image is the first.
One book, both ends of the spectrum
Here's what makes that satisfying.
The same *Tsurezuregusa contains, at essay 89, a genuine folk report — the account of the nekomata*, the cat-monster of the mountains, which people said ate humans. A real fourteenth-century belief, written down.
And at essay 55, a building tip that Sekien turned into an invented monster four hundred years later.
One book. Attested folklore at one end, manufactured folklore at the other.
If you wanted a single object to explain why provenance work matters in this tradition, it's Kenkō's essay collection.
The domestic suite is complete
Line up the household monsters and you get a full set of rooms.
The bath — the scum-licker.
The altar — the lacquered corpse that climbs out when the doors are left open.
The paper screens — the eyes that fill every hole in the torn shōji.
The damp — the ball of hair that appears in a neglected corner.
And the ceiling — this one.
A complete household of consequences.
And nearly all of them are Sekien's editorial cartoons rather than village belief — which doesn't diminish them. It relocates them.
These aren't monsters. They're an argument about how to keep a house, made in pictures, by a man who had clearly thought hard about what a badly kept room feels like at night.
Edo's imagined housekeepers were its actual conscience.

- Behavior
- Licks the high rafters by night with an enormous tongue, leaving the brown stains no hand could reach.
- Powers
- Altitude — it cleans (or marks) where you can't.
- Weaknesses
- A lower ceiling, per the 14th-century essay it was built from.
- Oddities
- Invented by Sekien from a Tsurezuregusa house-building tip: high ceilings are cold and dark, so he gave the chill a creature.
- The same book both attested the real nekomata and seeded this invention — one source, both ends of the provenance spectrum.
Overview
Those brown stains high on an old ceiling — too high for any hand — have an author: the tenjōname, a tall yokai with an enormous tongue, licking the rafters by night, "particularly in the cold months when light cannot reach all the way to ceiling and casts weird shadows" [search-2026-07-25]. The akaname's altitude-partner: one licks where you won't clean, the other where you can't.
The provenance (a literary pun, fully traced)
Pure Sekien (1784), and his source is documented: Tsurezuregusa, essay 55 — Yoshida Kenkō's advice on house-building, warning that too high a ceiling makes winters cold and lamplight dark [search-2026-07-25], per the Semiotic Review analysis; Sekien references the essay in his caption. Sekien took a 14th-century architecture tip and gave the draft-chilled, shadow-stained tall ceiling a creature — "older folktales about it do not exist"; his image is the first [search-2026-07-25]. The same Tsurezuregusa that attested the mountain nekomata thus also seeded an invented yokai four centuries later: one book, both ends of the provenance spectrum.
The reading
The domestic-discipline suite closes its roster: bath (akaname), altar (nuribotoke), screens (mokumokuren), damp (keukegen), ceiling (tenjōname) — a complete household of consequences, most of them Sekien's editorial cartoons, all of them now labeled as what they are. The suite page's thesis: Edo's imagined housekeepers were its actual conscience.
