The object, plainly
The jar that pours forever
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.
A big storage jar, with eyes and a nose and a mouth.
And Sekien's caption, which is the only entirely happy caption in his entire body of work:
The water pours without end. The drink stays as it was. An auspicious omen.
That's the kameosa. It never runs dry. That's all it does, and it does it forever.
Where he put it
Position matters here, and it's the reason this small cheerful jar is worth an entry.
Sekien placed the kameosa as the very last yokai in his final catalog.
Think about what that volume is. It's the collection of awakened household objects — a parade of tools that were used up, thrown out, and came back resentful. Sandals that walk out on you. A lute complaining that nobody plays it. A quiver whose glory has been forgotten. A screen that became a voyeur. Object after object with a grievance.
And he ends it on a jar that gives.
That is as close to a thesis statement as the great cataloguer ever left. The objects are all watching, all of them, the whole time — and what they become is how you kept them.
It's the same logic as the poverty god who turns into a fortune god in a household that honours him, and the foot through the ceiling that becomes a household guardian when it's washed with respect. Treat the thing well and the thing pours.
The joke
There's a theory about the name that I hope is true.
Kameosa was the artist-name of Koikawa Harumachi — a pioneer of Edo comic fiction, and Sekien's own student.
Harumachi was, by reputation, an enthusiastic drinker.
So the plate may be a fond dig at his pupil: a jar of drink that never empties, named after the man who behaved as though one existed.
Which would mean that the final creature in Sekien's final catalog — the last figure in the parade, the closing image of the whole enterprise — is his student, drawn as a bottomless cup.
The teacher's last word on the world of monsters is a toast.
On provenance
Honestly: no historical folklore behind it. It's a created yokai, and the later biography attached to it — a hundred-year-old jar awakening in the usual way — is standard retrofitting.
Which doesn't cost it anything here. Nobody is claiming an ancient tradition of inexhaustible pots. What's real is the gesture: a man who spent his career cataloguing the resentments of discarded things, choosing to finish with a blessing.

- Oddities
- Sekien placed it last in his final catalog — the parade of resentful objects ends on one that gives: the closest thing the great cataloguer left to a thesis statement.
- "Kameosa" was the artist-name of his student Harumachi, famous for his thirst — the last yokai in the canon may be a teacher's toast to a drinking buddy.
Overview
A great jar with eyes, nose, and mouth — and Sekien's caption makes it the catalog's one blessing: "waters pour without end, drinks remain unchanged — an auspicious omen" [sekien-tsurezure]; [ja-kameosa]. The inexhaustible vessel: fortune with a face.
The record
- Position matters: the kameosa is placed as the final yokai in the collection — the Tsurezure Bukuro's parade of resentful objects ends on an object that gives [ja-kameosa]. Sekien closing his last catalog with a full cup.
- The in-joke theory: "Kameosa" was the artist-name of Koikawa Harumachi, Sekien's student — the plate possibly a fond jab at Harumachi's famous thirst [ja-kameosa]. A yokai that doubles as a teacher's toast to his pupil.
- Verdict: created yokai, "without historical folklore precedent" [ja-kameosa]; later readings add the standard aged-object biography.
The reading
The tsukumogami doctrine's grace note. The doctrine's engine is grievance — tools discarded after service, returning with claims. The kameosa is the same animism running in credit instead of debt: the vessel kept, used, and honored pours forever — the binbōgami conversion-legend's logic (treat even poverty with respect and it becomes wealth) stated as pottery. That Sekien ends his final catalog here is the closest thing the great cataloguer left to a thesis statement: the objects are watching; what they become is how you kept them. And if the Harumachi joke is true, the last yokai in the canon is a drinking buddy — the delight-register entry par excellence.
