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.
There is a monk in your privy, and birds are coming out of his mouth.
That's Sekien's plate from 1779, and it is one of the strangest images in his whole body of work. A robed figure crouched in the toilet, mouth open, cuckoos pouring out of it.
The password
The defence is calendrical, and the whole thing collapses into a joke that I find genuinely delightful.
On New Year's Eve, you recite: "ganbari-nyūdō hototogisu."
Say it once, on that night, and you're clear of him for the year.
Except — and this is the part — the incantation itself was considered inauspicious even to recall. Bringing the phrase to mind was bad luck.
So you have a protective spell that you must remember once a year, on the correct night, and which you should otherwise never think about.
A password that is unlucky to know. Folk religion's most elegant double bind, and the only self-defeating charm in the collection.
The bird taboo underneath
There's a real folk belief under the picture, and it's the reason the birds are there.
Hearing the cry of the hototogisu — the lesser cuckoo — while you were in the privy portended misfortune.
That's a genuine taboo, and look at how oddly specific it is. Not hearing the bird. Hearing it from in there. It's a rule about coincidence — the calendar of your body intersecting with the calendar of the birds — and it must have produced a small unpleasant jolt for anyone who knew it, several times a summer, for centuries.
And a Chinese god smuggled in by homophone
Now the mechanism, which is pure Sekien.
The Japanese for that cuckoo is written 郭公. And there is a Chinese privy deity whose name is written 郭登 — Guo Deng, rendered in Japanese as Kakutō — titled as a general who dispenses misfortune.
The characters echo. The sounds are close.
So the bird taboo and the imported toilet god fold into each other, and Sekien draws the result literally: a privy deity whose mouth produces cuckoos, because phonetically the privy god is the cuckoo.
It's the same trick he plays across his catalogs — a pun, drawn as anatomy. And it's also how a Chinese deity ended up in Japanese bathrooms: not through doctrine or worship, but by sounding like a bird.
Why the toilet, always
Worth stepping back, because this station keeps getting staffed.
In a pre-modern Japanese house the privy was the most liminal room there was. It sat at the edge of the building or outside it. It was over a pit. It was dark. And it was the one place you went alone, at night, no matter how frightened you were, because there was no alternative.
So the tradition put things there, continuously, for centuries. The bird-mouthed monk in 1779. The scraping visitor waiting at the outhouse in Ehime. And then, in the twentieth century, Hanako-san in the third stall of a school bathroom.
Same station. Three hundred years apart. The building changed; the loneliness didn't.

Overview
A monk-figure in the privy, spewing birds from his mouth — Sekien, Konjaku Gazu Zoku Hyakki (1779) [sekien-1779]; [ja-kanbari]. The defense is calendrical and verbal: on New Year's Eve, recite "ganbari-nyūdō hototogisu" and you avoid him for the year — though the incantation itself "was considered inauspicious to merely recall" [ja-kanbari]: a protective spell you're better off not remembering — the tradition's only self-defeating amulet.
The record
- The cuckoo taboo: hearing the hototogisu's cry while in the privy portended misfortune [ja-kanbari] — real folk taboo, the substrate under Sekien's picture.
- The Chinese privy-god: the cuckoo's kanji 郭公 echoes 郭登 (Guo Deng/Kakutō), the Chinese privy deity titled as a misfortune-granting general [ja-kanbari] — Sekien's bird-spewing mouth is the pun drawn literally: the privy god IS the cuckoo, phonetically.
- Regional forms: Wakayama's setchin-bō; Okayama confusion with the mikoshi-nyūdō; a possible layer from the Chinese giant-demon Yandao conflated with privy deities [ja-kanbari].
The reading
The toilet file's Edo anchor. The privy is the pre-modern house's most liminal room — over a pit, at the building's edge, visited alone at night — and the tradition staffed it accordingly, from this bird-mouthed monk to Hanako-san's third stall: same station, three centuries apart. The entry's treasures are both protocols: a taboo triggered by birdsong overheard at the wrong moment (the calendar of the body meeting the calendar of the birds), and the once-a-year password that is itself unlucky to know — folk religion's most elegant double-bind, worth a box on the-rules page. And underneath, the usual import-machinery: a Chinese god smuggled into Japanese bathrooms inside a homophone.
