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.
A small boy is walking through the wet dusk. He's wearing an umbrella-hat far too big for him — the wide woven kind, tipped down over his eyes — and carrying a paper lantern.
Wherever he goes, it rains.
That's the amefurikozō, the rain boy, and he is one of the most likeable things in the catalog because of what he turns out to be. He isn't a rain god. He isn't even a rain spirit, exactly.
He's staff.
Toriyama Sekien's caption, when he drew him in 1779, identifies the boy as the child attendant of the Chinese rain deity. Not the one making the weather — the one running the errands for the one making the weather. The rain god's junior employee, out doing the rounds in bad conditions with a hat and a lamp, because that's the job.
The joke Sekien was making
Scholars point out the wordplay, and once you see it the whole picture is funnier. The god's name and the boy's title sit in the same construction as adult and child. The image is essentially: a child employed by an adult, sent out in the rain.
Sekien did this constantly. A great many of his creatures are puns that grew bodies, and the amefurikozō is one of the gentlest — an entire supernatural being invented out of the observation that somebody junior always gets sent out in the weather.
Edo readers took to him immediately. He became stock comic staff in the cheap illustrated storybooks of the period, turning up alongside the tōfu-kozō — the little spirit boy who does nothing but carry a block of tofu — as background characters, mascots, comic relief. A print from 1792 gives him a single eye and a bamboo hat on rainy nights.
Which is worth pausing on: the Edo period was doing mascot-ification of its own monsters two hundred years before the modern era got the credit for it.
The modern additions
You'll also read that if you steal his umbrella it fuses to your head and can never be removed, and that the rain follows his moods.
Those are later. They're good — the fused umbrella is a genuinely nasty image — but they're not in the old record, and it's worth knowing which parts of a creature you're looking at.
The weather department
He has colleagues, and together they make up something close to a complete staff list for Japanese weather.
There's the ameonna, the rain woman, whom Sekien drew licking rainwater off her hand. There's the hiyoribō, the fair-weather monk, who works the other shift and brings clear skies.
And here is the detail that ties it to something children in Japan still do. Sekien claimed the hiyoribō is the ancestor of the teru-teru-bōzu — the little white cloth doll you hang in the window to ask for good weather tomorrow, which Japanese kids make to this day before a school trip.
If Sekien was right, that small ghost hanging in the window is a yokai's grandchild.
Field guide
At a glance
- Behavior
- Trots through wet dusk under an oversized umbrella-hat, lantern in hand — where he walks, rain falls.
- Powers
- Rain delivery as an errand: Sekien's caption makes him the child attendant of the Chinese rain deity, doing his rounds.
- Weaknesses
- None classical; the umbrella-theft curse (it fuses to the thief) is modern accretion, labeled.
- Oddities
- Edo comics used him as stock staff long before Mizuki — mascot-ification is older than it looks.
- Sekien's own note claims the teru-teru-bōzu descends from the weather-monk — making the paper charm in the window a yokai's grandchild.
Overview
A small boy under an oversized umbrella-hat, out in the wet dusk, lantern in hand — where he walks, rain falls. The amefurikozō is weather with a servant's job description: Sekien's caption makes him the child attendant (jidō) of Ushi, the Chinese rain deity — the rain god's errand boy, doing his rounds [sekien-1779]; [wikipedia-amefurikozo].
The layers
- Sekien (1779): plate + caption with the Ushi allusion; scholars note the wordplay (Ushi/adult vs jidō/child — the yokai as "a child employed by an adult") [wikipedia-amefurikozo].
- Edo comics: in kibyōshi the amefurikozō is stock comic staff, alongside the tōfu-kozō; a 1792 print gives him one eye and a bamboo hat on rainy nights [wikipedia-amefurikozo] — the Edo period's own mascot-ification, long before Mizuki.
- Modern accretion: steal his umbrella and it fuses to you; rain follows his moods [wikipedia-amefurikozo] — label as modern.
Reading
With ameonna (the rain woman), hiyoribō (the fair-weather monk, Sekien 1779), and the teru-teru-bōzu charm children still hang, Japan's weather folklore forms a complete cast of rain-management personnel — and Sekien's own note claims the teru-teru-bōzu as the hiyoribō's descendant, which would make the paper charm on the window a yokai's grandchild.
