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.
Over the imperial palace in Kyoto, in the plague year of 1334, a bird circled at night.
It had a human face. A curved beak with saw teeth in it. A snake's body. A wingspan of nearly five metres.
And it called out, in words:
*"Itsumade... itsumade..."*
"Until when? Until when?"
An archer, Oki Jirōzaemon Hiroari, brought it down with a special arrow — which is, beat for beat, what happened a hundred and eighty years earlier when a different archer shot a different monster off the roof of a different emperor's palace. Japan has a recurring civic emergency: something wrong lands on the imperial residence, and a marksman is sent for.
What it was asking
The reading that gives this creature its force is modern, and I'll flag it as modern, but it fits the setting so exactly that it's hard to put down.
The cry is the reproach of the unburied dead.
1334 was an epidemic year, at the end of a period of serious warfare. The corpses of the plague dead and the battlefield dead were not being properly handled. There were too many, and there was no one to do it, and they lay where they were.
Until when?
Not a threat. Not a curse. A question, asked over and over, all night, above the court responsible — by something with a human face, in human words, that nobody can answer.
It may be the quietest devastating thing in this entire tradition. A monster whose whole body is a question the living won't answer, circling the building where the answer would have to come from.
The name is an editor's decision
Here's a provenance detail worth knowing, because it's the benign version of something this collection usually treats as a problem.
The Taiheiki, the fourteenth-century chronicle that records the event, doesn't call it an itsumade. It just calls it a demon bird.
The name itsumade is Sekien's coinage, four centuries later. He took the cry, chose kanji for it, drew the creature, and thereby established it as a distinct being with an identity.
So the monster is medieval and the name is an Edo editorial decision.
Normally that pattern is the beginning of a problem — an artist invents a pedigree, later readers take it as ancient, and the record gets muddled. Here it's the opposite. Sekien didn't fabricate anything. He found a nameless horror in a chronicle and gave it the only name it could possibly have: the thing it was saying.
That's accretion of the good kind. Naming as curation.
There's a variant modern reading, too, that goes further and makes the bird the war-dead themselves, transformed — not asking on their behalf but arriving in person, in avian form, to put the question directly.
Either way it's the same question, and nobody in the palace answered it.

- Circled the plague-year palace nightly in 1334, crying a human phrase: "itsumade, itsumade" — until when? until when?
- Powers
- A five-meter wingspan, human face, saw teeth, snake body — and a cry read as the reproach of the unburied dead, asking how long they'd be left.
- Weaknesses
- The archer Hiroari's special arrow brought it down — a beat-for-beat echo of the nue's fall, one dynasty later.
- Oddities
- The Taiheiki calls it only "a demon bird" — the name is Sekien's coinage from the cry: the monster is medieval, its name an Edo editorial decision.

Overview
Over the imperial palace, in the plague year of 1334, a bird circled nightly, crying a human phrase: "itsumade, itsumade" — "until when? until when?" Human face, curved beak, saw teeth, a snake body, a wingspan near five meters. The archer Oki Jirōzaemon Hiroari brought it down with a special arrow — a beat-for-beat echo of Yorimasa and the nue, one dynasty of palace-bird crises later [wikipedia-itsumade], per Taiheiki.
The cry
The later (Shōwa-onward) reading gives the bird its meaning: the cry is the reproach of the unburied dead — plague and battlefield corpses left to rot, asking until when they'd be left [wikipedia-itsumade]. The interpretation is modern, and labeled as such — but it fits the Taiheiki's own context (the bird appears during an epidemic, over the court responsible), and it makes this one of the tradition's most quietly devastating figures. A monster whose whole body is a question the living won't answer.
Attestations
Taiheiki (14th c.); Sekien's plate (1779) fixed the name's kanji and the image [sekien-1779]; [wikipedia-itsumade]. The naming deserves its own note: the Taiheiki "merely calls it a 'demon bird'" — the name itsumade is Sekien's coinage from the cry; his plate "established the creature as a distinct yokai entity" [ja-itsumade]. The monster is medieval; its name is an Edo editorial decision — accretion of the benign kind: naming as curation. A variant modern reading makes the bird the war-dead themselves, transformed into avian form [ja-itsumade]. Its corpse-rite twin is the onmoraki.
