The word, plainly
What it actually means
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.
Sekien's plate from 1779 carries its own definition, which is unusual — most of his pictures make you guess. This one tells you:
Jami is a kind of chimi — surely the evil vapour of wicked spirits.
That's not a creature with a biography. It's a classification, and the picture exists so that the category has a face.
The filing system
Japanese has an old compound word, chimimōryō, for the whole population of things out in the wild that mean you harm. It divides:
Chimi — the mountain-and-forest half. Miasma, mountain vapour, the malign atmosphere of high wild country.
Mōryō — the water half.
Between them they cover the unlabelled dread of anywhere outside the village, and the jami is the named specimen on the chimi shelf.
It's an import — Chinese demonology, where the type appears in the old immortal-biographies as something that possesses people until a healer traps it.
Why a category needs a picture
This is worth sitting with for a moment, because the tradition does it more than once.
Ayakashi is the sea's version — a general word for whatever the ocean does that it shouldn't. Majimun does the same work in Okinawa. Chimimōryō covers the wild.
Each of those words is a map of where a culture filed its unknowns, and each one eventually gets drawn — because a catalog needs an image, and a category has no body.
So Sekien draws a definition. Vapour with intent. The picture isn't a report of anything; it's a label with an illustration, and the honest reading is that the category came first and the shape was supplied afterward to fill the frame.
The gloss worth keeping
There's a later reading — Mizuki's — that the jami possesses only those bearing grudges.
It's a modern layer, and labelled as one. But it reads the import correctly. Miasma needs an opening. And in this tradition, the standing opening is resentment — the unresolved grievance that leaves a person permeable.
Which is the wrath-doctrine restated as epidemiology: the bad air is everywhere, and what determines whether it gets into you is what you're already carrying.
And a retraction, which is rare enough to note
Mizuki also gave the jami a design that breathed poison in GeGeGe no Kitarō.
And he later said it was a mistake.
That deserves a line, because this collection spends a great deal of its time untangling accretions that nobody ever owned up to — invented citations, fake regional pedigrees, details that arrived in 1972 and now read as ancient.
Here the man who did more than anyone to shape the modern canon went back and corrected his own contribution to it.
That's the behaviour every honest label in a project like this exists to encourage, and it's worth saying so when it happens.
Field guide
At a glance
- Behavior
- Not a creature but a classification with a face: the mountain-miasma class at its malevolent end — "surely the evil vapor of wicked spirits," per Sekien's own caption.
- Powers
- Possession — in the Mizuki-layer gloss, of "only those bearing grudges": miasma needs an opening, and resentment is the door.
- Weaknesses
- In the Chinese source, an immortal healer traps the type.
- Oddities
- With the water-realm mōryō, completes the idiom chimimōryō — the wild's unlabeled dread, filed.
- Mizuki later called his own poison-breathing design a mistake — the rare accretion layer with the author's retraction on record.
Overview
Sekien's plate carries its own definition: "Jami is a kind of chimi — surely the evil vapor of wicked spirits" [sekien-1779]; [ja-jami]. Not a creature with a biography but a classification: the mountain-miasma class (chimi) at its malevolent end, imported from Chinese demonology — the Shenxian Zhuan records the type possessing people until an immortal healer traps it [ja-jami].
The record
- The taxonomy: with mōryō (water-realm), the chimi (mountain-realm) complete the idiom chimimōryō — and the jami is the chimi shelf's named specimen in the catalogs [ja-jami].
- The Mizuki correction (on the record): Mizuki glossed it as possessing "only those bearing grudges"; his GeGeGe poison-breathing design he later called a mistake [ja-jami] — the rare accretion-layer with an author's own retraction: the audit shelf's most honest entry.
The reading
The tradition's pure category entries (ayakashi for the sea, majimun for the south, chimimōryō for the wild) each mark where a culture filed its unlabeled dread — the jami is that filing at its most explicit: Sekien drawing a definition, the picture existing so the taxonomy has a face. The grudge-only possession gloss (even as Mizuki-layer) reads the import correctly: miasma needs an opening, and resentment is the door — the wrath-system's doctrine restated as epidemiology. And the retraction deserves a one-line tribute: the reviver correcting his own canon is the behavior every honest label in this bestiary exists to encourage.
