A funeral procession in old Japan was never entirely safe. Between the moment a person died and the moment their body was sealed in the ground, mourners kept watch, because a corpse left unguarded could draw the attention of the kasha — the "fire cart" — a burning, cat-faced thing said to plunge from a black cloud, rip open the coffin, and haul the body off before the priests could finish their sutras.
What does it look like?
Accounts describe the kasha as a monstrous cat or cat-demon wreathed in flame, sometimes riding or dragging a burning wheeled cart, sometimes appearing as the cart itself, spokes alight, rattling down from the sky. Toriyama Sekien drew it in his Gazu Hyakki Yagyō (1776) as a cat-like creature wrapped in flames. Earlier pictures showed it more like a thunder god or hell demon. The name itself, written 火車, is borrowed from a Buddhist term for the burning cart that ferries sinners to hell, and folklore fused that idea directly onto a cat.
A funeral thief with a moral
Many tellings say the kasha came for the wicked. Edo stories often name a greedy or cruel person as its victim. Scholars note that folk accounts do not always follow this rule. Dark clouds, thunder and sudden storms were read as signs that a kasha was near. In some tellings it simply snatched the corpse and vanished; in others it left the body torn apart, a punishment made visible for everyone at the funeral to see.
This is one reason some regions kept a strict vigil. In parts of Miyazaki, someone stayed beside the body day and night. Without a watch, people said, the kasha would come. A kasha attack was less a random horror than a kind of folk justice — proof, to a village, that the dead man's debts had finally come due.
The old cat behind the fire
Most folklorists trace the kasha back to the nekomata, the forked-tailed cat that grows monstrous with age, and to a wider belief that a cat allowed to live too long, or one that leaps over a corpse, can reanimate the dead or steal it away. In Miyazaki and Gunma, people kept cats away from the dead. Some shut the cat in a basket during the wake. Over time the corpse-stealing cat and the Buddhist hell-cart merged into one figure: a monster that was both an animal grown sinister with age and an agent of otherworldly punishment.
How mourners fought back
Folklore gave funeral parties real countermeasures, not just fear:
- A blade on the coffin. In Ehime, a razor on the coffin was said to keep the kasha from taking the body. Parts of Gunma used blades the same way.
- Unbroken vigil. Mourners took shifts so the body was never left alone between death and burial — the single most consistent defense across regional accounts.
- Spells and prayer beads. Sekien wrote that each region had its own spell against it. In one Miyazaki village, mourners said "We won't feed it to the kasha" twice. Edo accounts tell of priests driving it off with prayer beads.
- A decoy funeral. Near one temple in Yamanashi, people held two funerals. The first coffin was filled with stones.
None of these were treated as guaranteed. A kasha that wanted a particular corpse badly enough, the stories imply, would eventually get it — the rituals bought time, not certainty.
Where it comes from
The kasha sits at the intersection of two much older ideas: the aging housecat as a source of supernatural danger, and the Buddhist image of hell's burning chariot arriving to collect the guilty. Japan's folk imagination rarely separated animal and punishment cleanly, and the kasha is one of the clearest results — a monster that is simultaneously a predator, a portent, and a verdict on how someone lived.

Kasha today
The kasha appears far less often in modern media than its cousin the bakeneko, but it survives in regional funeral customs and in scholarly retellings of Edo kaidan (ghost story) collections, and Sekien's original woodblock print is still reproduced in books on yokai art as one of the more unsettling entries in his bestiaries. A 1984 Ehime prefectural history still records the razor on the coffin, a habit whose original purpose — keeping a burning cat-demon from the dead — long outlived general belief in the creature itself.
