In Edo-period prints, a cat stands on its hind legs with a hand towel knotted over its head, dancing.[5] It is one of the most recognizable images in the yokai tradition, and it is not a joke about pets.
Across woodblock prints, folktales, temple legends, and Edo stage plays, the cat is the animal Japanese folklore moves most readily across the line between the domestic and the uncanny — watching, remembering, transforming, occasionally avenging. Its yokai are not simple monsters, and not omens either. They carry human emotion (jealousy, grief, longing, resentment), household tension (family secrets, mistreatment, conflict left unspoken), and a question about where the natural stops and the supernatural begins.
Two figures dominate the tradition, and English-language books tend to call both of them simply cat demons: the bakeneko (化け猫), the cat that changes, and the nekomata (猫又), the cat whose tail has split in two.
Bakeneko means, literally, changing cat. It refers to an ordinary cat that has crossed an invisible threshold — usually through age, accumulated emotion, or spiritual saturation — and woken up with abilities it should not have.
Such a cat walks upright on its hind legs. It mimics human speech, sometimes the voices of the household it lives in; one Edo magistrate’s notebook records the opinion that any cat past its tenth year can talk.[3] It shape-shifts, often into family members. It handles fire, licking lamp oil or calling up ghostly flames. And it causes disturbances: mischief, illness, events no one can account for.
The transformation usually has an emotional history behind it. A cat mistreated by its household comes back for justice. A beloved pet lingers after death out of attachment. A quiet observer becomes a participant in the family’s drama.
So the bakeneko is less a straightforward threat than a mirror. The creature sharing the house has understood more than anyone realized, and what it exposes is the household’s own suppressed anxieties, resentments, and unspoken stories.
If the bakeneko is transformation, the nekomata is culmination: a cat so old, so steeped in memory and emotion, that its tail splits in two.
The forked tail is the visible mark. What comes with it is considerable — command over the dead, including reanimation; mastery of curses and spirit manipulation; an association with remote mountains. The nekomata is occasionally depicted as a large predatory animal rather than a house cat.
That ambiguity is historical. In the earliest records the nekomata is a mountain beast, enormous and dangerous: Fujiwara no Teika’s diary reports one killing people in 1233.[1] About a century later Tsurezuregusa repeats that there is a man-eating nekomata deep in the mountains, and adds that a house cat, grown old, may become one too.[2] By the Edo period the second version had won: an aged house cat accumulating spiritual power year by year until it passes beyond ordinary limits.
The idea underneath, as I read it, is a sharp one: the familiar can become fearsome when it survives long enough to witness too much.
| Bakeneko | Nekomata | |
|---|---|---|
| What it is | An ordinary cat that has crossed over | An elder cat at the end of that process |
| Mark | Walks upright, mimics voices, changes shape | A tail split in two |
| Powers | Shape-shifting, voice mimicry, fire, household disturbance | Command of the dead, curses, spirit manipulation |
| Setting | Inside the house | Mountains in early texts; the house by the Edo period |
The supernatural cat takes regional and artistic forms across Japan.
The towel-dance motif shows a bakeneko up on its hind legs with a hand towel over its head, and local legends attach it to real places — at Totsuka, on the Tōkaidō, the spot where the cats were said to gather and dance is still called Odoriba, the dancing ground. The dancing cat became the tradition’s emblem. (The dancing paper lantern often pictured beside it is a different creature altogether, the chōchin-obake.)
In kabuki and ukiyo-e, cat yokai frequently appear disguised as women — usually older women, with long sleeves concealing the tail. The disguise works because it combines elegance and mystery with hidden danger; the tail is the tell; and the dramatic unmasking became a kabuki staple.[4] The whole trope depends on the cat’s liminality, elegant and unsettling at once.
Utagawa Kuniyoshi (1798–1861) produced many of the best-known cat-yokai portraits in Japanese art. His cats have recognizably human expressions, two-tailed nekomata sitting upright with both dignity and menace, and domestic mischief rendered uncanny. His prints shaped how Japan pictures the supernatural cat, and they still do.[5]
Three currents explain why the cat, of all household animals, took on this role.
The first is liminality. Cats move between night and day, wildness and domestication, inside and outside, at their own discretion. Folklore only has to raise that to supernatural potential: the cat is already a boundary-crosser, and becoming a yokai is the next step.
The second is longevity. Edo folk belief held that old animals, especially long-tailed ones, develop magical abilities over time — enough that some households are said to have cut their cats’ tails as a precaution. That detail is the one I keep coming back to: a practical household measure taken against a metaphysical outcome. A cat that has watched a house for decades knows its secrets, and the cat’s relatively long life made it the obvious vessel for the logic.
The third is moral ambiguity. Cats were essential for pest control and kept close, yet never fully domesticated, never quite legible, watching without revealing anything. Folklore translated that into narrative ambivalence: sometimes a benevolent protector, sometimes a vengeful spirit, always watching and always remembering. The cat yokai is morally complex because the cat is.
Contemporary Japan has kept its cat yokai and made them affectionate. They appear in anime and manga — GeGeGe no Kitarō, Ayakashi: Samurai Horror Tales and its successor Mononoke — in horror anthologies and yokai films, in yokai-collection games and RPGs, in illustrated encyclopedias for children, and in regional mascots, folklore festivals, and local tourism.
The tone has inverted. Where the classical material offered genuine fear and moral warning, the modern version offers affection, nostalgia, and aesthetic appreciation. Cats that were potential threats are charming companions now, and transformation that was punishment is possibility.
The old intuition survives underneath. The cat beside you is never only a cat: it is a sentinel of secrets, an inheritor of the household’s emotional history, and, when the conditions converge, a vessel for something else.
Cat yokai endure because they are built from the qualities that make cats compelling in the first place, each of which has a shadow: beauty and danger, grace and unpredictability, intimacy and mystery, companionship and independence, familiarity and unknowability.
Between them, bakeneko and nekomata state a principle that runs through the whole tradition — the boundary between the ordinary and the uncanny is thinnest where the familiar lives. Pets are never merely pets. Observation accumulates into power. The domestic interior is where the supernatural is most at home.
Nowhere is that boundary thinner than in the sound of a cat crossing the house at night, eyes catching what light there is, knowing more than it will ever say.
