Nekomata

The name breaks into two parts: neko (猫, cat) and mata (又, forked or split). The compound describes exactly what the creature is. A domestic cat that has lived long enough, some sources say ten years, others thirteen, others simply “old,” undergoes a transformation. Its tail splits into two. With that physical change comes a set of powers no ordinary animal possesses: necromancy, shapeshifting, speech, and the ability to conjure fire from nowhere.

The earliest known written reference appears in the Meigetsuki (明月記), the diary of the court poet Fujiwara no Teika, under an entry from 1233. Teika recorded reports of a nekomata in the mountains of Nara province that had killed and eaten several people. He treated the account as current news, not legend. The creature was, to the educated Kyoto aristocracy of the thirteenth century, a real and present danger.

Appearance

The nekomata’s defining feature is its forked tail. Where an ordinary cat has one tail, the nekomata’s has split into two distinct branches, each moving independently. Beyond the tail, accounts vary. Some describe a cat of enormous size, large enough to overpower a grown man. The Tsurezuregusa of Yoshida Kenkō, written around 1330, mentions nekomata in the deep mountains as creatures “with eyes like cats but bodies as large as dogs.” Others keep the animal at domestic-cat scale, distinguishable from an ordinary cat only by the tail and by what happens around it.

Toriyama Sekien’s illustration in the Gazu Hyakki Yagyō (1776) depicts the nekomata as a cat standing upright on its hind legs, dancing beside ghostly flames. The image became the standard visual reference for the creature. The upright posture, a cat mimicking human stance, is a consistent detail across sources. The nekomata does more than gain powers. It imitates humanity.

Ghostly fire, called kitsunebi or kaika depending on the source, accompanies the nekomata. Blue or pale flames appear around the creature without burning anything nearby. In some accounts, these fires are only atmospheric. In others, they set real buildings ablaze. The ambiguity was part of the threat: you could not tell, looking at the flames, whether your house was about to burn.

Function

The nekomata serves two roles in Japanese folklore, and they operate on different scales.

At the household level, the nekomata is a domestic betrayal. A family raises a cat, feeds it, gives it a place by the hearth. The cat grows old. One day, the old cat begins behaving strangely. It walks on its hind legs when it thinks no one is watching. It speaks. It manipulates objects with its paws as though they were hands. Household items go missing. The elderly grandmother begins acting erratically, and the family suspects the cat is controlling her, or has replaced her entirely. This is the nekomata as household menace: the familiar turned alien, the pet revealed as predator.

At a larger scale, the nekomata is a mountain monster. The Meigetsuki account from 1233 places the creature in remote mountains, killing travelers. The Tsurezuregusa echoes this, describing mountain-dwelling nekomata as beings that “bewitch humans and eat them.” In this version, the nekomata has left domesticity entirely and become a wilderness predator, closer to a wolf or bear in function but with supernatural abilities no ordinary animal possesses.

Necromancy is the most disturbing power attributed to the nekomata. The creature can reanimate corpses by leaping over them or by dancing near them. In some Edo-period accounts, a nekomata at a funeral can cause the corpse to sit up and move. This is why, in traditional Japanese funerary practice, cats were kept away from the dead. The prohibition was practical, not symbolic. People believed the mechanism was real.

The shapeshifting ability follows a specific pattern. The nekomata does not become arbitrary things. It becomes people, usually women, usually someone the victim knows. A man returns home to find his wife behaving oddly, only to discover that his actual wife is locked in a closet and the figure at the table is the household cat wearing her form. The horror is domestic, intimate, and centered on the question of whether the person beside you is who they appear to be.

Cross-Cultural Connections

The nekomata exists on a spectrum with the bakeneko (化け猫, “changed cat”), and the boundary between them shifts depending on the source. In the loosest usage, a bakeneko is any cat that has developed supernatural abilities, and a nekomata is the specific subcategory with the split tail. In stricter usage, the bakeneko is a younger, less powerful stage: a cat that licks lamp oil, dances on hind legs, or speaks, but has not yet achieved the full nekomata transformation. The split tail marks the graduation from nuisance to genuine danger.

The structural parallel with the kitsune (fox) is hard to miss. Both are ordinary animals that gain supernatural powers with age. Both shapeshift, preferring female human forms. Both have a visible marker of their supernatural status: the kitsune grows additional tails (up to nine), while the nekomata’s single tail splits into two. Both can possess humans. Both operate in that space between the domestic and the wild, the trusted and the threatening. The fox has the longer literary pedigree in Japan and across East Asia. The cat arrived later, possibly influenced by the fox template.

Japan’s relationship with cats in folklore is consistent with a broader Eurasian pattern. The same animal worshipped in Egypt and feared in medieval Europe occupies a similarly ambiguous position in Japan. The nekomata is the Japanese answer to the European witch’s familiar, the cat that serves dark powers, and to the Egyptian reversal, the cat as sacred guardian. In Japan, the cat is both pet and potential demon, depending entirely on how long it lives.

Chinese sources contain references to supernatural cats with similar attributes, and the transmission route is likely. Buddhism carried texts and folklore from China to Japan for centuries before the first nekomata reference appears in 1233. The Chinese māo guǐ (cat ghost) tradition predates the Japanese nekomata, though the specific detail of the split tail appears to be Japanese.

Modern Survival

The nekomata did not fade. It adapted. Edo-period (1603-1868) kabuki theater featured nekomata stories regularly, with the cat-demon as a standard villain. The kaibyo (怪猫, “ghost cat”) film genre in twentieth-century Japanese cinema produced dozens of movies featuring nekomata and bakeneko, typically as vengeful spirits of cats mistreated by their owners.

In contemporary Japan, the nekomata appears across manga, anime, and video games with a frequency that suggests genuine cultural endurance rather than nostalgic revival. The creature shows up in Naruto, Pokémon (the design lineage from Espurr to Meowstic draws on nekomata imagery), Nioh, and Final Fantasy XIV. The forked tail has become visual shorthand: Japanese audiences recognize a two-tailed cat as supernatural without needing the backstory explained.

The old folk practice of cutting a cat’s tail short to prevent it from splitting has a direct modern echo. The Japanese Bobtail, one of the country’s most recognized cat breeds, has a naturally short, stumpy tail. Whether the breed’s popularity connects to centuries of nekomata anxiety is speculative. But the coincidence is noted in Japanese cat folklore scholarship, and it is a more interesting coincidence than most.
