Bakeneko

In Japan, it was believed that very old cats gained supernatural powers: they could walk on their hind legs, speak, and even change shape, taking on the appearance of their own owner. Some legends went even further, telling of cats that replaced their dead owners and lived disguised in the house, with the family never noticing. When they grow a second tail, these cats become even more powerful and dangerous.

A cat that, on aging or reaching a certain size, gains supernatural powers: it walks on its hind legs, speaks, shape-shifts (even taking on its owner's appearance), and manipulates the dead. When it grows a forked tail, it becomes the more powerful nekomata.

Within the folk and mythological corpus compiled by the Codex Monstrorum, the creature Bakeneko occupies a distinctive role in the symbolic imagination of its culture of origin. Its mythos articulates primal human anxieties, the mystery of untamed wilderness, and social norms preserved through the lens of bestiary literature.

The belief links to the Japanese idea that very old animals acquire power. The bakeneko could bring fortune or misfortune: legends associate it with fires (licking lamp oil), with replacing a dead owner, and with controlling corpses. Stories of 'vampire cats' that devour owners and impersonate them circulated in kabuki theater. Codex distinguishes the supernatural household cat, the forked-tailed nekomata, and the modern reception (the cat-yokai also became an affectionate figure).

According to tradition, long-tailed cats were more likely to become bakeneko (hence the preference for short-tailed cats); for this reason, in some regions, cats' tails were cut. The bakeneko can dance with a towel on its head, speak human languages, and take the form of people. Mistreating it attracts vengeance; respecting it, protection.

First appearance and primary records: A supernatural cat of Japanese folklore, documented in Edo-period sources (17th–19th c.), in tale collections, theater plays, and ukiyo-e prints, drawing on earlier beliefs about cats.

Oral transmissions and preserved manuscripts indicate that legends surrounding Bakeneko underwent substantive evolution over successive centuries. From archaic oral traditions to classical and medieval written records, each period reframed the creature according to its own ethical and cosmological paradigms.

The morphology begins with the ordinary cat and adds the supernatural: increased size, erect posture, the ability to change form. The long tail is the sign of risk; when it forks, it marks the passage to the nekomata, more powerful. In human form, revealing feline traits linger.

The bakeneko organizes the ambivalence of the relationship with the household cat: companion and enigma, affection and distrust. Its function is to give form to the mystery of the animal that lives among humans yet keeps its autonomy, rewarding good treatment and punishing cruelty.

Beside the kitsune and the tanuki, the bakeneko is the cat among Japanese shape-shifting animals; it is distinguished by its domestic closeness and its link to the dead. It resonates with the nekomata (its advanced form) and with supernatural cats of other cultures, from the European witch's cat to the kumiho.

From Kuniyoshi's ukiyo-e prints and kabuki theater (monster-cat plays) to literature and horror cinema, and onward to manga, anime, and the ubiquity of the supernatural cat in Japanese pop culture (from the nekomata to the two-tailed cat), the bakeneko is one of Japan's most widespread yokai.
