Nekomusume

Also Known As: 猫娘, “cat daughter”
Region/Culture: East Asia (Japan)
Mythos: Japanese Mythology
Primary Type/Nature: Shapeshifter / cat yokai, a variant of the bakeneko
Mythical Attributes: A girl or young woman carrying the features, appetites, and instincts of a cat, poised on the line between human child and feline spirit.
Role in Mythos: She surfaces as an uncanny household member or a sideshow curiosity whose cat nature gives itself away through her tastes and the way she moves.
Relation to Humans: She lives among people and is often taken at first for an ordinary girl, until someone sees her worrying at a fish head or going up a wall like something that does not need the stairs. Some tellings treat her as a harmless oddity to be gawked at; others as a quiet warning that a cat kept long enough in a house stops being only a cat.

The booth stood among the other attractions at Asakusa, a paper lantern throwing weak yellow light on a hanging cloth, and for a few coins you could go in and see the cat girl. She sat on a raised mat and did very little. Now and then she lifted the back of her hand to her mouth and worked at it with her tongue, the way a cat cleans itself, and the sound of that rough tongue was enough to make the front row lean back. When a fish was set down she took it in both hands and ate from the head. People came out saying they had seen a real one, an actual creature out of the old stories, and for a season in the late 1760s that was the most talked-about thing in the pleasure district.

Whether she was a spirit or a very committed performer was, in a sense, beside the point. The nekomusume lived in exactly that gap. Her name is plain enough, neko for cat and musume for daughter or girl, and the plainness is part of the unease: not a monster with a monster’s name, just a daughter who happens to be a cat, or a cat who has come far enough toward being a daughter that you would have to look twice. Edo delighted in that kind of thing. The city kept records of its human oddities and its sideshow marvels, and the cat girl turns up in them as a woman likened to a cat in her manners, her cravings, and her gait, exhibited here and there before her fame burned out. Kitamura Nobuyo, cataloguing the amusements of the age in the early nineteenth century, is among those who preserved her.

Underneath the sideshow sat something older and less comfortable. The nekomusume is usually filed as a kind of bakeneko, the shape-changing cat that Japan has always half-expected of any animal allowed to grow old in the warm part of the house. A cat that lives long enough, the belief ran, learns things it should not: to stand, to speak, to take the face of the dead, to dance when no one is watching. The cat girl is that transformation caught partway, or coming from the other direction. In some tellings she is a human child born into a family that already had a strange or beloved cat, and she grows up wrong, drawn to raw fish and mouse-runs and high places, licking her hands clean and hissing when startled. In others she is the cat itself, edging into a girl’s shape but never able to put the whole of the cat away.

The picture books of the period gave her stories. An illustrated collection of ghost tales from around the turn of the nineteenth century sets down a nekomusume among its wonders, and the shape of such a tale is easy to feel even where the details differ from telling to telling: a household notices that the daughter is not like other daughters, that food goes missing in a particular way, that the neighbourhood cats gather at the wall for her. The revelation, when it comes, is domestic rather than bloody. There is no great battle. There is a family looking at a child they thought they knew and understanding, too late, what had been sitting at their table.

What she can do follows from what she is. She has the cat’s advantages worn on a human frame: she climbs where people cannot, moves without sound, sees in the dark, and passes, for a while, as one of us. That passing is the real power, the ability to sit at the hearth or on the sideshow mat and be taken for a girl until she chooses, or forgets, to be otherwise. Against that stands the single thing she cannot manage, which is to keep the cat hidden. The instinct always surfaces. The fondness for fish, the rough tongue, the low pounce after something scuttling in the dark, the reflex to go up rather than around, these betray her every time, and the older stories treat that as a kind of justice: a nature cannot be worn as a costume forever. The sideshow version has a blunter limit still. A marvel that depends on a crowd’s belief lasts exactly as long as the fashion does, and the crowds moved on.

She did not stay gone. In the twentieth century the manga artist Mizuki Shigeru made a Nekomusume one of the regular companions of his long-running yokai comic, redrawing the cat girl as a sharp-eyed young heroine who turns fierce and feline when provoked. That version, entirely modern, is the one most people in Japan now picture first, and it has quietly rewritten the older figure in the popular mind. It is worth keeping the two apart. The bright cartoon ally and the unsettling thing on the Asakusa mat share a name and a pair of ears, and almost nothing else.

Frequently Asked Questions

What is a Nekomusume?

A Nekomusume is a cat-girl yokai of Japanese folklore, usually treated as a form of bakeneko, the shape-shifting cat. She appears as a young girl or woman who carries a cat’s features, appetites, and instincts, standing on the boundary between human and feline spirit.

Where does the Nekomusume come from?

The name and figure took hold in Edo-period Japan, where “cat girl” first referred to real sideshow performers and human oddities likened to cats, exhibited in Asakusa and elsewhere around the late 1760s. That popular attraction fused with the older bakeneko tradition of cats that transform after living too long in a human household.

What makes someone recognize a Nekomusume?

Her cat nature gives her away through her behaviour rather than obvious monstrousness. Accounts describe a fondness for raw fish and hunting mice, a rough cat-like tongue, sudden low pounces, and a habit of climbing walls and moving in silence, all surfacing in a girl who otherwise looks human.

Is the Nekomusume dangerous?

She is more uncanny than deadly in the traditional tales, closer to a household unease or a curiosity than a killer. The horror in her stories tends to be domestic, the slow realization that a child or member of the household was never entirely human.

Is the modern GeGeGe no Kitaro Nekomusume the same as the folklore one?

No, though they share a name. The manga artist Mizuki Shigeru reimagined the Nekomusume in the twentieth century as a recurring heroine, and that cartoon version is now the most familiar in Japan. The older folkloric cat girl of the Edo sideshows and ghost-tale picture books is a stranger, more ambiguous figure.
