The Moving Anatomy Model (動く人体模型): The School Ghost Story

What is the moving anatomy model?

In the spring of 2024 the first-graders of a school in Fukui spent their first weeks exploring the building. Back in the classroom they had a “talking time”, and what they talked about was the science room: the skeleton and the anatomy model they had found there. Within a few sentences the talk had become a ghost story. At night, the children said, the models move. Dark empty rooms became haunted houses, and a rule appeared: get through in ten seconds or the ghost comes out.

A teacher wrote this down that August in a report on how children learn, and it is the freshest record of one of the oldest school ghost stories in Japan. The report is about storytelling, not about a model that moved. What it shows is how fast the story is made: a strange object, a dark room, a group of children, and no adult to say otherwise.

What does the name mean?

人体模型, jintai mokei, is a human-body model: the torso on a stand, with removable organs in painted plastic and half the face cut away to show the muscles, that stands in the science room of nearly every Japanese school. Ugoku means “it moves”. Its companion in the stories is the 骨格標本, kokkaku hyōhon, the skeleton specimen. The two are the only human-shaped things in a school building after the people have left, which is the whole of their qualification.

The science room after dark

The science room was already the haunted room of the school when folklorists began collecting from pupils. In 1985 and 1986 a teacher in Tokyo wrote down what his junior-high pupils told him. In one story a girl had thrown herself from the fourth-floor music room of a private school, a quarter of her face had been preserved as a specimen in the science room, and ever since, the room that was locked at dusk was found open in the morning. In another, a skeleton appeared in the dormitory mirror at two in the morning. In Yokohama in 1990 a pupil reported that the painting of a waterfall in the science room flowed at night.

The model and the skeleton belong to the same room and the same hour. The standard form, as the school ghost story collections give it, is that at midnight the skeleton, the anatomy model and the stuffed animals get up and wander the building. A version from Hiroshima has the two of them dance in the science room, and anyone who watches is pulled into the model’s stomach. The oldest memory attached to the story goes back to about 1948, at an elementary school in Kurosawajiri in Iwate: when the piano in the music room played, the skeleton in the science room directly below it danced.

How the story spread

The school ghost story became a genre in 1990, when a folklorist who had taught in junior high published a children’s book of the tales he had collected. It ran to nineteen volumes over the next quarter century, and its stories were set in the rooms every reader knew: the science room, the art room, the gymnasium, the stairs, the toilets. A film followed in 1995. In it the model in the old school building’s science room turns its plastic organs into real ones and walks, and it was popular enough to return in the third film two years later.

The 2024 report from Fukui shows the other way the story travels, which needs no book: six-year-olds who had never read it arrived at it in an afternoon.

Appearance

A life-sized torso on a stand, armless and legless, with the chest open and the organs showing in painted colour, and a face that is half skin and half muscle. In the stories it looks exactly as it does by day; the horror is that it is somewhere else. Our illustration keeps the model as a plain teaching object, pale plastic with a seam down the face, in a dark science room with the windows behind it.

Behavior and abilities

• It moves at night. It gets down from its stand once the school is empty.
• It walks the corridors. With the skeleton, and in some versions the stuffed animals too.
• It dances. When the music-room piano plays, in the Iwate memory; at midnight with the skeleton, in the Hiroshima version.
• It leaves traces. A locked science room found open in the morning.

Weaknesses and countermeasures

None are recorded, and the stories need none, because the model is never caught. Every version ends with morning and the torso back on its stand. The only countermeasure the children of Fukui came up with was speed: through the dark room in ten seconds, before the ghost comes out.

Documented rumour and later imagery

Documented rumour. Science-room ghost stories collected from Tokyo junior-high pupils in 1985 and 1986 and from a Yokohama pupil in 1990; the standard form of the skeleton, model and stuffed animals walking at midnight in the school ghost story collections from 1990; a memory from about 1948 in Kurosawajiri, Iwate, of the skeleton dancing under the music room; and a 2024 report from a school in Fukui of first-graders turning the science-room model into the story again.

Later imagery. The 1995 film gave the model real organs and a monster’s role, and the 2025 television series about a ghost-fighting teacher put the school’s midnight visitors into its third episode. On screen the model has to do something. In the stories children tell each other it does almost nothing: it is simply not where it was, and the room is open, and nobody saw.
