Ittan-momen (一反木綿): The Flying Bolt of Cotton

What is Ittan-momen?

On a night road in the Kōyama district of Kagoshima, at the southern end of Kyushu, something white appears in front of you. It is long and narrow and it is moving the way a strip of cloth moves in wind, except that there is no wind. It flutters at your face until you cannot see — and then it attacks.

That is the ittan-momen as it was recorded in 1956, and it adds one detail to the barest note of all, Yanagita Kunio’s of 1938: there is a monster called the ittan-momen; a thing in the shape of a bolt of cotton appears at night, flutters, and attacks people.

The image works because the object is so ordinary. A length of white cloth belongs in a house, a workshop, a market stall. On a dark road, moving under its own power, it is neither animal nor ghost — a piece of household goods behaving with intent.

What does ittan-momen mean?

The name is written 一反木綿. Ittan is one tan, the traditional measure of cloth: a bolt long enough to make one adult kimono, roughly ten metres by thirty-odd centimetres, though the exact figures varied by period and place. Momen is cotton. One bolt of cotton — the thing you would buy to have a robe made. The name is a shopping measure, and the creature is exactly that much fabric.

Appearance

A long strip of white cotton, and nothing else. Neither record gives it a face, eyes, a mouth, arms or legs. Our short keeps it that way: one faceless bolt of old white cloth, moving against the wind above a lantern-lit road between fields, with low stone walls and windbreak trees — the southern landscape the records belong to.

Its personality is in its flight. A turn into the wind, a sudden drop, a hesitation at the edge of the lantern light can make a strip of cloth look alert without giving it a face.

Behavior and abilities

• It appears at night, on a road, in front of you.
• It flutters. Both records use the word hira-hira, the sound of cloth in air.
• It dazzles. The 1956 record has it fill a person’s eyes with white before anything else happens.
• It attacks. Both records say so, and neither says how.

The strangling, the wrapping round the neck, the blood that runs when it is cut — those are in later retellings, and the two Kōyama records carry none of them.

Weaknesses and countermeasures

None in either record. No cutting, no burning, no charm. The accounts describe an appearance and an attack and stop there, which leaves the traveller on the Kōyama road with nothing but the lantern and the distance to the next house.

Documented tradition and later imagery

Documented tradition. A monster in the shape of a bolt of cotton that appears at night, flutters and attacks people (Yanagita Kunio, Yōkai Meii, Kimotsuki, Kagoshima, 1938); a white bolt-like thing that appears before a traveller on a night road, flutters, dazzles the eyes and attacks (Kōyama district, 1956).

Later imagery. Manga and television gave the cloth a pair of eyes and a mouth, a cheerful Kagoshima accent, and a job carrying heroes through the air; horror versions gave it the neck. The records have a strip of white in the dark and a word for the sound it makes.
