Hitotsume-kozō

Also Known As: 一つ目小僧; “one-eyed little monk”; also Mehitotsu-kozō, and called Yōkazō in parts of Kanagawa
Region/Culture: East Asia
Mythos: Japanese Mythology
Primary Type/Nature: Fairy Folk and Spirit Beings
Mythical Attributes: A hitotsume-kozō walks the villages on the calendar’s dangerous eighth nights, inspecting houses and writing down what it finds.
Role in Mythos: It is the inspector of the kotoyōka nights, the eighth of the twelfth month and the eighth of the second, when a household’s carelessness is entered in a ledger and paid for the following year.
Relation to Humans: It does not tear anyone apart, but it does keep records, and the accounts are settled in sickness. Households met it with baskets, holly, burnt onions and an early bolt on the door.

The lamps went out early on the eighth night of the twelfth month, all across the Kantō plain, and the geta came in off the step. Out in the yard a bamboo basket went up on the end of a long pole, tilted so that the lattice caught what light there was, every gap in the weave sitting in the dark like an open eye. Onions burned on the hearth. Somebody threw gumi wood on the fire because the smoke of it stinks, and the stink was the point. Then the shutters went across, and the family sat inside and listened to the lane.

What they were listening for was a child. That is the strange, small horror at the centre of this: not a horned giant, not a thing with teeth, but a boy in a novice’s robe with a shaved scalp, about the height of a nine-year-old, coming up the frozen lane at his own pace. His face carries one eye and nothing else worth mentioning, and in the Kanagawa tellings the eye is red. Some accounts give him a long tongue that he uses on people who get too close. He is not much of a monster. He is a clerk.

The work is precise. He goes from house to house in the dark, and any clog left outside gets a burn-mark pressed into it so the household can see, in the morning, that it was caught. A rain shutter forgotten, a door left unbarred, a lapse in the ordinary discipline of a farmhouse: it goes into the ledger. The punishment is not delivered on the night. It arrives across the following year, when someone in the marked house falls ill with a fever that spreads, and the family understands why. In an age when a village could lose its children to a single epidemic, this was not a ghost story so much as an explanation, and a warning to keep the place in order.

Against a creature with one eye, the countermeasure follows with a certain rural logic. He cannot bear to look at anything that has more eyes than he does. So the me-kago, the coarse winnowing basket whose weave is full of “eyes”, went up on a pole above the eaves, or was upended on the roof, or hung in the doorway with a sprig of holly pushed through it. In the villages of Kanagawa in the nineteen thirties, an old woman was still doing this every December with the big basket she used to carry fallen leaves, and her neighbours with the basket they washed potatoes in. He comes to the gate, sees a hundred eyes staring back, clutches his head and runs.

He is also, it turns out, easy to cheat. In the Ebina telling, the hitotsume-kozō finishes his rounds with the ledger full and stops at the crossroads on his way out of the village, where the Dōsojin, the stone guardian who sits at the boundary, is minding his own business. Year-end is busy. The kozō hands over the book, asks the god to hold it for him, promises to collect it on the fifteenth of January, and goes. On the night of the fourteenth the villagers pile the old pine decorations and the year’s spent talismans in front of that same stone and set them alight. When the kozō comes back for his ledger, the Dōsojin apologises: there was a terrible fire here last night, and your book, your important book, burned in it. The kozō looks at the heap of ash, accepts the loss, says he will see them next year, and trudges off. Everything is forgiven for another twelve months, by arson, with the god as accomplice.

He does not travel alone. In the same districts a one-eyed old woman comes on the same nights, the Mikaribaba, who is said to put her eye to a hole in the paper screens and to carry off children, and who is repelled by exactly the same baskets. The eighth days of the second and twelfth months were called kotoyōka, and they were understood as the hinge nights when something from the mountains crosses into the settled world and has to be turned back at the door.

Where he comes from is a harder question, and the most influential answer is a modern one. In August 1917 the folklorist Yanagita Kunio published an essay on the hitotsume-kozō in a Tokyo newspaper, and reprinted it in 1934 in a volume that took its name. His argument was that when old beliefs are pushed aside by new ones, the old gods do not simply vanish. They are demoted. Yōkai, in his phrase, are deities that have lost their sanction, and the one-eyed boy is what remains of a one-eyed mountain god. Yanagita pointed to the country’s one-eyed divinities, to the traditions of a god of the mountains who sees with a single eye, and to the darker hint that a human sacrifice was once marked out by the taking of an eye. It is a compelling reconstruction and it has shaped almost everything written about the creature since. It is also a theory from 1917, not the belief of the farmers who hung the basket, and the two should not be confused.

What he has, in the end, is knowledge. He sees what a household does when it thinks nobody is watching, and he writes it down, and the writing turns into fever. What he lacks is nerve and wit. He can be driven off by a potato basket, blinded by an idea of a hundred eyes, gagged by onion smoke, and swindled out of his own evidence by a lump of stone at a crossroads. His whole power depends on the ledger surviving until the fifteenth of January, and every year the village makes sure it does not.

Frequently Asked Questions

What is a hitotsume-kozō?

A hitotsume-kozō is a Japanese yōkai that looks like a small boy with a shaved head, a novice monk’s robe, and a single large eye in the middle of its face. It appears in folk custom rather than in epic myth, walking the villages on the eighth nights of the twelfth and second months to inspect houses and record their faults.

What does a hitotsume-kozō do to people?

It does not attack. It notes down each household’s carelessness, such as clogs left outside or shutters left open, in a ledger, and a house that is written up is expected to suffer an infectious illness during the coming year. In Kanagawa records it also brands the footwear it finds outside so the family knows it has been marked.

How do you keep a hitotsume-kozō away?

The standard protection is a coarse basket, a me-kago, hung in the doorway or raised on a pole above the roof, because the many “eyes” in its weave terrify a creature with only one. Villagers also burned onions and foul-smelling gumi wood, stuck holly through the basket, brought their footwear indoors and closed the shutters early.

What is kotoyōka?

Kotoyōka is the name for the eighth day of the twelfth month and the eighth day of the second month, the nights when the hitotsume-kozō and the one-eyed hag Mikaribaba were said to come down into the villages. It was treated as a dangerous hinge in the year, when people avoided travel, made offerings and put out the baskets.

Where does the hitotsume-kozō come from?

The best-known explanation is the folklorist Yanagita Kunio’s, set out in an essay of 1917 and reprinted in 1934, which treats the creature as a mountain god fallen out of worship, since yōkai in his reading are simply deities who have lost their official standing. Yanagita connected the single eye to one-eyed mountain deities and to old traditions of marking a sacrificial victim by taking an eye. This is a modern scholarly reconstruction rather than a story the villagers themselves told.
