Hitotsume-kozo (一つ目小僧, "one-eyed boys") are cyclops creatures found in Japanese folklore.


Hitotsume-kozo are roughly the size of ten-year-old children, but otherwise resemble bald Buddhist priests. Their most distinctive feature, however, is a single, giant eye peering from the center of the face, along with a long tongue, much like a Tsukomogami monster.


Hitotsume-kozo are relatively benign creatures, content to run about frightening human beings or telling loud people to be quiet (they enjoy silence). However, many people consider an encounter with a one-eyed goblin to be a bad omen. For this reason, the superstitious often leave bamboo baskets in front of their houses, as these are reputed to repel the creatures. A reason for this may be that, in seeing the basket's many holes, the hitotsume-kozo will see the basket as having many eyes, and run away jealous and ashamed at only having one.

In reality, apart from a few tricks, they are almost never known to intentionally cause harm to anyone and may even bring good fortune.
