A yokai appearing as a shaven-headed boy with a single large eye in the center of his forehead. More prankster than predator, it startles people by popping up suddenly and is often portrayed with humor. A folk pun led to the belief it dislikes beans, which later shifted into depictions of it favoring tofu. It appears in Edo-period picture scrolls and essays, and is often encountered outdoors or by the roadside.
Folklore & Legends
In the Edo tale Kaidan Oi no Tsue, a boy playing with a hanging scroll in a samurai residence turns around to reveal a single eye; residents say the harmless disturbance occurs a few times a year. In Aizu, one glared at a girl on the road, causing her to faint. In Bizen, it appeared on a night path glowing pale blue and licked a man who collapsed in fright, giving rise to a place-name story. In Tamba-Sasayama, a small one-eyed boy appears on a rainy late-autumn night at Bansho Bridge, said to unnerve even samurai.
A整理 based on Edo-period picture scrolls such as Hyakkai Zukan and Bakemono-zukushi depicting the figure known as Hitotsume-bō. It takes the form of a shaven-headed child monk, appearing suddenly in parlors, on bridges, slopes, and crossroads, then vanishing once satisfied with the onlooker’s reaction. Though often associated by inference with the one-eyed, one-legged monk of Mount Hiei, direct identification is avoided. Folklore links it to food by claiming it dislikes beans, and later images show it carrying tofu, yet it rarely intends harm to people or livestock. Its appearances vary by season and weather; in some regions, its single eye is said to glow dimly on rainy nights in late autumn. Names vary by locale, including “Hitotsu-managu” in Ōshū and the widespread “Hitotsume-kozō” and “Hitotsume-bō.”
