Translation: light rain monk
Habitat: mountain roads
Diet: as a human (likely follows a monk’s diet)
Appearance: Kosamebō are yōkai which look like Buddhist monks. They loiter about on empty mountain roads at night. As their name implies, they only appear during nights when light rain is falling.
Interactions: Kosamebō accost travelers and beg for alms such as spare change or bits of millet to eat. Though frightening—and perhaps a bit annoying—they do not pose any real danger to humans.
Origin: Kosamebō appears in Toriyama Sekien’s yokai encyclopedia Konjaku hyakki shūi. Sekien describes them as appearing on the roads going through Mount Omine and Mount Katsuragi, two holy mountains in Nara Prefecture which have popular pilgrimage trails. They are also part of the local folklore of the Tsugaru region of Aomori Prefecture.
