An oni (鬼おに) is a kind of yōkai, demon, ogre, or troll in Japanese folklore. They are typically portrayed as hulking figures with one or more horns growing out of their heads. Stereotypically, they are conceived of as red, blue, or white-colored, wearing loincloths of tiger pelt, and carrying iron kanabō clubs. They are popular characters in Japanese art, literature, and theater,[1] and appear as stock villains in the well-known fairytales of Momotarō (Peach Boy), Issun-bōshi, and Kobutori Jīsan.
