Yōkai (妖怪, Yōkai meaning"fishy", "mysterious", or "implausible") are a class of obake, creatures in Japanese folklore ranging from the evil oni to the mischievous kitsune or snow woman Yuki-onna. Some possess part animal and part human features (e.g. Kappa and Tengu). Yōkai generally have a sort of spiritual or supernatural power, and so encounters with human beings tend to be dangerous. Yōkai also have different motives and agendas from human beings, which are often completely incomprehensible.
