Youkai (written with kanji meaning "bewitching apparition") are traditional Japanese monsters of supernatural origin. The word is often translated as "goblin" or "demon". Youkai are grotesque, diverse, and often as silly as they are terrifying. They were a popular subject in
ukiyo-e prints, and the artist
Toriyama Sekien is famous for publishing an extensive, illustrated
bestiary of the creatures. Some of the best known
youkai include oni (large, horned ogre-like demons who punish sinners in hell),
tengu (beaked or long-nosed bird-men), kappa (turtle-like water-imps), and kitsune and tanuki (foxes and raccoon-dogs - real animals to whom supernatural powers were attributed).
