Gazu Hyakki Yagyō (画図百鬼夜行, "The Illustrated Night Parade of a Hundred Demons") is the first book of Japanese artist Toriyama Sekien's famous Gazu Hyakki Yagyō e-hon series, published 1776. These books are supernatural bestiaries, collections of ghosts, spirits, spooks and monsters, many of which Toriyama based on literature, folklore, other artwork. These works have had a profound influence on subsequent yōkai imagery in Japan. (Also see: Hyakki Yagyō). The various creatures are described, below, using images to illustrate many of them.
