Panel from "Pictures of One Hundred Demons" by Kawanabe Kyōsai (1831–1889), aka “The Demon of Painting”. Hyakki Yagyō (The Night Parade of One Hundred Demons) is a 1000-plus-year-old Japanese folkloric tradition, in which a series of demons parades — or explodes — into the ordinary human world. Kyōsai’s contribution to the tradition was, according to the Metropolitan Museum of Art website, one of the artist’s most popular volumes, offering “a spectacular visual encyclopedia of supernatural creatures of premodern Japanese folklore”.
