Hyakki Yagyō
Hyakki Yagyō (百鬼夜行; lit. "Night Parade of One Hundred Demons"[citation needed]) is a concept in Japanese folklore.
Towards a Working Definition of Hyakki Yagyō
Legend has it that "every year yōkai, the Japanese supernatural beings, will take to the streets during summer nights." Anyone who comes across the procession would die, "unless protected."[1] The children's game Hyakumonogatari Kaidankai was based on this idea.[1]
Hyakki Yagyō in Art
The night parade was a popular theme in Japanese visual art.[citation needed]
An early example is the famous 16-century handscroll Hyakki Yagyō Zu (百鬼夜行図),[citation needed] attributed to Tosa Mitsunobu,[citation needed] is located in the Shinju-an of Daitoku-ji, Kyoto.[citation needed]
Notable other works of this motif include those by Toriyama Sekien (Gazu Hyakki Yagyō)[citation needed] and Utagawa Yoshiiku.[citation needed] These works are more often considered "humorous than frightening."[citation needed]
In the Ghibli movie Pom Poko, "Operation Spectre/Operation Poltergeist was intended to evoke the Hyakki Yakō."[citation needed]
