Gazu Hyakki Yagyō is the first book of Japanese artist Toriyama Sekien's famous Gazu Hyakki Yagyō e-hon tetralogy, published in 1776. A version of the tetralogy translated and annotated in English was published in 2016. Although the title translates to "The Illustrated Night Parade of a Hundred Demons", it is based on an idiom, hyakki yagyō, that is akin to pandemonium in English and implies an uncountable horde. The book is followed by Konjaku Gazu Zoku Hyakki, Konjaku Hyakki Shūi, and Gazu Hyakki Tsurezure Bukuro.

Konjaku Gazu Zoku Hyakki is the second book of Japanese artist Toriyama Sekien's famous Gazu Hyakki Yagyō tetralogy, published c. 1779. A version of the tetralogy translated and annotated in English was published in 2016. 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. Konjaku Gazu Zoku Hyakki is preceded in the series by Gazu Hyakki Yagyō, and succeeded by Konjaku Hyakki Shūi and Gazu Hyakki Tsurezure Bukuro.
