 Gazu Hyakki Yagyō

The book is a supernatural bestiary, a collection of ghosts, spirits, spooks and monsters from literature, folklore, and other artwork.The art of "Gazu Hyakki Yagyō" heavily references a 1737 scroll-painting called the "Hyakkai Zukan" by artist Sawaki Sūshi; Sekien's innovation was preparing the illustrations as woodblock prints that could be mass-produced in a bound book format.
