The Kaibutsu Ehon ("Illustrated Book of Monsters") is an 1881 book featuring woodblock prints of yōkai, or creatures from Japanese folklore. Illustrated by painter Nabeta Gyokuei, the book is modeled after the influential works of Toriyama Sekien, an 18th-century scholar and ukiyo-e artist known for his attempt to catalog the many species of yōkai in Japan. Here are 25 monsters from the book. Miko
