In the Edo period, advances in woodblock printing techniques led to the production of many printed materials and to the circulation of various yokai books among commoners. One of them was Picture Book of a Hundred Ghost Stories. This yokai book, consisting of five volumes, is a visual encyclopedia that introduces yokai comprehensively with pictures and text. It is also known as Night Tales of the Tōsanjin, named after its author Tōsanjin. Unlike previous yokai books, this book contains illustrations printed in color for the first time. The pictures of yokai are accompanied by their names and supplementary explanations, and the book also contains pages with detailed commentary.
"Hundred Ghost Stories" refers to the Edo-period popular recreation of telling ghost stories. The book mentions a total of 45 yokai, many of which were illustrated for the first time.

Yamachichi

Yamachichi is a yokai that hides in the mountains and sneaks up on people who are asleep to inhale their breath. It is said that a person whose breath was inhaled by Yamachichi will die the next day. However, if Yamachichi is seen doing this, the victim’s life will be spared and he/she will live a long life.

Mamedanuki

Mamedanuki is a clever raccoon dog yokai with a huge scrotum. Appearing in drizzling nights, Mamedanuki deceives people in search of food, blowing on his scrotum to stretch it out onto the ground and make it look like an eight-tatami-mat room, or putting the scrotum over himself to disguise himself as a deformed figure.

Futakuchi-onna

Futakuchi-onna is a female yokai who has a mouth in the front and back of her head. One day, a mouth formed on the back of this woman's head who did not give affection to the child of her husband’s ex-wife and starved the child to death. Her hair moved like a snake to feed the mouth on the back of her head, preventing the woman from eating and causing her to suffer.
