絵本百物語（えほんひゃくものがたり）
Ehon Hyaku Monogatari
The illustrated hundred tales of 1841, which gave its yokai a place and a story each.
Published in 1841 in five volumes, with text by a writer signing himself Tōsanjin and pictures by Takehara Shunsen, the book takes the form of a hyakumonogatari session and gives each creature a page, a picture and a short account set in a named province. The isonade, the shark whose tail drags sailors off the deck, is placed in the waters of Matsuura; the futakuchi-onna, the woman with a second mouth at the back of her head, is explained as the fate of a stepmother who starved a child.
Some of its yokai are older, some were reshaped, and some seem to have been written for the book. It is late in the Edo period and shows the genre at its most literary, with the pictures doing the frightening.

磯撫で（いそなで）
In the 1841 Ehon Hyaku Monogatari a shark-like creature of the western sea attacks with its tail — and in Kumano in 1960 the name was still the thing people said when someone died at the shore.
Futakuchi-onna
二口女（ふたくちおんな）
The 1841 Ehon Hyaku Monogatari made Futakuchi-onna a stepmother punished with a mouth at the back of her head. Folktales of the wife who eats nothing, recorded in the twentieth century, give the same hidden mouth to brides who turn out to be snakes, spiders, and oni.
