Yokai of Folklore
Yokai is a broad word for strange beings and uncanny events in Japanese folk belief. A river creature may have a dozen names from one valley to the next. A sudden cut on the skin, a knocking in the night or a household spirit might all be explained by a yokai. The word covers more than monsters: it is a way a community talks about what it cannot easily explain.
Many of the images we recognize come from illustrated books and prints of the Edo period (1603 to 1868), when artists collected and sometimes invented forms for older beliefs. In each scroll we try to separate the regional tradition from the picture that later made it famous.
How to read this shelf
- Look for the section on the earliest record: it often shows that the "classic" form is newer than the belief.
- Regional names are not errors. They are the tradition.
- A creature in a picture book is not always a creature in a village. We say which is which.
The 9 scrolls
What Is a Kappa? River Lore, Edo Prints and the Oldest Records
The kappa is a water being of Japanese folk belief, known by many regional names. It is recorded in dictionaries, Edo encyclopedias and prints, and in collectors' books from 1894 and 1910, and some shrines honor it as a water kami.
Who Is the Tengu? From a Barking Star to the Mountain Ascetic
The tengu is a winged, long-nosed mountain being tied to ascetics called yamabushi. Its name first appears in a court chronicle about a thundering star, and later tales, prints and temple traditions shaped the figure, which some temples still honor.
What Is a Kitsune? Shrine Messenger, Fox Wife and Possession Belief
The kitsune is the fox of Japanese folklore, a shape-shifting wife and a possessing spirit in tales that came from China, and also the messenger of Inari at shrines. These are separate traditions, known from tales, shrine pages and records of belief.
What Is a Tanuki? The Real Animal, the Shape-Shifter and the Statue
The tanuki is a real wild canid of Japan, a shape-changer in old and regional tales, and the glazed good-luck figure at shop doors. The sources differ on its earliest record, and the figure dates only to the early 1950s.
What Is a Bakeneko? Old Cats, Split Tails and the Nabeshima Tale
The bakeneko is the household cat that, in Japanese folk belief and Edo ghost stories, changes after long years and takes human form. Sources blur it with the nekomata, and its best-known tale, from Saga, was staged only in the nineteenth century.
What Is the Baku? Tracing the Dream-Eater from Chinese Screens to Pillows
The baku is a composite beast from Chinese texts that Japanese folk belief turned into a swallower of nightmares. Its record runs from a ninth-century Chinese preface through Edo-period carvings and pillows to Hearn's account of the call made after a bad dream.
What Is the Kamaitachi? The Unseen Cut in Edo Books and Snow Country
The kamaitachi is the unseen cause blamed in Japanese regional folk belief for a clean cut that appears without a blow. Its record runs from a 1666 tale collection and Sekien's 1776 picture to Edo-period notes and a 1929 physicist's essay.
Who Are the Namahage? The Masked Visitors of Oga and the UNESCO Listing
The Namahage are masked young men who visit houses on the Oga Peninsula in Akita at New Year, regarded in local belief as visiting deities. Records begin with an 1811 travel journal; UNESCO lists the custom only within a group of ten rituals.
What Is the Zashiki-warashi? The House Child of Tono and Its First Tales
The Zashiki-warashi is a child-like house spirit of Iwate and the Tohoku region, said to bring prosperity while it stays and decline when it leaves. The earliest record we read is Yanagita Kunio's 1910 Tono Monogatari, tales 17 and 18.
