Kamaitachi
Image associated with the exact linked encyclopedia article; consult credited file description for its interpretation.
Overview
Kamaitachi associates sudden cuts or injuries with a passing wind and, in many representations, with a weasel-like supernatural attacker. The combination joins an unexplained bodily experience to a movement that can be felt but not easily grasped. Sekien's printed image provides a historical visual witness, while regional stories and later pictures vary in how they explain the injury and what sort of being caused it.
A familiar later version has several creatures act in sequence, but that arrangement should not be treated as the content of every earlier account. The name, artwork and local report can preserve different layers of the tradition. This entry focuses on the relation between wind, sharpness and an elusive agent. It makes no medical claim about actual wounds and no assertion that a distinct supernatural species explains the experiences recorded by storytellers.
Origins & earliest records
Selected illustrated witness: Toriyama Sekien's Gazu Hyakki Yagyō (1776). This is an attestation of the named representation, not a claim that the belief began in that year.
Records & interpretation
Historical prints and textual references establish an imagined being and its representation. The linked contextual article distinguishes the pictured form from regional accounts; these sources do not establish zoological existence.

Gazu Hyakki Yagyō
Selected historical witness; individual illustration now checked in the separately linked primary scan. This edition is not a claim of the earliest oral attestation.
Family, evolution & connections
Weasels
Kamaitachi representations join a weasel-like attacker with passing wind and unexplained cuts. The comparison with real weasels clarifies an animal-shaped visual motif without identifying the creature as a particular Mustela species. It also leaves regional explanations of the injury separate from Sekien’s surviving printed depiction.

Read the open encyclopedia overview
Kamaitachi (鎌鼬; Japanese pronunciation: [ka.ma.iꜜ.ta.tɕi]) is a Japanese yōkai from the oral tradition of the Kōshin'etsu region. It can also refer to the strange events that this creature causes.
They appear riding on dust devils and cut people using their sickle-like front claws, delivering sharp, painless wounds. The name is a combination of the words kama (sickle), and itachi (weasel).
