A yokai said to appear at funerals, funeral processions, and graveyards to snatch coffins and corpses. In the early modern period it was told as a hellish jailer or thunder god’s doing, stealing bodies amid black clouds and lightning. Later it merged with bakeneko lore, spreading the belief that an aged cat becomes a kasha and preys on the dead. Reports occur nationwide and are not strictly framed as moral retribution. Traditional countermeasures include blades, prayer beads, mounded earth, and constant vigil.
