Mōryō is a collective term for malevolent beings that dwell in mountains, rivers, plants, stones, and graveyards, often linked to water-born spirits. In Chinese classics it appears as wangliang or wuxiang, sometimes described as childlike figures with red-black skin, red eyes, and long ears. In Japan it was read as the water deity “mizuha” and later paired with chīmi (chimi) as a set. Mōryō are said to crave the livers of the dead and are associated with funerary disturbances and corpse-snatching apparitions.
