Kayanohime no Kami is a kami of grasses and fields in Japanese mythology, whose name is associated with kaya, a term for thatch-grasses and reeds used in traditional construction and agrarian life. She appears in the Kojiki and Nihon Shoki among the deities born to Izanagi and Izanami, reflecting the早期 Shinto reverence for natural elements tied to the land and its cultivation. Shrines and local traditions honoring her often connect her to fertility of fields and the broader agricultural cycle, though specific ritual practices vary by region.
