Ugayafukiaezu-no-mikoto is a deity of Japanese mythology recorded in the Kojiki and Nihon Shoki, born on the shore where his mother Toyotama-hime was giving birth in a hut roofed with cormorant feathers not yet finished—an event reflected in his name. He is regarded as the father of Kamu-yamato-iware-biko, who became Emperor Jimmu, linking him directly to the mythic origins of the Japanese imperial line. Because of the unusual circumstances of his own birth, shrines associated with him are sometimes connected in local tradition to prayers concerning childbirth, though this association rests on popular veneration rather than canonical doctrine.
