Toyotamahime-no-mikoto is a deity of Japanese mythology, daughter of the sea god Ryūjin, who appears in the Kojiki and Nihon Shoki as the wife of Hikohohodemi (Yamasachihiko). She is especially known for the story of her childbirth on land, during which she transformed into a dragon or sea creature, an episode that has led to her veneration in connection with pregnancy and safe delivery. She is enshrined at various shrines, including Kamo Shrine in Kagoshima, where devotees traditionally seek her favor for matters of fertility and childbirth.
