Toyotama-hime-no-mikoto is a deity in Japanese mythology, recorded in the Kojiki and Nihon Shoki as the daughter of the sea god Ryūjin. She married the hunter-prince Hikohohodemi (Yamasachi-hiko) and, according to the myth, gave birth to their child on land in the form of a dragon or sea creature, an episode central to her association with childbirth. Because of this narrative, shrines connected to her are often linked to safe delivery and fertility, though such benefits reflect traditional belief rather than verified fact.
