Yamato Takeru was a legendary prince of the Yamato court, celebrated in the Kojiki and Nihon Shoki as a warrior who subdued rebellious lands in eastern and western Japan. Ototachibanahime was his consort, remembered for the tradition that she cast herself into the sea to calm a storm and protect him during his campaign through the Sagami region, an act later regarded as a profound expression of devotion. Together they are often invoked in connection with love and marital loyalty, though such associations reflect later veneration and folklore rather than a fixed original role.
