Prince Yamato Takeru(ヤマトタケルノミコト,Yamato Takeru no Mikoto), originally Prince Ōsu(小碓命,Ōsu no Mikoto), was a Japanese legendary prince of the Yamato dynasty, son of Emperor Keiko, who is traditionally counted as the 12th Emperor of Japan.
The story of his life and death are told principally in the Japanese chronicles Kojiki (712) and Nihon Shoki (720), but also mentioned in Kogo shūi (807) and some histories like the Hitachi no Kuni Fudoki(常陸国風土記) (721). One of his sons became Emperor Chūai, the 14th Emperor of Japan.
