Yamato Takeru (c. 72-113), originally known as Prince Osu, was a legendary and mythical figure in Japan. He was a prince of the Yamato Dynasty, son of 12th emperor of Japan, Emperor Keiko. The life and death of Yamato are primarily chronicled in the tales 'Kojiki' (712 CE) and 'Nihon Shoki' (720 CE).

For slaying his elder brother, Osu was sent to fight in Izumo Province by his father, who feared his brutal temperament. Instead of being killed however, Osu succeeded in defeating his enemies and was gifted the title 'Yamato Takeru' (The Brave of Yamato). His father was not convinced, still fearing him and wishing his death.

Next, Yamato was sent eastwards to deal with those who had disobeyed the imperial court, armed with the holy sword 'Kusanagi'. During a great storm, his wife sacrificed herself to appease the sea god, and in his anger he defeated many enemies. However, his blaspheming of a local god of Mount Ibuki led to him being cursed and dying. His soul turned into a great white bird and flew away. His tomb is located in Ise Province, and is known as the Mausoleum of the White Plover.
