Minamoto no Yoshimitsu

Minamoto no Yoshimitsu (1045–1127), known as Shinra Saburō, was a late-Heian warrior, the third son of Minamoto no Yoriyoshi and younger brother of Yoshiie. He served in the Later Three Years' War, after which he was made governor of Kai Province and settled there.

He later fought his nephew Yoshikuni over land, and after Yoshiie's death was suspected of plotting the murder of Yoshitada. His son Yoshikiyo took the name Takeda, making Yoshimitsu ancestor of the Takeda clan; tradition also credits him with founding Daitō-ryū jūjutsu.
