Satake Masayoshi
Satake Masayoshi (1081–1147) was a late Heian warrior and the founder of the Satake clan of Hitachi Province. A grandson of Minamoto no Yoshimitsu and eldest son of Minamoto no Yoshinari, he settled at Satake and styled himself Satake Kaja.
In 1106 he helped repel his uncle Yoshikuni's invasion of Hitachi. He married a daughter of Fujiwara no Kiyohira, and their son Takayoshi succeeded him, laying the base of Satake power in northern Hitachi.
