Satake clan
The Satake clan claimed descent from Satake Masayoshi, the grandson of the prominent 11th century warrior Minamoto no Yoshimitsu. Yoshimitsu received land in Mutsu Province and Hitachi Province as a reward for his military service, and took up residence at Satake village, in Hitachi. Yoshimitsu willed the territory around Satake village to his son, Yoshinobu. Yoshinobu, in turn, passed it on to his own son, Masayoshi. The Satake clan would remain in Hitachi until they were ordered to move in 1602. In 1106, Masayoshi led a rebellion against Minamoto no Yoshikuni, a power figure in neighboring Shimotsuke Province, but was defeated and killed by Yoshikuni, who followed him back to Hitachi. During the Genpei War, Masayoshi's son Takayoshi sided with Taira no Kiyomori. The Satake clan was defeated by Minamoto no Yoritomo in 1180, and its territory confiscated; it was not until nine years later that Yoritomo forgave Takayoshi's son Hideyoshi, and allowed Hideyoshi to become his vassal. Hideyoshi served in the attack on Mutsu Province. The Satake clan later returned to its old territory in Hitachi.
