Second son of the daimyo Satake Yoshishige, he became the 20th head of the Ashina Clan when he married Ashina Moritaka's daughter. However, he lost the Ashina lands to Date Masamune after the betrayal of one of the Ashina's key vassals at the Battle of Suriagehara in 1589. He then fled to Hitachi and was later given land there by Toyotomi Hideyoshi.
