Tokitada was an important retainer of the Satomi and was active in the latter's efforts to subdue the Boso area, assisting in the war with the Takeda of Kazusa. He captured a number of castles between 1550 and 1560, including a number in the Chiba's domain. Following the Satomi defeat at 2nd Konodai (1564), Tokitada rebelled. He later submitted and supported the Satomi until his death in 8/1571.
