Having been a retainer of the Date clan since the time of Harumune DATE, he was given Takahata Castle in Okitama-gun, Dewa Province. He was a wise and courageous man. He achieved military success in combat with Minbu SATOMI who was a busho (military commander) of the Mogami clan and with Sadatsuna OUCHI. In 1570, however, he aroused Terumune's anger when he failed to capture Munetoki NAKANO who escaped. He retired from active duties on account of old age when Terumune DATE died in 1585. He had since given advice to Masamune DATE as the latter's close associate. In his later years he was known as Deibansai. On February 22, 1595 he died in Kyoto. He was 73 years old.
