Of peasant birth, he was discovered by Shingen and rose to the Takeda Four Guardians. His skilful withdrawals that kept losses low earned him the name "the retreating Danjō." Entrusted with Kaizu Castle, the front line at Kawanakajima, he was the first to detect the Uesugi movements and set the woodpecker plan in motion. The Kōyō Gunkan, the military chronicle of the rise and fall of the Takeda, is said to be based on his dictation.
