Yoshinobu, a long-time vassal of the Matsudaira and Tokugawa clans, governed Hamamatsu Castle on behalf of the Tokugawa house. During the clashes between the Imagawa, Takeda, and Matsudaira clans, he served in the garrison of Nagasawa Castle and in 1562 took part in raids under the command of Itakura Shigezane. When, in 1563, a revolt of the Sōtō-shū sect followers broke out in Mikawa Province, Yoshinobu joined the rebels together with Honda Masanobu and Hachiya Sadatsugu.
The uprising was suppressed, and Yoshinobu, like the other former vassals, was captured alive by Ieyasu’s forces. Later, Ieyasu showed mercy, pardoned Yoshinobu, and restored him to service. During the Battle of Mikatagahara, he gave his life for his lord: posing as Tokugawa Ieyasu, he charged toward the advancing Takeda forces, allowing the real Ieyasu to escape the battlefield. Ieyasu never forgot Yoshinobu’s sacrifice and looked after his son, Natsume Yoshitsugu. During the Osaka campaign of 1614, he told Yoshitsugu: “If not for your father, I wouldn’t be standing here alive today.”
