The Siege of Terabe Castle occurred in Eiroku 1 (1558) at Terabe Castle in Mikawa Province. This is notable as the first experience in battle for Matsudaira Motoyasu (later known as Tokugawa Ieyasu).
In 1558, Suzuki Shigetatsu (Hyūga-no-kami) defected from the Imagawa clan and switched his allegiance to Oda Nobunaga. The Imagawa clan responded by dispatching Matsudaira Motoyasu and others to confront him. On 2/5, these forces, together with additional forces led by Sakai Tadanao, the lord of Ueno Castle, attacked Terabe Castle. After setting fires, Motoyasu captured the castle and the Suzuki clan submitted to the Imagawa again. The Terabe-Suzuki avoided extinction and at some time later made a comeback.
The bushō participating on behalf of the Matsudaira included, in addition to Motoyasu, Sakai Tadanao, Ishikawa Kiyokane, Honda Shigetsugu, Honda Shigeharu, Matsudaira Shigeyoshi, Matsudaira Shigemochi, and Nagura Sōsuke. Shigeharu, Shigemochi, and Sōsuke all died in the battle.
