Siege of Kaminogō Castle

The Siege of Kaminogō Castle was a battle in 1562, during the Sengoku period (16th century) of Japan. Kaminogō Castle was an Imagawa clan outpost located in eastern Aichi Prefecture, in what is now the town of Gamagōri.

With the help of his ninja vassal Hattori Hanzō, Matsudaira Motoyasu (later known as Tokugawa Ieyasu) laid siege to and stormed the castle. The Matsudaira force captured the castle from Udono Nagamochi, a general of the Imagawa. In taking the castle, Motoyasu obtained many useful hostages to use against the Imagawa, who were then in possession of his own family.
