Siege of Kanbara

The 1569 siege of Kanbara was one of many sieges undertaken by the Takeda clan against the territories of the Hōjō clan during Japan's Sengoku period. Takeda Katsuyori, the son of clan head Takeda Shingen, led the siege against Kanbara castle in Suruga province, which was held by a garrison of 1000 men under the command of Hōjō Sōun's nephew Hōjō Tsunashige.

The castle fell on 6 December 1569.
