Location
Cause → Event → Consequence
Katsurayama Castle was a strategically vital Uesugi stronghold in contested Shinano Province. In early 1557, heavy late-season snow cut off the castle garrison from Uesugi reinforcements, presenting Takeda Shingen with an opportunity to strike an isolated enemy position during the broader Kawanakajima campaigns.
Takeda forces under commander Baba Nobuharu besieged Katsurayama Castle in March 1557. Despite fierce resistance by the combined Ochiai and Murakami clan garrison, the Takeda army eventually stormed the fortification, overwhelming the defenders in close combat and seizing the castle.
Most of the castle's garrison was killed fighting, while the families of the defenders took their own lives in mass suicide. The castle itself was burned to the ground, eliminating a key Uesugi position in Shinano Province and strengthening Takeda control over the region.
