The 1545 siege of Ryūgasaki was one of many battles fought by Takeda Shingen in his bid to control Shinano Province during Japan's Sengoku period. The fortress was a satellite castle of Fukuyo, and was held by Tozawa retainer Yoshinaga Mitoyoshi. Yoshinaga himself was killed in battle while the fortress fell.
