The 1545 siege of Takatō Castle, saw Takeda Shingen continuing his sweep through the Ima Valley of Shinano Province, seeking to take control of the entire province. He defeated Takatō Yoritsugu, the castellan.
== History == Yoritsugu had relied on support from his allies, Ogasawara Nagatoki and Tozawa Yorichika, who failed to aid in his defense. This marked the first time Takatō castle had been besieged.
