上田城
In 1600, when Nobuyuki had decided to cast his lot with the Tokugawa, his father Masayuki (who had not done so) was en route to Ueda Castle, accompanied by his other son, the famed Sanada Yukimura. The two stopped at Numata Castle, where Komatsuhime was managing affairs. Komatsuhime challenged Masayuki and Yukimura at the entrance of the Castle moments before of the Siege of Ueda. Masayuki relayed a message to her: "I want to see my grandchildren", and in response, the princess emerged, dressed in full battle attire, saying, "Since we have parted ways in this conflict, though you are my father-in-law I cannot allow you into this castle." Masayuki and Yukimura withdrew to a temple, Shōkaku-ji, and were surprised when they saw Komatsuhime (with her children) arrive soon after them, honoring Masayuki's wish.
