Komatsuhime
Life. Komatsuhime was known in her childhood as Inahime (稲姫) and also Onei (於小亥). After witnessing the martial prowess of the Sanada at the First Battle of Ueda Castle, she and her father were captivated by them. Tokugawa Ieyasu himself arranged for Komatsuhime to marry Sanada Nobuyuki, the son of the Sanada lord. 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. After the Battle of Sekigahara, during Masayuki  and Yukimura's exile, she took charge of sending them food and other daily necessities. Komatsuhime was praised as a good wife and wise mother ("ryōsai kenbo" 良妻賢母). She died in Kōnosu, Musashi Province (the present-day city of Kōnosu in Saitama Prefecture) at age 47, while en route to the Kusatsu hot spring. Nobuyuki lamented her death, saying that "the light of my house has been extinguished." Her grave can be found there. Today, in the museum at Ueda Castle, visitors can see items that she used, including her palanquin. Cultural references. Inahime is the namesake and partial inspiration  for Princess Ina in the novel "Mercy of the Elements".
