上田城
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.
