Kiyoshige of Shinano province was related to the Kasahara who served the Hôjô. Kiyoshige resisted the advances of Takeda Shingen and was besieged in Shiga castle in 1546. Uesugi Norimasa sent a relief army but this was defeated at Odaihara and Shingen displayed the heads taken at that battle before Shiga to dishearten the defenders. In 1547 the Takeda forced their way into Shiga and Kiyoshige was killed. His wife and children were taken as prisoners by the Takeda to Kai while a relative named Kasahara Noto no kami Mitsusada fled to the Hôjô domain and took up there.
