After losing Iwatsuki Castle to Hōjō Ujitsuna, Ōgigayatsu Uesugi Tomooki allied even with his old rival Yamanouchi Uesugi Norifusa and with Takeda Nobutora to resist the Hōjō. Yet Norifusa himself fell ill amid the ongoing conflicts with the Hōjō, Ōgigayatsu, and Takeda, and died, throwing the balance of power in the Kantō region into disarray.
