Takeda Shingen
In 1568, Ujiteru defended Takiyama castle from Takeda Shingen. Later in 1569, Ujiteru and his brother Hojo Ujikuni commanded a major force at the Battle of Mimasetoge, where they unsuccessfully attempted to prevent Takeda Shingen from withdrawing to his home province of Kai after besieging the Hōjō's core castle at Odawara.
