and seized the opposite bank of the Tama River. However, the true purpose of the attack was feint in an attempt to draw off Hōjō forces from Shingen's real target, which was Odawara Castle. Although Shingen managed to encircle and threaten Odawara for a week, he eventually gave up and returned to Kai Province, and the forces at Takiyama Castle were also withdrawn. One result of the battle was that it revealed to Hōjō Ujiteru critical weaknesses of Takiyama Castle.

Furthermore, the location of the castle proved that it was not an obstruction for Takeda army to attack the Hōjō home territory at Odawara. Therefore, a few years after the battle, Hōjō Ujiteru relocated to
