In August 1180, using Kamakura as his headquarters, Minamoto no Yoritomo sent his counselor, Hōjō Tokimasa to convince the warlords Takeda of Kai and Nitta of Kotsuke to follow Yoritomo's command as he marched against the Taira. As Yoritomo continued through the region below Mount Fuji and into Suruga Province, he planned a rendezvous with the Takeda clan and other families of the provinces of Kai and Kōzuke to the north. These allies arrived at the rear of the Taira army in time to ensure a Minamoto victory.
