The Tenshō-Jingo conflict is a collection of battles and posturing between the Hōjō, Uesugi, and Tokugawa after the death of Oda Nobunaga. The campaign began with the Hōjō driving out the demoralized Oda forces under Takigawa Kazumasu. The Hōjō managed to capture Komoro castle, placing it under Daidoji Masashige. They pushed further into Kai, capturing and rebuilding Misaka Castle as they squared off against Ieyasu, who had made inroads by absorbing former Takeda officers into his army. Takigawa Kazumasu lost decisively against the invading Hōjō army at the Battle of Kannagawa and on July 9th, Masayuki defected to Hōjō's side. Meanwhile, Uesugi forces were invading northern Shinano. Both armies came to face each other at Kawanakajima on July 12th, but direct combat was avoided as the Hōjō army turned back and advanced south towards Kai province, which was in turn invaded by Tokugawa forces. At one point, the Hōjō clan had come close to controlling most of Shinano province, but Masayuki helped Yoda Nobushige, a local lord who had been resisting against Hōjō's advances in Shinano and was in touch with Tokugawa Ieyasu. He then defected to the Tokugawa's side on September 25. Faced with this sudden betrayal, Hōjō Ujinao saw his position in the conflict weaken and decided for a peace treaty and alliance with the Tokugawa clan, which was agreed upon on October 29th. This event marked the end of the conflict which lasted for roughly 5 months after Nobunaga's death.
