上田城
In 1586, the Hōjō clan try to take Numata Castle once more, but again are repelled. Tokugawa forces also gather and march towards Ueda Castle again, but Toyotomi Hideyoshi interposes. At this point, Hideyoshi's political presence in Japan is too strong for the Tokugawa clan to oppose, and at his mediation, the attack is called off. However, he also designates Masayuki as a back-up power to the bigger Tokugawa forces in the region. This effectively means that Masayuki now responds to Tokugawa Ieyasu in all military matters.
