北條氏康
Subsequently, Ujiyasu managed to make peace with Uesugi Kenshin and Takeda Shingen, the most powerful adversaries of Hōjō Ujiyasu, letting his seventh son Hōjō Saburō be adopted by childless Kenshin and accepting the "fait accompli" of Shingen's reign over Suruga. To cement the ties of Takeda-Imagawa-Hojo, Ujiyasu also gave his two daughters to those two clans; Lady Hayakawa wed to Imagawa Ujizane, while Lady Hojo (Hojo Masako) wed to Takeda Katsuyori becoming his second wife. Ujiyasu died in 1571, passing on the Hōjō domains to his eldest son Ujimasa (北条 氏政) in a relatively favourable situation.
