→Lord of Takiyama Castle · Lord of Hachiōji Castle
Hōjō Ujiteru (c. 1540-1590), son of Hōjō Ujiyasu and younger brother of Hōjō Ujimasa, was one of the leading military commanders and diplomats of the late Hōjō of Odawara. Adopted around 1546 by the Ōishi family, under whose name he first served, he inherited their lands in the Tama region. Lord of Takiyama Castle from around 1561, he defended it against Takeda Shingen in 1569, and in the 1580s he had the mountain castle of Hachiōji developed. He moved there around 1582-1587, and it became the most important secondary stronghold of the clan. During the Odawara campaign of 1590, Hachiōji fell in a single day while he was at Odawara; after the surrender, he took his own life together with his brother Ujimasa on the orders of Toyotomi Hideyoshi.
Guardian of the western frontier of the Hōjō domain facing the Takeda's Kai province, Ujiteru first held Takiyama Castle, which resisted Takeda Shingen in 1569. In the 1580s, he had built on Mount Fukasawa a larger and better-defended mountain castle, Hachiōji, equipped with stone walls and a lord's residence at the foot of the hill.
