Genealogy (selection)

  • Masamitsu (政 光), a descendant of the 14th generation of Hidesato, was the first to call himself Oyama in the mid-12th century , after the castle in Shimotsuke Province , which the Oyama had inhabited for three hundred years.
  • Tomomasa (朝政; 1155–1238), Masamitsu's son, immediately followed Minamoto Yoritomo when the latter raised an army against the Taira . As a reward, he received several domains in Hitachi Province . He fought in the battle of Ichi-no-Tani and took part in the 1189 campaign against Fujiwara no Hidehira (藤原 秀 衡; 1096-1187). The following year he accompanied Yoritomo to Kyoto and became Kebiishi and Shimotsuke no Kami (下野 上), then in 1199 governor (守護, Shugo) of Harima Province . Then he struck down, together with Hatakeyama Shigetada (畠 山 重 忠; 1164-1205), the rebellion of Hiki Yoshikazu († 1203) against the Hōjō .
  • Hidetomo (秀 朝; d. 1335), descendant of Tomomasa in the 6th generation, fought under the Hōjō against Emperor Go-Daigo and besieged Akasaka Castle (赤 坂 城). He then joined Nitta Yoshisada , defeated Kanazawa Sadamasa (金澤 負 將) at Tsurumi in Musashi Province and took part in the siege of Kamakura . During this time he was appointed Shimotsuke no Kami. In 1335 he was killed in Musashi while fighting against Hōjō Tokiyuki (北 条 時 行; 1322-1353).
  • Yoshimasa (義 政; died 1382), Hidetomo's grandson, mustered an army in 1380 when it came to defending the south courtyard and defeated Utsunomiya Mototsuna near Mobara. Then he had to withdraw from Uesugi Norikata (上杉 憲 方; 1335-1394), who had been sent against him by Kanryō Ashikaga Ujimitsu (足 利 氏 満; 1359-1398). He attacked again soon after, but was defeated by Uesugi Tomomune and committed seppuku .

With Yoshimasa's death, the family died out.
