Oyama
The Oyama were a warrior family based in Shimotsuke Province, where Masamitsu settled at Oyama around 1150. In 1333 Oyama Hidetomo joined Nitta Yoshisada's attack on the Kamakura shogunate.
Oyama Yoshimasa became governor of Shimotsuke, but his struggle with the Utsunomiya culminated in the killing of Utsunomiya Mototsuna in 1380. The Kamakura authorities sent an army against him; after renewed resistance, Yoshimasa killed himself in 1382.
