Nobushige was the son of Oyamada Nobunari (d. 1552). He served Shingen well and fought in a number of his battles, including Fouth Kawanakajima (1561), Takiyama (1569), and Mikatagahara (1573). Although a distinguished general, Nobushige abandoned Takeda Katsuyori in 1582 when the latter was pressed by an invasion by Oda Nobunaga and Tokugawa Ieyasu. He was criticized by Oda Nobunaga for his treachery and so was executed despite his desertion.
