Oyamada Nobushige

Oyamada Nobushige (小山田 信茂, 1545 – April 16, 1582) was a Japanese samurai general in the Takeda army under Takeda Shingen, and later under Takeda Katsuyori. He was known as one of the "Twenty-Four Generals of Takeda Shingen". He was also lord of Iwadono Castle, and fought under the Takeda at the battles of Kawanakajima, Mikatagahara, and Nagashino and Temmukuzan.

Oyamada betrayed the Takeda clan in 1582; however, when he went to the Oda clan camp, he was executed by Oda Nobunaga's officer Horio Yoshiharu.
