Sanada clan
The Sanada clan claimed descent from the Seiwa Genji. Historically, the clan's banner was established by Unno Yukiyoshi in the early 16th century. He emblazoned the Rokumonsen on his banner. The Sanada were key vassals in the Takeda army, with three famous generals being Sanada Yukitaka and his sons Sanada Nobutsuna, Sanada Masateru, and Sanada Masayuki.
