- Japanese: 友野家 (Tomono-ke)
The Tomono of Shinano province were descended from the Ogasawara family. Their power was weakened by their involvement in the Adachi Yasumori affair (1285). In the Sengoku Period they would become vassals of Takeda Shingen. They became retainers of the Tokugawa when the Takeda fell in 1582.
