Suwa Yorishige
Yorishige was a son of Suwa Yoritaka and ruled the area about Lake Suwa in Shinano province. He joined with his neighbors (such as Murakami and Ogasawara) to clash with the Takeda of Kai on a number of occasions between 1531 and 1542, although a peace was made through his marriage to the elder sister of Takeda Shingen. In 1542 the Takeda made a sudden attack that caught Yorishige by surprise and brought down both Uehara and Kuwabara within two days. Yorishige was forced to commit suicide on 31 August 1542. His daughter was taken as a concubine by Shingen and produced the eventual head of the Takeda, Takeda (Suwa) Katsuyori.
