Yorishige was a son of [[Suwa Yoritaka]] [諏訪頼隆] and succeeded his father when the latter died in 1539. He ruled the area about [[Lake Suwa]] in [[Shinano province|Shinano Province]]. In [[1540]] the Suwa and their rivals the Takeda of [[Kai province|Kai Province]] made peace and Yorishige married the daughter of [[Takeda Nobutora]], [[Nene]]. The following summer he joined Nobutora and [[Murakami Yoshikiyo]] in attacking [[Unno Munetsuna]]. Shortly after that, Nobutora was banished from Kai by his son, [[Takeda Shingen|Harunobu]], and the Takeda-Suwa alliance was rendered moot. Yorishige and [[Ogasawara Nagatoki]] joined forces to invade Kai but were repulsed by Harunobu. 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 brought back to Kai and confined at the [[Tokoji|Tôkoji]] in Kofu. He was forced to commit suicide along with his brother [[Suwa Yoritaka|Yoritaka]] [頼高] on 1542/7/21, although he may possibly have been murdered. His daughter was taken as a concubine by Shingen and produced the eventual head of the Takeda, [[Takeda Katsuyori|Takeda (Suwa) Katsuyori]]. His son was spared and was taken to Kai along with his mother. He eventually became known as Chôkyuu [長岌] and his eventual fate is unknown.
