Suwa Mitsutaka served as a bushō during the Sengoku period. Mitsutaka was the third son of Suwa Yorimitsu. His common name was Satsuma-no-kami.
As the uncle of Suwa Yorishige, Mitsutaka and his older brother, Suwa Mitsuchika, supported Yorishige, but, in 1542, after Yorishige was attacked by Takeda Shingen, the Suwa fought back to no avail and lost, surrendering to the Takeda. Mitsutaka joined in putting down a rebellion by Takatō Yoritsugu and Yajima Mitsukiyo who had aimed to restore their rights in Suwa. In 1546, after a child (Suwa Katsuyori) born to Suwa Goryōnin and Takeda Shingen was designated as the successor to the Suwa family, Mitsutaka opposed the decision and launched a rebellion, but it was suppressed and he was ordered to commit seppuku.
