He was the second son of Satake Yoshizumi of Kubota Domain and his mother was the daughter of Matsudaira Naomasa of Matsue Domain. He married the daughter of Sōma Masatane when he was adopted as heir. He was presented in formal audience to Shogun Tokugawa Tsunayoshi as the son of Satake Yoshizumi in December 1692, and was adopted into the Sōma clan in July 1696. After a second audience with Shogun Tokugawa Tsunayoshi in December 1696, he was granted the courtesy title of "Zushō-no-kami". He became "daimyō" in February 1701 on his Masatane's retirement. In 1708, his courtesy title was changed to "Nagato-no-kami". He retired a year later in 1709, turning the domain over to Masatane's real son, Takatane and died in 1711 at the age of 35.
