Biography
Satake Yoshimasa was the eldest son of Satake Yoshikata of Kubota-Shinden Domain and was adopted as heir to Satake Yoshizumi in 1742. He was received in formal audience by Shōgun Tokugawa Yoshimune in 1744, and became daimyō of Kubota in 1749. In 1751, he married Gōhime (1737-1762), the daughter of Maeda Yoshinori of Kaga Domain and he made his first visit to his domain the same year. Kubota Domain was rent by peasant uprisings and by plots among his retainers caused by the years of mismanagement of the domain by his predecessor. Yoshimasa died at Kubota Castle in 1753 after complaining of sudden stomach pains and growing numbness in his limbs. During the Edo period it was widely suspected that he had been poisoned. As he had no children, the domain passed to Satake Yoshiharu, the eldest son of Satake Yoshimichi of Iwasaki Domain.
