 In 1756, his young nephew Date Shigemura became "daimyō" of Sendai, and Murataka was appointed to act as guardian.His tenure was marked by repeated crop failures caused by cold summers and drought, which drove the domain to the edge of bankruptcy, and he had to turn to Sendai Domain for financial assistance on three occasions.On his death at the age of 46 in 1782, he was succeeded by his grandson, Tamura Murasuke.
