On May 6, 1837 he became a "rōjū", in which position he often clashed with senior "rōjū" Mizuno Tadakuni over the provisions of the unpopular Tenpō Reforms, especially the "Agechi-rei" which was to have "daimyō" in the vicinity of Edo and Ōsaka surrender their holdings for equal amounts of land elsewhere, thereby consolidating Tokugawa control over these strategically vital areas. After Mizuno was deposed from office, Sukemoto promoted the interests of Tokugawa Nariaki. However, one of Nariaki's first actions was to replace Sukemoto, who was asked to retire on July 20, 1841.
