Fushimi held various line and staff duties, and he was promoted to full admiral in 1922. He occupied the post of chief of the navy General Staff from 1932 to 1941. Fushimi opposed the naval tonnage ratio fixed at the Washington Conference of 1921–1922. His support of the so-called Fleet Faction encouraged the hard-liners to push to increase their influence in the navy during the late 1930s.
During this period, Fushimi took over many of the functions traditionally under the jurisdiction of the navy ministry. He also saw to it that many high-ranking naval officers who had supported the Washington Naval Treaty of 1922 were dismissed from the service. Replaced by Nagano Osami in April 1941, Fushimi thereafter had no practical influence on affairs of state or the war. He died in Tokyo on 16 August 1946.
