On November 30, the Emperor Showa asked Shimada if he would really wage war. Shimada said, "We are ready, I do not trust Germany, I mentioned that Japan alone can continue the war."
After a series of major Japanese losses,
Emperor Hirohito lost confidence in both the Army and Naval Chiefs of Staff. As such, Tōjō was able to dismiss Chief of the Army General Staff
Hajime Sugiyama and Chief of the Naval General Staff
Osami Nagano. Tōjō assumed the role of Army Chief of Staff while Shimada became Naval Chief of Staff on 21 February 1944, concurrent with his position as Naval Minister. This reorganization made Shimada supreme commander of the Imperial Japanese Navy.

Shimada's opponents continuously pressured Emperor Hirohito to dismiss him, citing that the navy was losing battle after battle under Shimada's direction.
