as Chief of the Navy General Staff, after the latter resigned, and was the final supreme commander of the Imperial Japanese Navy from 29 May 1945 onward.
Toyoda participated in numerous
Imperial Conferences concerning the
surrender of Japan. Initially, the
Navy Minister,
Mitsumasa Yonai, hoped that Toyoda would be able to exert a moderating influence over Army Chief of Staff
Yoshijirō Umezu (since both came from the same district of Japan). However, Toyoda joined Umezu in his protestations against the
Potsdam Proclamation of 26 July. Toyoda was for termination of the war but insisted that the government push for more favorable terms. After the
atomic bombing of Hiroshima and Nagasaki, Toyoda's position became even more hardline. He argued that the Japanese people should defend the
Japanese home islands until the last man.
Post-war
After the war, Toyoda was interrogated by Rear Admiral
Ralph A. Ofstie in Tokyo on 14 November 1945. He was viewed as "highly intelligent and widely informed", and was observed to be a strong critic of the amount of political power the Army held in the Japanese government. He also expressed his opinion that the war with China should have been ended "even at some sacrifice" so that the men and resources could be redeployed to the Pacific theater.

Toyoda was subsequently arrested by
SCAP authorities and held in
Sugamo Prison. In 1948, Toyoda was charged with war crimes "for violating the laws and customs of war". He pleaded 'not guilty' to all of the charges. He was acquitted and later released in 1949. He was the only member of the Japanese armed forces charged with war crimes to be acquitted.
Toyoda published his memoirs in 1950, and died in 1957 of a
heart attack at the age of 72.
