In addition, Minami outlawed all but one of the Korean language newspapers, and strongly pushed for the "soshi-kamei" policy. After his term in Korea, Minami served as a member of the Privy Council from 1942 to 1945, and had a seat in the House of Peers in the Japanese Diet in 1945. After World War II, Minami was arrested by the American Occupation authorities and brought before the International Military Tribunal for the Far East. He was convicted only of Counts 1 and 27: i.e. of being a leader in the plan to wage an unprovoked war of aggression against China, largely since he was Minister of War at the time of the Manchurian Incident. However he was acquitted of waging a war of aggression against the United States, the British Commonwealth and the Netherlands, and also acquitted of two charges related to prisoner abuse. He was sentenced to life in prison but was paroled in 1954 on the grounds of his health. He died a year later.
