While assigned to the naval torpedo school and working on a motor-torpedo-boat programme, Hara concluded that Japan could no longer overcome its technological disadvantage. He wrote a wartime letter urging Emperor Hirohito to dismiss the heads of both the army and navy because the war was lost. The warning reached the emperor's younger brother at the Navy Ministry, providing a route into the court while exposing Hara to obvious personal risk. The episode links a destroyer officer's technical work to a strategic judgment about the state's ability to continue the war.
