Imperial Japanese Army Imperial Japanese Navy Prime Minister of Japan Hideki Tojo Isoroku Yamamoto Nagato its military forces Italy Tripartite Pact
Japan's military leaders were divided on diplomatic relationships with Germany and Italy and the attitude towards the United States. The Imperial Japanese Army was in favour of war with the United States, but the Imperial Japanese Navy was generally strongly opposed. When Prime Minister of Japan General Hideki Tojo refused American demands that Japan withdraw its military forces from China, a confrontation became more likely. War with the United States was being discussed within the Japanese government by 1940. Commander of the Combined Fleet Admiral Isoroku Yamamoto was outspoken in his opposition, especially after the signing of the Tripartite Pact, saying on 14 October 1940: "To fight the United States is like fighting the whole world. But it has been decided. So I will fight the best I can. Doubtless I shall die on board Nagato [his flagship]. Meanwhile, Tokyo will be burnt to the ground three times. Konoe and others will be torn to pieces by the revengeful people, I [shouldn't] wonder. " In October and November 1940, Yamamoto communicated with Navy Minister Oikawa, and stated, "Unlike the pre-Tripartite days, great determination is required to make certain that we avoid the danger of going to war. "
