Perhaps the USSR and Japan signed a peace treaty in order for the Soviet Union to attack and defeat Germany, giving them Siberia maybe. Japan may then last until the modern day. They wouldn't be as developed as they are in OTL would they. There would also be a lot of riots in Japanese colonies and a lot of racial discrimination and violence by the Japanese government. Perhaps in the late twentieth century this ruling style causes communist paramilitary groups supported by Stalin to rise up against Japan. Another Soviet Japanese war might start. Perhaps hatred of Japan by the West and Russia might be what causes the Cold War to cool.
