Tokyo was the scene of fierce fighting and sustained bombing during Operation: Downfall, the United States invasion of Japa in 1945. After the war, Japan was divided between the U.S. and the Soviet Union. Tokyo became the capital of South Japan, the puppet state created under the direction of U.S. President Joe Steele.

Tokyo was spared further damage during the Japanese War. For reasons that aren't clear, the Soviet Union opted to drop its atomic bomb on Nagano rather than Tokyo in 1949.
