The Japanese were not ready to surrender unconditionally, and that was the internationally agreed endpoint of the war with Germany and Japan. Unconditional surrender and occupation was considered necessary to completely break the German and Japanese spirit and ensure no third world war. The Allies didn’t want a repeat of the inter-war period between WW1 and WW2 where Germany was not occupied and could tell itself that it hadn’t really lost WW1. The Allies agreed that the way to avoid this problem was to comprehensively defeat and then force unconditional surrender on the Axis powers, followed by occupation, re-education, and rebuilding. When you look at Japan and Germany’s success after WW2, it’s hard to argue that the Allies were wrong to take that stance. The atomic bombs are a side issue. The invasion of Japan would have been so much worse.
