So, after WWII, Germany was split into 4 occupation zones, with each main European ally occupying a part of the country. My main question is, why wasn't a similar thing done with Japan? I know at least Britain played a fair role in the war in the pacific as well, and China put up a good fight against Japan too. I think the USSR helped at the end as well. I also know there was American military occupation, but no occupation zones. Why wasn't Japan divided between these countries (China, USSR, UK) and the US the same way Germany was? Was it to do with a cultural difference in Asia, or the geography of Japan, or simply because it was deemed unnecessary by the Allies?
