What was the previous Tokyo Olympic Games like?

Tokyo was chosen to host 1940 Olympic

This is actually third time Tokyo was chosen to host Olympic Games, because Tokyo was chosen to host 1940 Olympic. But Japan had to give up hosting the games because of the Sino-Japanese war broke out in 1937 and lasted till 1945.　
After Japan lost against Rome to host 1960, Japan was finally chosen to host 1964 among Detroit (became a candidate city seven times), Viennese (became a candidate city once) and Brussels (became a candidate city twice).　Number of votes obtained are Tokyo: 34, Detroit: 10, Viennese: 9 and Brussels: 5.
