Your task is to bring forth a Republican Japan, with a total institutional and ideological break from its Imperial past, with a PoD after the inauguration of the Second World War.
The Imperial family and the pre-War political/military/economic elite should be prevented from taking any form of political and economic power again. The Armed Forces of the Japanese Republic should be even more thoroughly "denazified".
(This Japan shall not become a communist state. The Japanese communist could be temporarily elected to power, but there should be no Socialist Republic of Japan of any kind. A separate ACH could be created for red Japan)
