So Japanese racial superiority moderates down to Japanese cultural exceptionalism, at least it seems that way to me. It's both laudable and eyebrow-raising, the latter because since Japanese will be accepting assimilates unlike in OTL, Japanization will suddenly become more successful and appealing. Japan's Manchurian and Korean and other colonies may still get Home Rule, but if they stick around for too long, they're never going to get independence, at least not without a lot of internal strife ala Northern Ireland vs Ireland.
In a way, this Empire of Japan is more dangerous than the OTL Empire of Japan, because they can play the game the OTL empire could not.
