Well...Most Japanese have fair skin anyway, right? China is big, not every chinese have fair skin. And so far...Japanese have always been proud people, they were also colonialist and not the colony...so it's to be expected that this inferiotity complex is not a common problem in their society. They belong to the group who look down on other nation and not the victim.
Japan had sucked Indonesians blood and wealth too for few years until the end of WW II.
