Imagine 2 Japans:
The cities will have half-black mongrels as well as half-jeets and half-muzzies. Most probably can't speak jap very well so they use pidgin.
The other Japan will be the small villages and towns where the full-blooded japs escape to but of course the half-breeds will want to barge in. Probably the half-whites will want to live there but the japs will probably exclude them too.
The social dynamics playing out would be glorious.
