Presumably I'm the cause of the flickering politico meter
I think what I said is true, however. We must not forget that Japan was a good fix with the Axis. They had engendered a feeling of racial superiority and a sort of manifest destiny for Asia. Years of propaganda (within education as well) resulted in a feeling of racial superiority that mirrored that of Nazi Germany. The brutalization of "lesser" peoples was the unambiguous result of this kind of racism. Germany owned (and owns) theirs, post war Japan, never really has, sadly.
There is another analogy to Germany. When Germany invaded the Soviet Union, there were indeed many who welcomed them (in France, too, actually

). The Nazis blew any good will they had very quickly, of course, once the locals got to know them.
I think that a scenario where the primary focus of Japanese military action is INDIA is an interesting one. The military being used to eject thye British in return for an Indian Client State (protectorate, whatever).
