That's the closest thing to a plausible in-universe answer I can come up with. I mean, there are still a few individuals that are blatantly foreign. Though frankly, it's more likely that it's just an arbitrary choice since Kubo is (obviously) Japanese himself. and ofcourse is imposible to knwo how other countries look like or maybe live like :P
