Japanese folks have always been xenophobic. Like, thats not new at all, and their immigration rates are comically low compared to other countries. With their birth rate falling off a cliff for decades, they need more people one way or the other. So immigration opens up a bit because they need warm bodies. Thus we see anti immigrant parties rise... but they can't fix the core issue of nobody bumpin uglies either, because they don't or can't fix the why behind that (Two incomes required, both doing 80 hour weeks at their companies.) So its either get some more brown people in the country or eventually have no one left, and sadly I think some Japanese folks would prefer the latter.
