> Sure, societies evolve, but they evolve together. Introducing heterogeneity is an entirely different thing. As I just said, Japan suffered a brutal defeat in a World War, with two atomic bombs, losing sovereignty for ~7 years, military leaders getting executed for war crimes, foreign military bases sprouting everywhere (which still exist), and the monarch reduced to a symbolic role. And arguably Japan is better for that and I doubt most Japanese people would want to go back to the glorious days of Japanese Empire even if they could. So I don't really get this phobia of how Japan allowing a few million immigrant workers at almost the lowest level of the societal ladder would ruin its culture. Like, exactly what concrete part of Japanese culture do you expect to be ruined? Light novels?
