>or example their unwillingness to sacrifice cultural homogeniety on the altar of economic growth.
Every time I hear this argument (and it comes up in just about every thread about Japan's economy or culture) I can't help but hear an alt-right dog whistle.
Because, of course, Japan has a long history of incorporating culture from elsewhere - both from their Asian neighbors and the West, but when you talk about "homogeneity" in relation to Japan, people tend to think first about ethnicity and race, since they're ~98% ethnically Japanese.
And I'm not entirely certain can I see the link between "cultural homogeneity" and "economic growth" ... until I realize you're talking about immigration. Which is odd because most immigrants to Japan are Asian, and not likely to disturb their "cultural homogeneity" much, and the tiny, tiny fraction from elsewhere are definitely not likely to do so.
Maybe that's just me and my cooling fan is acting up, though.
