Were it not late I would respond with Japanese land area, natural resources, almost entire dependency on imports, natural disasters, current account deficit and an entire country ravaged after being the losers in the last global war, including the only place on Earth to be ever attacked with nuclear weapons. I'm not of the opinion that many poorer countries would also be capable of fighting for worker pay were it adjusted for what is clearly national potential.

And while not addressing your clearly correct comment, I'd far prefer to be a remote worker in Osaka or Tokyo than virtually all cities in the US despite language/cultural difficulties.
