Well, the same kind of cultural effects among the young exist in the Western world (the youth want to live in cities, not reproducing as much, problems with suicides, etc) and these are countries that are open and welcoming to foreigners and try and respect everybody of every race/gender/etc.

Therefore, I'm not seeing a strong case for Japan's problems being caused by them not being welcoming to foreigners because other countries are welcoming to foreigners and still have these problems in greater number today.
