I'm near fully sure you were being rhetorical... But I accept the bait !!!  Japan see, doesn't give a rats behind what the Ben&Jerrys-Hagendaaz happy land feeling-dealers west of the 65th think about their Immigration Policies... They don't particularly care for foreigners and don't feel especially guilty about it or about their strict Immigration controls. They (IMHO) have a better solution to the decline of the Native Birth Rate, which would be... ROBOTS!
