Japan's aging society and low birthrate demand dramatic measures, some say.

A 2000 UN report stated unequivocably that Japan must import 600,000 workers per year to maintain fiscal balance. A Prime Ministerial commission that same year concurred: "Japan should set up an explicit immigration . . . system to encourage foreigners . . . to move in and possibly take up permanent residence here."

Unfortunately, this is not happening. Though about 4.5 million foreigners cross Japan's borders every year, the average annual increase in registered foreigners is only about 75,000. So to keep its taxpayer base young, Japan must make foreigners want to stay, even encourage them to become immigrants or citizens.
