They are going to need to manage that. Japan is overpopulated and too expensive. The right people need to think about new models and processes for population decline. Bringing in foreigners is the solution people throw out. Why the hell wouldn't you want to shrink things down and embrace what can be done with that?

They need to slow population decline but a decline is good for that country for a little while. Way too many people, too long of lines. They need more leisure time and less stress there.
