Rebuilding is not a problem. It is the birth rate that is a problem. Tokyo is vacuuming everyone from countryside. You get some refugees in their 30s moving back but it is a trickle.

This fund is a typical Japanese corporate bullshit. You can see who manages it an know everything you need to.

They could just pay 10mil yen stipend per child after second and it would be far more effective. Japan needs young people, period. Not more taxes, infrastructure etc

I lived in Japan for a while, loved it. But the crash when it comes in 10-20years as countryside disintegrates is going to be horrific.
