It is difficult for me to comment on issues of grave concern to the Japanese polity and I feel your first question is adequately answered (including in English) by appropriate Google searches, so I’d encourage you to make those Google searches. Your suggestion with regards to policy is materially outside of the present Overton window and almost all of my models for the Overton window in 10 years.
Suggestions which are much more inside the Overton window include gradually making Japan more hospitable to immigrants, which a) has already happened to a degree far underappreciated ex-Japan b) is more palatable to power than people model it as and c) would still have many kilometers to go to address long-term demographic trends.
