I'm not sure if anyone cares about this anymore, but ethnically Japanese people will become nearly extinct if they don't make some radical changes. They should massively incentivize people - even financially poor Japanese - to have kids. Just because someone has a career in e.g. a Japanese bank moving spreadsheets around doesn't mean they should be favored.
Hungary has already tried this and it doesn't work.

Evidently much more is required. Or it could be that the problem isn't solely financial. In heavily urbanized countries, most people apparently prefer easy modern entertainments to the rigors and stresses of parenting.
If they’re serious then make the incentives serious, and scale.
Perhaps there should be a tax that starts at age 19, and increases in percentage the longer you don't have children. I am also not sure if it's better to only tax women (since they are the ultimate gatekeepers) or men as well.
If you do have children, especially 2 or above, the government should pay you dividends in some form along with other benefits.
Good luck passing any laws that put elderlies at a clear short term disadvantage ("the country will be better for it in 20~30 years" won't resonate much to a 70 yo couple)
Punitive taxes on the childless would just ensure that the ones waiting for prudential reasons (savings, home ownership) would be even less likely to take the plunge.
Maybe the people who have kids should rake in dividends from the people who don't have kids.
