> It is actually quite hard to raise the birth rate, Japan has been trying for years

Not...really.

> UN report on Japan's birth rate policy attempts:

And details defects in the specific policies (notably, these defects are, one who is familiar with policies of the type will notice, ways they fall short of the support policies in many European countries that aren't even specifically trying to boost birth rates.)

E.g., a paid family leave policy with low payments and lacking legal force, so many employers haven't actually implemented it.

This is a government making a pro forma show of “doing something” about a problem, not a serious policy effort.
