Because Japan's population problem isn't a wealthy nation problem it's a population collapse problem. It's not just that birth rates have gone down because the average Japanese person has become wealthier or more educated. It's also that the lost decades made raising more kids unfeasible for a generation and because of that there's now a large elder population that must be taken care of by a smaler population. Immigration at least ameliorates some of that problem, plus the economy is doing better which means people will have more time and wealth to raise kids.

Even if you can't reverse the population decline you can at least not make it a dramatic collapse and go through all the human suffering that entails.

All developed countries have falling fertility rates, most below the replacement rate. Japan used to be the poster child for the issue, now they're not even the worst example. How many tens of millions of migrants would be needed to offset the unbalanced age pyramids in Japan, China, South Korea and all the Western countries beginning to experience the same problem? How could such a massive number of people integrate into a country?

The reason people don't have kids is not just the cost of doing so but the massive commitment it entails. People have more agency and mobility than they did before and they don't want to give that up. Importing people and ignoring that is printing more money to pay off current debts.

Now do the same narrative for Germany and Singapore and Korea who are on the same slope
