That’s true for most of the developed world though. And honestly that’s what’s actually required because the planet can’t sustain this level of consumption from this many people so the population actually does need to go down.
Completely agree about the birthrate needing to decline, however Japan is in a worse position due to Japan’s fertility rate stands at 1.3, while the United States is at 1.6. US also some what plugs the gap with significantly higher legal and illegal immigration than Japan. Japanese tend to live longer as well. So they are ending up more lopsided than the US when it comes to age spread.
Not enough to keep their population stable apparently
