Other comments had it so I didn’t think it was necessary. Immigration can prop up a low birthrate but that can’t last forever. Need to actually have a culture that supports procreation. And Japan doesn’t really have that. Their work culture is directly responsible for it. I don’t think that’s something easily fixed. Financial incentives could help, but unless it’s pretty hefty it probably wouldn’t be enough.
Oh? You could optionally expand instead of just stopping at what the problem isn’t.

Australia had a baby bonus for a while. It was a payment you’d get for giving birth to a child. I believe it was like $3K.
