I think the point there is that immigration is used as a way to paper over the fact that living conditions in a country discourage people from actually having kids. It would not be necessary if people had maternal leave, sufficient time to raise children, social services, and so on.
Which simply means that those countries also have societal pressures which favor not having children despite the measures they may be taking. Birth rates don’t decline because of magic, it’s a response to systemic pressures. It should be obvious that it’s possible to create different pressures within the society that favor different choices.
You have to be full blood Japanese to be considered Japanese and to be a citizen. So any Japanese who marry someone not Japanese is a large net loss for the society. Plus it’s impossible to become a citizen through immigration unless you’re somehow full blood Japanese.
Why would racism make their population collapse? That has more to do with birthrates and quality of living.
Immigration can compensate for that, in countries that allow for immigration.

Many countries have those things and it has had no effect on birth rates.
Once birth rates start declining it doesn’t seem to be reversible within a single generation.
