Eh, the Japanese really like their way of life. They don’t want their culture to change. If they’d rather disappear from the face of the Earth than accepting foreigners, I think they’re free to do so. Personally, as a Japanese-Canadian, I think it’s stupid and they should at least allow dual citizenship so they’d get “immigrants” with actual ties to the country, but they don’t even wanna do that. So fuck it, let them do their thing. It really isn’t up to anyone else to say they “need” immigrants, imo.
