1- The restrictions are not about race, but about which countries have mismanaged the pandemic. People from Taiwan and some other south east asian countries are allowed to enter. (Ironically, exactly those people are / have been much more commonly the target of Japanese racism).
2- They most likely would prefer to also ban Japanese citizens (whatever race) from returning from hot-spots like Florida or Brazil. They just can't because of legal reasons. Citizenship gives you certain rights.
3- You can call PR and other visas "second class citizenship" if you want, but the fact is: you're just not a citizen. You also can't vote. You also can't become prime minister. You're not a citizen and don't have the rights of a citizen. That's the same in every country, including yours. Why didn't people with PR complain about being "second class citizens" for years about those other rights?
I think it’s pretty clear that if you plan your life in a secondary country, and they allow you to via permanent residency, you would not want them to lock you out at a whim.
1. The people that choose to live in Japan are well aware of this fact and consider it to still be a good place to live. Japan is a very unique place.
2. There is a difference between Permanent Residency and Citizenship.
The post is about acquiring residency, not citizenship.
>Aware of foreign residents’ concerns, Prime Minister Shinzo Abe said last month that Japan would loosen some of the rules. On Wednesday, immigration officials said at a news conference that they had begun readmitting those who left before the start of the restrictions in April.
