Japan is a non-immigrant country, can't it apply for permanent residence at most? Why do many people say that they can be naturalized?

1, Japan itself is a contradiction, it is not an immigrant country. In other words, you can't apply for technical and investment immigration directly to the Immigration Bureau like the United States, Canada, Australia and other immigrant countries.

2. But if you have a job in Japan, pay taxes, or have been married to a Japanese for a long time, you can also apply for naturalization. Because Japan needs people who are good for Japan to improve Japan.
