It is explained here:

and how long do u gotta live in japan before you can apply for it?

As a rule of thumb, 5 years if you are married to a Japanese national or 10 years if not. If have been married to a Japanese national for a long time and made contributions to Japan, it can be in less than 5 years.

I applied successfully after 4 years because I have been married with a Japanese national for many years and answer so many questions in the question forum.
