It's true that Japan has a very permissive immigration system for high-skill immigrants, because it wants more people like that to help the economy. Japan has a shortage of technical workers, particularly in IT. And I agree, it's done a really good job of providing support for foreigners, better than what I saw in America which is supposedly immigrant-friendly (but not really). However, if this shortage didn't exist and the economy was humming along just fine without any immigration, these lax immigration laws would not be there. Japan used to be very hard to immigrate to prior to this century.
