Immigration is painfully unlikely due to cultural issues. It's oft suggested by non Japanese people looking at the problem but at least from what I can see, the majority of the Japanese voting public don't want immigration. There's reasons if you want a fun read. Particularly interesting is the history of people of Korean decent who are native Japanese residents for a generation or two.
> the majority of the Japanese voting public don't want immigration The vast majority of the American public don't want it either, but businesses do, so it happens anyway.
I've lived in America for just 3 years, yet have never felt unwelcome. In fact, most Americans I meet are very curious to know about my origins and the country I grew up in. But maybe that's because I live in a very liberal city (Austin) and can communicate well in English.
I've lived in Korea for some time and unfortunately never learned much Korean to be considered fluent. So I did have a hard time. Its also a very homogenous country so I guess it makes sense why they're so exclusive; I think its the same case in Japan too.
Historically, Koreans and Japanese ( and to an extent, the Chinese) have placed an almost absurd weight on purity of their race. I don't know the situation for other places.
