Not necessarily, samurai8...
Yes, only a few people have told me that it is difficult to apply for Japanese Citizenship but I think the best of all, as long as you contribute to their society and just at least stay there for 5-10 years approx. then you'll be able to obtain one. I think us foreigners hardly can get into it, because even if we live there long enough to experience Japan, probably most of the time, foreigners still seem to not get the what they expect of us...

But hopefully, since I'm still a teenage, willing to live there in future, I just hope that it'll somewhat change in the future!

But I have heard that there is a proposal to change some of the regulations in Japan of migration, as being proposed by the Liberal Party of the Japanese government.
