Apparently he came to Japan in 1977, and obtained citizenship in 1987, about 1 1/2 before her birth. So that makes her an her brother legal citizens.

According to like a million sites, you need to live in Japan for 5+ years, to obtain citizenship. Along with other things of course.

Thank you for answering the question.

That makes her and her brother legal citizens IF she was registered as a Japanese citizen just after she was born.

You obviously want to make this girl out to be a liar, and aren't interested in posts that don't support those ends, but are you sure her father is a "citizen" or a "legal resident"?

No, I don't wanna prove her a liar. I'm just trying to find more information on it, because her and this other girl who claims to live in Yokohama, says everything shes saying is wrong.. so I guess in a way, I'm helping prove her right. I like this girl.

And no, personally I don't know if he was or not, I'm just taking her word for it, but half the things shes said about Japanese culture and Japan are true (from what I've read and been told) as opposed to this other girl.

yeah well, I know it probably wouldn't take that short of amount of time -__- it would probably take me about...20-25+ years just to do it all.

Interesting...thanks for the information :)...even though I probably won't use it for anything, but it's fun to find out some new things!

The rules are simple. The child of a Japanese citizen - if recognized by that parent - is a Japanese citizen regardless of where in the world they are born.

That is the ONLY way to receive Japanese citizenship by birth. Otherwise they are going to need a visa to stay in Japan.

Yup! I was born in Canada but had both a Japanese and Canadian passport. I was tempted to keep using both but I figured the Nikkei visa was good enough. Plus it's legal that way. :)
