In America, if one is a visible minority, even if one is born/raised in America the following conversation might happen:
A: Where are you from?
B: New York
A: No, where are you from from?
In this situation, "from from" is supposed to indicate they want to know what your ethnic origin is/where you and/or your parents originally immigrated from. For some more context, you can see the first twenty seconds of this video or this article.
I was wondering how one might replicate that conversation with that nuance in Japanese (replacing New York with Tokyo and assuming that B is a visible minority in Japan), but I'm struggling with the last line.
Any ideas? Creative suggestions that don't exactly translate the dialogue, but capture the awkwardness of the situation for person B are very welcome. Or maybe this concept is just too difficult to explain simply?
EDIT: My purpose in asking this question isn't to actually ask someone this question. It's to try to, via a translated dialogue, explain this situation to someone in Japanese. And hopefully without having to go on a long winded explanation of American culture.
