Is there a way to easily visibly differentiate between people of different East Asian backgrounds? For instance, can a person look at the average Japanese woman and know she's Japanese and not Korean?
I know it's possible (generalization, generalization) in white people in some instances - sometimes you can tell a person is a white Brit, or white and Polish, or white and Russian, or white and Swedish.
Anyone have any thoughts?
(For interest's sake, I ask because I'm watching the premiere of The Amazing Race and there's a team of two brothers who are of East Asian descent, and they made a joke about going to "The Motherland", China, though they're not Chinese. I wondered what nationality their family might stem from.)
