You can see some difference I think. But China is a very big country and so there are also different type of Chinese.
But the Japanese from the north of Japan also looks different from the southern Japanese.
It is very difficult to say from where you come for us Europeans, unless someone studied this subject.
Very interesting!
I've never really heard of the difference between southern and northern Japanese. Is there really a significant difference? To me they look pretty the same (well, maybe southern ones have darker skin tones, but who knows...)
Here's how I (try to) tell them apart: (J=japan, K=korea, C=china, T=taiwan)
J women: usually have chapatsu, on average maybe a little shorter in status , though I cannot speak with any meaningful stats... never wears any prescription glasses
K women: usually have curly, black, gelled hair
C women: usually wear glasses. Tend to have stronger facial features
T women: look very similar to J women, but maybe a bit taller overall. I find it quite difficult to tell J women from T women at first glance.
J men: usually have longer hair, sometimes with well groomed beard
K men: usually slightly taller than J men. Very often with glasses. Stronger built bodies.
C men: usually shorter hair (shaved hair), no chapatsu
T men: usually longer hair, no beard or mustache
