Attack on Titan takes place in Germany.
But yes I have noticed how they definitely have an affinity for white looking features. Please do not buy into the "they are not supposed to be white" or the "they just draw them that way" or "they are supposed to be aliens" crowd. Bullshyt. They know the characters look white. East Asians in general favor blonde hair, blue eyes, double eyelids, round skulls and pale skin. You will also find that many Asians have an obsession with Germany for that very reason. If you travel to Korea or Japan, bleaching creams are everywhere. Do not fall for the bullshyt excuses anime obsessed brehs will try to feed you. Double eyelid surgery is popular over there for a reason. Skull reshaping surgery is popular over there for a reason. Nose surgery to make their noses look sharper is popular over there for a reason.
I love anime but that shyt is blatant as hell and if you are around Asians like I am (due to work) then you would already know they want to look white while still calling themselves Asian. Backwards shyt really. There is a reason so many of their women chase after white men and dream of having hapa children. Don't be fooled into thinking that this would not also affect their art. For any idiot that mentions DBZ as an attempt to downplay the white looking claims, please explain why Krillin and Chinese characters are drawn to look the way they do? You already know the answer. Hell a lot of Japanese consider themselves the "whites of Asia.' That should tell you all you need to know about this subject. They take pride in their culture, great pride, but not so much in their features.
With that said, not all anime artists are obsessed with white features. There are a few who draw their characters to look like their people and there are also a few characters that are drawn to look like others races as well.
