It's not really suprising to me. Japan has a very western influenced culture now, so the archetype for an attractive woman is very similar. In fact this generally accepted archetype is pretty much the same around the worls with the exception of a few back aswards countries in the mid east.

On the apparent "ethnicity" of anime characters. It's not that easy to maintain any semblence of ethnic origin in the generally accepted anime form. The minor nuances that seperate western skin tone and bone structure from their eastern counterparts can't easily be portrayed well in anime style art.

I'd say the most Japanese looking characters I've seen are Satoshi Kon's work, although he goes more for of an artistic rendering of real people, charactures if you will.
