I'm convinced that cute and not cute is a confidence thing. Girls with a lot of self worth appear cute even though they aren't physically. They also tend to have healthier diets then most of us. I can't speak about the girls living in Japan but most of the ones I know in the U.S. are really nice to look at and they're sweet too. Unfortunately many of them like to shop and tend to focus on the material. I think that Korean girls work hardest in exercise and being in very good shape. And Chinese girls who aren't married yet are awesome and smart when it comes to attracting men.
Unfortunately you will probably only have luck with Japanese women as Korean and Chinese fathers tend to not like their daughters dating anybody who isn't Korean or Chinese.
