Asians (ie. yellow people) in Asia treat foreigners like crap. They don't have the same view of the western world that we have. They don't idolize the west like some of you think. They are extremely conservative even if they don't look like it. They've never had prolonged exposure to other ethnicities, so you shouldn't expect them to like westerners.

Yellow countries aren't nearly as multicultured as the western countries. In fact, I'm willing to bet that over 99% of people in Asia are yellow people. You can argue that tourists go to Japan and whatnot all the time, but the relatively small number of tourists barely makes a dent in the demography. They're still pretty much interacting with other yellow people and living yellow culture 24 hours a day. When you live in a society that has an overwhelming majority of one ethnicity and culture, then it's only natural that you'd be highly conservative.

Appearance is the easiest way to distinct westerners. Even though I'm not Japanese, people probably wouldn't glance at me twice because I'm yellow. I don't stand out in a crowd of other yellow people as opposed to white, brown or black people. When they find out that I'm actually not Japanese, they'd probably still treat me worse than they do real Japanese folks.
