Peter Hessler gives another account of the way the Chinese behave around Westerners in River Town: Two Years on the Yangtze.

Most of the attention was innocent curiosity, but it made the embarrassment of my bad Chinese all the worse - I'd try to communicate with the owner, and people would laugh and talk among themselves, and in my nervousness I would speak even worse Mandarin. When I walked down the street, people constantly turned and shouted at me. Often they screamed waiguoren or laowai, both of which simply meant "foreigner". Again, these phrases often weren't intentionally insulting, but intentions mattered less and less with every day that these words were screamed at me. Another favorite was "hello", a meaningless, mocking version of the word that was strung out into a long "hah-loooo!" This word was so closely associated with foreigners that sometimes the people used it instead of waiguoren - they'd say, "Look, here come two hellos!" And often in Fuling they shouted other less innocent terms - yangguizi, or "foreign devil"; da bizi, "big nose" - although it wasn't until later that I understood what these phrases meant.

The stresses piled up every time I went into town: the confusion and embarrassment of the language, the shouts and stares, the mocking calls. It was even worse for Adam, who was tall and blond; at least I had the advantage of being darked-haired and only slightly bigger than the locals.
Even though Japan and rural Sichuan are polar extremes when it comes to economic development and exposure to the outside world, the spontaneous reaction prompted by the sight of a Westerner is remarkably similar, be it the need to stare and openly call them by a term meaning "outsider", or the questions about the local food and the use of chopsticks. This is definitely not the way Westerners comport themselves towards Asian visitors, even in rural areas.

Though a Gaijin won't draw a crowd in central Tokyo, he or she might in the suburbs or in the countryside (especially children and teenagers). It would be worth investigating if there isn't a innate (i.e. genetic) predisposition among East Asians to react in that way to people who look distinctly different. I have noticed the same phenomenon in Korea and Thailand, for instance, but it was less obvious in Indonesia, Malaysia, the Philippines or Cambodia (all of which are more genetically distant from the Han Chinese), where Westerners are met with more indifference, or at least not very differently from Latin America or the Middle East.
