I'm an American living in Japan (about 12 years now). Most of the stuff he's talking about is totally true. But, like some other commenters have been saying, I feel like: you figure that stuff out after a couple years and make peace with it (or not). There are many good and bad things about Japan. And it's different if you're a foreigner in Japan, yes. And it depends on where you're from and what color your skin is, etc.

My only question is why did it take him 10 years to "get fed up" with it? Most people who leave do so after a year or so. Most people who stay longer than a couple years tend to stay for a very long time.
