There are times when I don't get Japan, and then there are times when I *really* don't get Japan. This is one of those times. >_>
Although, I did find that on my travels I ran into a lot of nice people, who made me feel better about being there than the other 90% who wanted to run away screaming when I was crammed in a train or bus with them. I had a lot of fun talking in half-English-half-Japanese to a couple at a laundromat in Hiroshima. Really nice folks. I met some other nice people in Nagoya, and some in Oku-Matsushima when I climbed up Otakamori to see the islands of Matsushima a little better. And I met more nice people when I went hiking in Togakushi in Nagano prefecture.
I do have a theory about the 90% who run screaming into the night. In Japan, they study English in middle school and high school because they have to. Not because they want to. Then the years pass by, and they never use it. All of a sudden, one of those foreigners shows up, and we all know those blasted foreigners all speak English, so they get blathered at in English most likely, and all they want to do is run far away. Over time, it becomes an aversion to anyone who looks like they could speak English.
In Jr. High and High School, I had to take 5-6 years of French, and after that, I just never used it. So right now, if a French person came up to me and started talking to me in French, I would probably get the same feeling in the pit of my stomach that most Japanese get when a foreigner approaches them. You know, that "Oh God, I don't know a word of what he's saying, and I can't remember the words to tell him" feeling.
The other 10% are probably just bored or looking for thrills.
