When I visited Japan a few years ago, I was amazed how Japanese people are trying to not disturb you in any way, no one is speaking on the phone in the subway, no one is speaking loud, no one is using their horn in their cars, and then all of the sudden some American guy started screaming "Coming through" from his bicycle on the sidewalk where people were walking in a perfect 3 lines... I think that captures pretty much the two nationalities :D I don't mean to offend anyone, in fact in both of the countries I felt as very rude person just because everyone is smiling, maybe not sincere but still better fake smile then genuine grumpy face :)
