Actually, I visit Japan on fairly a regular basis. If there is any sign of public rudeness, I haven't seen it. And while old social norms such as the disregard for the rights of women are still prevalent, they are rarely openly malicious or in-your-face. Train-packing and crowded streets are a way of life on any given business day. However, when there is room and time, people always give each other the right of way and treat each other with a respectable level of courtesy.
I don't have any experience observing Chinese or Korean peoples in their native countries in urban situations (also a very crowded environment). If anyone has any observations, I'd be curious to hear them.
I'm glad I could help someone learn a new word, even if it was in a less-than-comfortable situation!
