What do you think is the difference between the Japanese sempai - kohai structure with the western juniors - seniors in school or in companies?
If we look at the traditional western arts, how they are taught and structured then there does not seem to be much difference between Western way and Japanese way.
What kind of problems do you see with the sempai - kohai structure?
Well, it's much more rigidly structured and formal than anything you normally see in the US these days. Plus, you tend to exacerbate things when you give them "exotic" titles, and you get people here who are more Japanese than Japanese people in Japan.
The question is - why add an additional cultural layer, and what does it really get you?
