I've been to Japan and I have a few Japanese friends. As a collective, Japanese people have a strong sense of national identity and respect for tradition. The nature of this history is steeped in public formality and the severe dislike of disruption. A common response to an angry individual in Japan is to laugh, perhaps as a way of diffusing the situation, but it can also be seen as an illustration of how rare acts of anger are, to the point that it causes confusion.
Also, the nature of Japanese people can be observed through their language. Japanese is notoriorsly difficult to learn because it is so dramatically different depending on the status of the person you are conversing with. Different situations require different words and sentence patterns...friends, family, bosses, elders. etc all require the speaker to use specific vocabulary words and sentence structures.
These linguistic, cultural and emotional traditions are what, I believe, are responsible for the low crime-rate.
As for the Swiss, they are good bankers, make good cheese and something, something...
