Whoa! Way harsh, Elvismen. As one who studied Japanese language and (what you call their "so called ") culture - including living and studying in Tokyo for a year, I can say your assertions are way, way off base. It's not possible to explain why properly in this space, but I'd like to point to a few characteristics of the day to day culture of these "barbaric" people that I have experienced personally:
The Japanese people are incredibly honest and law abiding. Being a bit absent-minded, I have left my briefcase (containing an expensive camera and good quality umbrella) on the subway on more than one occaision. As I'm a New Yorker, I had no expectation of ever seeing my stuff again, however, I took a shot at going to the lost and found and every single time my bag was returned to me with all contents.
In Japan it is possible to leave one's luggage unguarded on train platforms while you go to the kiosk for a soda or newspaper. No one will take it.
Japanese storekeepers generally do not bargain. The price is the price - even if you are a gaijin. If you think you can do better, you are welcome to go elsewhere.
Japanese people do not jaywalk. Even very late at night when there is no traffic in sight they will patiently stand and wait for the light to change.
Japanese restaurants have only one menu. If a gaijin can say or just point to a dish being enjoyed by Japanese people at the next table (for example), the waiter will bring it (anyone familiar with New York's Chinatown can tell you that if you try this the waiter will become deaf, dumb, and blind).
On the famously crowded Tokyo subway, I noticed that there was not one single person - male or female - with dirty, greasy looking hair. Not surprising, since all of these "barbarians" - by strong cultural custom - bath thoroughly every day.
Please contrast the foregoing to any country you wish to name.
To those of you who have spoken of your desire to visit Japan, I encourage you to go and enjoy the modern life and ancient culture of this great country.
