I guess goverment should change the raw if Airbnb becomes more famous in Japan. In Japan, lots of vested interests exits (same as a another countries) so now "minpaku" is discussed in various places - on the Web, goverment, tenants of the apartment, or somewhere.

Sadly, some Japanese unwelcome to foregin traveler. My friend says everyday "Oh, lots of Chinese!" at Akihabara. However, he never complains to white and blacks. It's a real Japanese attitude(not my own).

If more Chinese come to Japan with Airbnb, Japanese will hold a serious discussions on Airbnb.
