Many years ago I coined a phrase — "Frozen Gaijin" — to describe a particular kind of foreigner living in Japan.

A frozen gaijin can be recognized in an instant.

The longer frozen gaijin stay in Japan, the rosier everything in their native country looks to them. Everyone in Australia becomes magnanimously multicultural; everyone in Germany, hardworking and scrupulous; everyone in India, forthright and ambitious. Even British beer starts tasting good to displaced Brits. Frozen gaijin not only feed off the sanguine stereotypes of their nationality, they exalt in them.
