Gaijin
From WikiJET, the interactive website for the JET Programme
Gaijin (外人?) Literally meaning "outside person", is used to refer to all foreigners in Japan, whether resident or visiting. Some people consider it to be a pejorative term, best rendered as "outsider" or "alien". The more correct and polite term is Gaikokujin (外国人?) or "outside country person", while adding a -san or -sama immediately afterwards increases its level of politeness. In many ways this term has been appropriated by foreigners who often use it to describe themselves and their non-Japanese friends. Its usage is so widespread that it has virtually become a new loanword in the vocabulary of English-speakers in Japan.
