What is "gaijins"

Usage examples of "gaijins".

At two o'clock in the morning, the streets still swarming with young Japanese in American sports cars, girls sitting on the back of convertibles, gangsters and whores emerging from nightclubs, moving on to the next place, shirtless gaijins howling at the moon from upstairs whorehouses, I staggered down dark back streets, hit some more bars and, finding myself incongruously hungry again, and wanting to soak up some of the sea of alcohol in my stomach, committed the ultimate in Tokyo faux pas-I ate a McDonald's hamburger while I walked.
