You have to understand that most basic Japanese people are going to have really stereotyped views of America (and other countries) considering how non-diverse their own country is.
From my experience, I've heard the following:
America = Friendly people, tall, blue eyes, outgoing
California = Movie stars and beaches
Texas = Cowboys, ranches, cowboys again
Russia = Beautiful girls, snow, bears
Australia = Loud, rude, blonde/blue eyed
