I was stationed there from 1982 to 1985 and then again from 1990 to 1993. I have been to mainland Japan a few times. I even went up Mt. Fuji. When I was visiting Yokota AB, there were clubs outside of the base that were marked "For Japanese Only". I don't know if those still exist. I didn't travel too much on the mainland. I did buy the most expensive glass of Coca-Cola I ever bought while I was there. It was 1984 and an 8-ounce glass (with ice) cost me about $5 (I forget the yen amount). Some town on the way to Tokyo. We were going there to party. After paying so much for just 1 soda, I changed my mind and headed back to the base, along with 1 other guy.
