When I went to Japan in 1986 one of the things I did was climb Mt. Fuji. I stayed overnight at about 9000 feet in one of the mountain huts that are there for climbers. The people who ran the hut were incredibly nice. I was drenched by cold driving rain and they gave me pants to wear while mine dried over the charcoal pit. They gave me green tea but also took great pleasure in offering this American some instant coffee because they knew Americans were big coffee drinkers. And although I am not wild about instant coffee, I drank THAT coffee with the greatest pleasure. I have pictures of them somewhere with the tray of green tea and instant coffee on it.
