Oh, when I was living in Japan they had delicious, quality, cold green tea. I've never found the right kind yet to make it at home. Not the same quality. I think it was a Sencha. And it never had sugar added or anything. It was so great. Sometimes I try to make some at home and I like it but it was not as good as in Japan.
It was funny because they had vending machines everywhere where we could buy cigarrets, beer, tea, coffee, pop, juice. In the summer they would have cold vending machines. The tea would be cold, coffee... And I remember one day waiting while I was doing my laundry. It was fall and I went out to get my green tea that I always got during the summer. Cold green tea. It was HOT! I guess they just flip a switch for the winter and all the beverages go hot. Of course not pop and juice and stuff. That amused me.
