[QUOTE= On the other hand, drip coffees and iced coffees I find to be pretty high-quality most everywhere including konbinis and Doutor's.[/QUOTE]

Yes, Japan has had high-quality coffee for a long time. When I came back to the States from Japan after living there in the 1970s, I realized how bad (weak and acidic) most commercial grades of American coffee were at the time. I was delighted to find coffee specialty shops like Starbucks and Peet's when I moved to the West Coast a few years later.
