I'm in Japan right now, and have been for over three months. If you want to taste the worst beer, come here. The arguably best beer here, Asahi, tastes like a Bud Light that's been open for 2 days, except worse. At the end of a workday, I'll find myself going to a store and wanting a beer, and then just giving up because I can't stomach these. What's worse is that they cost on average maybe ¥200 (~$2.50USD) per CAN. Hoegaarden is fairly common, which I actually like, is fairly common in some stores, but runs about 3-4x what I would pay per bottle in the states. If you go to a bar, forget about it. The cheapest beers you'll find are ¥500 for a half pint. It's very hard to find imports. If you manage to find a bar that has specialty microbrew imports (few and far between) you may find yourself paying ¥1500 (almost $20USD) for a glass.
And for the record, Yuengling, Shocktop, and Leinenkugel are just some of the beer makers I like in the states that are in the $7 and under range for a six pack. I think that many European beer drinkers may not like them, because many Americans tend to prefer lagers to ales. I spent two weeks in Austria last year, and missed the flavor of hops very sorely. I really enjoy the variety that can be found in American beer.
There are also many bars and breweries that run great weekly specials on very high quality craft beers, where most nights I can find somewhere where all beer is $2 for a 12oz bottle/draft. I just simply dont drink coors, Budweiser, etc
