Asahi is pretty-good beer. It's the Japanese "Budweiser" as far as popularity goes over there.
I've spent some time in Japan on business and drank quite a bit of it. I've seen it here in the US too.
Here's something pretty-cool. While I was in Japan a couple years ago we went to see the Tokyo Giants baseball team play in the Tokyo Dome. The Japanese really love baseball.
One thing I really liked about the experience were the "Asahi Beer Girls". They have these really-cute girls walk up and down the aisles with kegs on their backs. The girls start out at the bottom of each section and bow to the audience. Then the walk up and down the aisles selling beers. Then the girls rotate to the next aisle so every 5-10 minutes or so you have a new girl walking up your aisle. All were super-cute. It's pretty-cool.
