Yesterday I picked up a copy of The Japan Beer Times at a shop in Tokyo station. It's bilingual, so if you are interested in Japan's craft beer scene then you might find it useful. The web version is here:

On a side note, anyone interested in the craft brew scene in Tokyo/Yokohama should check out this blog:

I can personally recommend Popeye's (Ryogoku) and Thrashzone (Yokohama).

「美味しいビールが飲める店、どこか知ってる？」 is a useful sentence.
