This looks real nice. Brutus is a bi-weekly Japanese publication about art and culture in Japan. This particular issue here, on sale for $21 at Kurasu (great Japanese site for coffee-related stuff), is all about Japanese coffee shops.
The articles are all in Japanese so if you're a non-Japanese reader/speaker you're gonna be out of luck. However, the photos are great and the maps are helpful if you want to have a caffeine-filled time while in Japan.
