English Books!!! (and about the only place to get them too!)
Kinokuniya is the best bookstore in Japan to buy English books at. In fact, within Osaka, its probably the only place to buy english books. It has a good section of Novels and then Japan travel and language books. Great for the foriegner working and living in Japan. Its a busy place...but pretty much everywhere in Umeda station is. Of course, books that you could get at home will be more expensive here, but its about the only option you will have to buy things in English.
