It really is exciting to walk into a bookstore in Japan and see so much manga!  There's a lot of good manga in Japan but it can be difficult to find because there's SO much there!  You need to spend ages going through titles to find something that is really a powerful combination of story and art.  I guess this is another disappointing reality that J has to face now that he's in Osaka.  Everything isn't perfect in Japan.  I'm not sure how much Japanese J can read so maybe he's just judging the manga by the artistic storytelling.  Friends would tell me about good manga to read and it would save me time at the bookstores.  Did you have a good experience the first time you went to buy manga in Japan?
