I finally stopped by Junkudo near Loft in Umeda (Osaka). This is a huge bookstore and has the biggest selection of English books I have seen in Japan. For example, my books in English are really hard (impossible?) to find in Japan (Japanese versions are easy). But Junkudo had my first two books and the bento box (but not the naked book yet). An impressive store for sure, but they still do not have the titles that an Amazon has (or their low prices). Still, I like bookstores and even bought a couple of books there.
