iBooks 3.1 brings paid content to iBookstore in Japan

Version 3.1 of iBooks is out today and while it might not bring much in the way of new features for Western users, it's a pretty big deal for book lovers located in Japan. That's because the latest update introduces paid content on the order of hundred of thousands of books -- encompassing novels, manga and more -- something that the country's iBookstore has been without up until this point. Before now, iOS users in Japan have needed to be content with public domain e-books.

In addition to the paid content rollout, the 3.1 update also introduces some improvements when reading Asian language books.
