The Official Pocket Monsters Diamond and Pearl Website has been given a face lift. Not much has changed content wise, but the site does have a higher resolution version of the newest promo poster.
The website contains, news, character bios, previews and summaries of the upcoming Diamond and Pearl episodes. The website is in Japanese.
