If you've never been, you can probably still imagine: Japan is one polite country. A level of politeness like that isn't just "there", it's earned, and it's earned through hard work and diligent instruction.
This is Kuukiyomi. It's a DSiWare game (so you download it to your DSi), and will be out this Spring in Japan for 500 Nintendo Points (or USD$5). As you can see, it teaches you manners. The kind of manners you would have learned from your mother if you'd listened to her instead of playing so many damn video games.
