The Xbox 360, to put it mildly, hasn't fared terribly well in Japan thus far. Routinely selling only a couple thousand units every week, the 360 needs a serious kick in the pants if Microsoft hopes to make even a modest dent in the Japanese market. For this reason, it's heartening to see an Xbox 360 game claw its way to the top of the Amazon Japan bestseller list. The game in question is the Namco Bandai RPG Eternal Sonata, known as Trusty Bell in Japan.
