The purpose of the Doujou is to train pets, to provide a place to leave pets you aren't using, and also to train their potential. You do this by talking to the instructer[]. The Doujou can hold a maximum of 150 pets. Besides the 6 small medals (click on the map on the right for location), there is no real treasure here. You can pickpocket the koma-inu near the front, but not the foreign gate (which is precious) in the upper right. It uses track number 61 for it's music (mcJapan).
