Somewhere, under one of the many gardens in Kadangakure, is a secret doorway completely covered in vines, so not many could tell that there was something there. Past that door is a long corridor, which eventually leads into something that looks like a maze. Only a select few, such as the Niwakage, know the way around this area, and will find a wooden door that had been sealed closed at the end of the maze. Behind that is a small room, where at the far wall, a naginata is mounted. It is very rare that any old shinobi will find this room, since almost all of them would either get lost in the maze and die there, or end up back at the entrance.
