The training arena is nothing more than an open, grassy field behind the barracks. Boulders are strewn about the field, creating obstacles and hiding places. The field is also pockmarked with small craters, accidentally created from poorly controlled kido training.
The field is protected around its perimeter by multiple layers of strong barrier-type kido, to prevent unauthorized use and to contain any out-of-control kido that could potentially do major damage to the surrounding area.
