The training facility is a circular building that isn't tall, but quite broad. Inside the facility gives a comfortable atmosphere for those who enter, which are mostly Imperial shinobi who have signed and requested a field to train in.
An idea originating from Amegakure, the facility sports at first sight only bland looking fields. Teams of chuunin who have specialised in certain elements and techniques work together as a team to form the field into something that a signed up team has requested. This allows for training in many more surroundings and scenarios.
