Unforeseen Simulation Joint

The Unforeseen Simulation Joint (不測のシミュレーションジョイント), often acronymized as U.S.J., is a training facility located in U.A. High. The U.S.J. is  where the U.A. students practice rescue training by simulating all kinds of accidents and disasters. It is the primary location of the Unforeseen Simulation Joint Arc.

Description
The facility consists of a dome-shaped building composed of eight main sections, with six of them emulating a particular environmental factor:


 * Entrance: The entrance to the building, consisting of a large blue gate. Located to the north.
 * Central Plaza: The central area that connects to the simulation rooms as well as the main entrance.
 * Ruins Zone: Located in the northeast, this zone simulates a destroyed urban environment, with building found in precarious conditions.
 * Landslide Zone: Located to the east, this zone simulates slanted terrain.
 * Mountain Zone: Located to the south, this zone simulates a rocky, mountainous area, filled with cliffs.
 * Conflagration Zone: Located to the southwest, this zone simulates a urban environment that is constantly on fire.
 * Flood Zone: Located to the west, this zone simulates a maritime environment. It contains a ship as well as a waterslide.
 * Downpour Zone: Located to the northwest, this zone simulates an urban environment that is constantly hit by heavy rainfall and strong winds.

History
The Unforessen Simulation Joint was idealized by the Pro Hero and teacher Thirteen as a way to train students on how to act through disaster situations.

During the Unforeseen Simulation Joint Arc, the building was invaded by the League of Villains. Through one of its members, Kurogiri, most of the students of Class 1-A were teleported to the various zones located in the facility, where several minor Villains awaited for them. The ambushes were unsuccessful though, as most of the students were capable of fighting back themselves until the arrival of reinforcements.

The building was also used as one of the settings for the End of Term Test Arc, where Ochaco Uraraka and Yuga Aoyama faced the facility's keeper Thirteen himself for their practical exam.
