Unforeseen Simulation Joint

The Unforeseen Simulation Joint (ウソのやルーム), often acronymized as U.S.J., is a training facility located in U.A. High School. It is the primary location of the U.S.J. 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 (セントラル広場): The central area that connects to the simulation rooms as well as the main entrance.
 * Ruins Zone (倒壊ゾーン): Located in the northeast, this zone simulates a destroyed urban environment, with buildings found in precarious conditions.
 * Landslide Zone (土砂ゾーン): Located to the east, this zone simulates sloped terrain with building remains.
 * Mountain Zone (山岳ゾーン): Located to the south, this zone simulates a rocky, mountainous area filled with cliffs.
 * Conflagration Zone (火災ゾーン): Located to the southwest, this zone simulates a urban environment that is constantly on fire.
 * Flood Zone (水難ゾーン): Located to the west, this zone simulates a maritime environment. It contains a ship as well as a waterslide.
 * Downpour Zone (暴風•大雨ゾーン): Located to the northwest, this zone simulates an urban environment that is constantly hit by heavy rainfall and strong winds.

Additionally, the building is equipped with sensors to detect intruders.

History
The Unforeseen 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 U.S.J. 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 Final Exams Arc, where Ochaco Uraraka and Yuga Aoyama faced Thirteen for their practical exam.

Trivia

 * Similar to Gym Gamma, U.S.J.'s initials are a reference to the theme park Universal Studios Japan.
