School District 3 (第三学区 Dai San Gakku?) is the northernmost district in Academy City. It is bordered by the Saitama Prefecture to the north, School District 14 to the east, School District 4 and 16 to the south, and School District 20 to the west.
Its primary focus is for accommodating authorized outsiders, which includes hotels and restaurants.
It is the school district that has accommodations for its authorized outsiders. There, the district contains a number of international exhibition halls, which promotes state-of-the-art technology from Academy City to its guests. As such, there were always multiple events being held in District 3, such as motor shows, robot shows, and specifically, the Interceptor Show. Technology that the Board of Directors had deemed of an acceptable level to be used outside the city was on display and the outside company that gave the best deal was chosen (Academy City did not "look for" them, they merely "chose"), and that company would pay them vast amounts for that tech.
A direct railroad line leading from School District 23 to School District 3, allows foreigners to quickly access the luxurious hotels and facilities of the district that were the highest in all of Academy City.
