ブラックボックス
Black box spaces are also popular at fringe theater festivals; due to their simple design and equipment they can be used for many performances each day. This simplicity also means that a black box theater can be adapted from other spaces, such as hotel conference rooms. This is common at the Edinburgh Festival Fringe where the larger venues will hire entire buildings and divide each room to be rented out to several theater companies. "The Black Box Theatre" in Oslo, Norway, and the Alvina Krause Studio at Northwestern University are theaters of this type.
