Tokyo Big Sight  , officially known as , is a convention and exhibition center in Tokyo, Japan, and the largest one in the country. Opened in April 1996, the center is located in the Ariake Minami district of on the Tokyo Bay waterfront. Its most iconic feature is the visually distinctive Conference Tower. The name Tokyo Big Sight in Japanese eventually becomes the official name, and it also has become the name of the operator since April 2003. The center was a planned venue for the 2020 Summer Olympics hosting wrestling, fencing and taekwondo events, but cutting of public funds forced the organization committee to choose an alternative location for these events, instead serving as the main broadcasting center and press center for the Games. Located on the shore of Tokyo Bay, about 30 minutes by rail from Tokyo Station, Big Sight is Japan's largest international convention venue. Its most distinctive feature is the unique architecture of its 58 m-high eight-storey Conference Tower. The site utilizes steel frame with reinforced concrete construction, boasting a total floor area of 230,873 m2 which outsizes Makuhari Messe's floor space by half, and of which 35% is indoors. The convention center is divided into three main areas, each with their own restaurants and other supporting facilities: The "East Exhibition Hall", the "West Exhibition Hall" and the "Conference Tower". The architectural element most associated with the Tokyo Big Sight name, the glass and titanium-panelled Conference Tower appears as a set of four inverted pyramids mounted upon large supports. The first floor comprises an 1100-seat reception hall and four conference rooms of varying size. The second floor comprises the "Entrance Plaza" which is the main access area, the glass-roofed "Event Plaza", the "Entrance Hall" which leads to the exhibition halls proper, and the "Exhibition Plaza". There are no floors three through five due to the structure's above-ground stature. Floors six and seven can be directly accessed via escalator from the second-floor Entrance Hall, and comprise the main convention facilities of the Tower. The sixth floor houses ten conference rooms of small to medium size, some of which can be merged into larger spaces by removing intervening partitions.
