The building was designed by architect Kenzo Tange from Tange Associates, and it was the last building directly led by him in a huge project. The building is a landmark that symbolizes Odaiba.
It is the largest building in the head office building of a Japanese broadcasting station, and has the largest studio floor area (991.7 km2) as a Japanese private broadcasting station.
The structure consists of an office tower and a media tower connected by three enclosed footbridges. The exterior is cladded with salt-resistant titanium. Special care was taken with the acoustics for the building, including blocking radio waves. The Theatre mall is on the first floor, a rooftop garden is on the 7th floor, and Mezama Sky is on the 24th floor. The Hachitama Spherical Observation Room, located on the 25th floor, provides a view of Tokyo Metropolis. The sphere weighs 1,350 tons and has an off-center of center of mass, which made its installation difficult.
