[5] 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.

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.

Scattered around the Tower's vicinity are public art pieces, most of which are works by international artists such as Claes Oldenburg and his wife Coosje Van Bruggen, Michael Craig-Martin and Lee U-Fan.

The glass-roofed galleria is equipped with moving walkways for easier movement, food outlets, escalators, electronic signboards and a host of other relevant facilities.

Unlike its West counterpart, the East Exhibition Hall is not located next to the main Conference Tower area.

Contracted by the Tokyo Metropolitan Government's Bureau of Finance, the construction of the entire site was handled by eight contractors in total, among them companies such as the Hazama and Shimizu Corporations.

Then Governor of Tokyo Shunichi Suzuki was present at the 1994 lifting-up ceremony on June 30, which initiated the raising the Tower's 6,500 short tons (5,900 t) main structure above ground,[4] a process which took three days to complete using a computer-guided system that precisely jacked the structure up into place.
