The Gran Tokyo Towers consists of a 200-meter South Tower, a second 200-meter North Tower on a retail base, and a new entrance to Tokyo Station. A simple yet bold strategy was developed to give the development a unique presence. Taut glass facades define the towers’ volume while the angular geometry of the North Tower further emphasizes the different uses of the base and the tower. Various layers of glass define the office and retail components and provide a distinct image on the skyline. The tight site is characterized by elements of traffic circulation, retail, and office uses and access and connections to Tokyo Station. A 234-meter canopy is conceived as a large, flat, textile panel fixed in a straight line at the track edge and supported on steel frames of varying heights and angles spaced at 18-meter intervals. This variation in height and angle gives the canopy its simple yet distinctive profile. The textile panel is suspended from the steel framework allowing the surface of the canopy to be a continuous luminous plane. The structure can be seen through the textile surface and is read like the veins of a leaf.
