Located along Sumida river near Asakusa, the 635 meter-tall (2,083 feet) Tokyo Skytree, designed by Nikken Sekkei, rises in what was once the center of Edo period Tokyo. The tower not only doubles the digital broadcasting capacity in the Kanto region, it is also expected to rejuvenate Tokyo’s historic downtown.

Due to its narrow site, sandwiched by the Kita-jikken river and the Tobu railway, the base of the tower forms an equilateral triangle. As it nears the top, the structure gradually becomes circular in order to house a 360-degree observatory 450 meters (1,476 feet) above the ground.

The tower has a central column within its main structure to withstand shaking from high winds and earthquakes. The column is isolated from the peripheral steel structure and acts as a swinging counterweight to help absorb seismic waves. This type of shinbashira structure can still be seen in five-story Japanese pagodas which have endured Japan’s frequent earthquakes for centuries.

At night, the tower is lit by LED lights, designed by Sirius Lighting Office. The design alternates daily, symbolizing aesthetic ideals of iki and miyabi indigenous to the Edo period locals in the area.
