Japan Tops off the Tokyo Sky Tree—World's Tallest Comm Tower

I used to think San Francisco's 977-foot Sutro Tower was impossibly tall. But it's just a stub compared to the Sky Tree, Japan's 2,080-foot tall communications centerpiece and the second tallest building on the planet, dwarfed only by the Burj Khalifa.

The Sky Tree is located in Sumida, Tokyo and cost $806 million to complete, which includes a two-month delay on account of the devastating earthquake and tsunami. Over half a million workers aided in its construction which concluded Wednesday.


The tower includes numerous communications arrays necessary because the current 1093-foot Tokyo Tower is no longer tall enough to bounce video and radio transmissions past the surrounding high-rises. They'll also help improve digital signal coverage as Japan quit all analog broadcasting in July of last year. The tower will also include office space, broadcasting facilities—it's home to seven Japanese broadcasters spearheaded by NHK—dining and shopping areas areas, and observation decks as well. These decks will rise from the tower's 1,312-foot-wide base, at heights of 350 and 450 meters, respectively. They'll open to the public on May 22, 2012.
