Tokyo returns to the world's architectural stage with this massive broadcasting tower, scheduled for completion in 2011. It will rise above what was the Tobu Railway Company's rail yard in Sumida Ward. Discussions about a new broadcast tower have been ongoing for years, but it wasn't until 2006 that Tokyo's major broadcasting companies and the national broadcaster, NHK, agreed on this plan.

This tower will carry antennae for Tokyo radio and television stations, which are currently at the top of Tokyo Tower. However, Tokyo Tower is quickly being surrounded by massive skyscrapers which cause mutltipath and other problems with radio signals. The new tower will allow the broadcasters to locate their transmitters at a higher point to alleviate the congestion. As part of the move to the new tower, the broadcasters will abandon their analog facilities and move to pure digital operation.

Unlike the current Tokyo Tower, the base of Tokyo Sky Tree will be more than an expanse of asphalt with some scraggly gardens and minor amusement facilities. It is envisioned as an entire urban working, shopping, transportation, and community center, right beneath the tower, helping better utilize the available space.

Of course, the real star of the show is the tower, itself. Rising from a triangular-shaped lobby with a large arch on each side, the core of the building will be surrounded by a lattice work of structural steel. As the building rises, the core changes to a circular shape by the time it reaches the first observation level. The second level is 330 feet higher, but smaller. This is topped by the continuing steel cone and eventually a master television antenna.

Notes
  • Architect: Tadao Ando
  • This building is designed to be extra earthquake-resistant because it will serve as a vital communications relay during disasters.
Did You Know?
  • A triangular-shaped lobby was chosen because it has three sides -- the smallest number possible for a self-supporting structure. They also symbolize the confluence of the Sumida River, the Ara River, and the bustle of human traffic.

  Tadao Ando and any great architect is to be praised for taking a landmark like the former Tokyo Tower (Original architect Tachu Naito) to greater heights and towards a greater future!The Best is yet to come!!We welcome July 2011.

  I have resided in Sumida ward for over 18 years. Tokyo Sky Tower is a wlcome addition adding a contrast to the old town of Asakusa, just across the Sumida River. They have extended the height by 24 meters to beat the height of a tower now under construction in China. I worked on a dam as a young man that was not even 500 feet tall. Gotta respect those construction workers on this job, the Tokyo Sky tree!

  Excellent. At last something new for Godzilla to destroy.

  Trying to replace the Tokyo Tower with a taller structure is like trying to replace the Empire State or Chrysler Buildings in New York. They achieved icon status not just because off their size, but also because of their design, despite "new", taller structures. This new tower looks like an erector set on steroids, and doesn't say "TOKYO, JAPAN" to me--it could be built anywhere.

  While I do enjoy the futuristic heading and the forethought put into both the design and uses, I cannot say that I will not miss the classical, almost symbolic, figure that is the Tokyo Tower today.
