The Tokyo Sky Tree is a broadcast, restaurant, and observation tower, currently under construction in Sumida, Tokyo, Japan. The construction process began in July 2008 and will be finished in the last part of the year 2011, as the official inauguration is planned to take place during the spring of 2012.
As of 2010 it surpassed the well-known Tokyo Tower and became the tallest artificial structure in Japan, with a height of 634.0 metres. It is owned by the Tobu Tower Sky Tree Co., Ltd and the main contractor is, one of the five major Japanese construction companies. The architecture firm is Nikken Sekkei and the developer Tobu Railway Co., Ltd, a Japanese commuter railway company. The total costs of the structure will add up to approximately 40 billion JPY (440 million USD). The lower part of the tower has a structure resembling a “tripod”, yet starting with the higher part, the tower’s structure changes to a more cylindrical form, in order to resist very strong winds and severe weather. Another interesting aspect refers to the actual height of 634 m, which has a specific significance: the figures 6 (mu), 3 (sa), 4 (shi) form the word “Musashi”, which is an old name of the region where the Tokyo Sky Tree is built.
The Tokyo Sky Tree will also function as a communications tower for a large number of several media companies: the most important television broadcasters will be NHK General TV, NHK Educational TV and Nihon TV, while the two FM radio broadcasters will be J-WAVE and NHK Tokyo FM, both broadcasting in Tokyo. In December 2010 began the mounting of transmitter antenna for digital terrestrial television.
After it will be finalized and completed, the Tokyo Sky Tree will be the tallest tower in the entire world, higher than Canton Tower (an observation tower near Chigang Pagoda) and second tallest structure in the world after the Burj Khalifa (in Dubai, United Arab Emirates).
