539m done, 95m to go ! The Tokyo Sky Tree (東京スカイツリ) is a broadcasting, restaurant and observation tower under construction in Sumida, Tokyo, Japan. It is the tallest artificial structure in Japan since 2010. When completed, the tower will have a height of 634.0 metres (2,080 ft). The completed structure will be the highlight of a massive commercial development as it is located equidistant from Narihirabashi Station and Oshiage Station. One of Tokyo Sky Tree’s main purposes is as a television and radio broadcasting tower. Tokyo’s current broadcasting tower, Tokyo Tower, is at 333 m (1,093 ft), no longer tall enough to give complete digital terrestrial television broadcasting coverage as it is surrounded by many high-rise buildings. When completed, the Tokyo Sky Tree will be the tallest tower in the world beating Canton Tower, the tallest structure on an island beating Taipei 101 and the second tallest structure in the world after the Burj Khalifa – wikipedia
