Step aside Tokyo tower you have just been replaced, the unfinished Tokyo Sky tree has already topped Japan’s old record keeper for tallest structure, Tokyo tower.

Some information on Tokyo Sky Tree:

The Tokyo Sky Tree (東京スカイツリー Tōkyō Sukai Tsurī?) (originally referred to as New Tokyo Tower) is a broadcasting tower under construction in the Narihirabashi/Oshiage area of Sumida ward in Tokyo, Japan. As of 29 March 2010 it is the tallest artificial structure in Japan.[1] When completed, the tower will have a height of 634.00 m (2,080 ft). The present Tokyo Tower (333 m) is not tall enough to give complete digital terrestrial television broadcasting coverage, due to the construction of many nearby high-rise buildings in the central part of the Tokyo Metropolis.

The project is being led by Tobu Railway and a group of six terrestrial broadcasters (headed by public broadcaster NHK). Construction of the tower is scheduled to be completed by December 2011, with public opening from spring 2012. The completed structure will be the highlight of a massive commercial development around Oshiage Station.
