Tokyo sky tree tower will be the tallest artificial structure in the world at a height of 634m as tallest building in Japan. The tower will be finished in December 2011, and 70 of the 610 meters are already built. The Sky Tree tower is a little more difficult to get to and the area isn’t as developed as around Tokyo Tower. The Tokyo Sky Tree Construction of the tower is scheduled to be completed by December 2011, with the public opening in spring 2012. Tokyo Sky Tree - the tallest building in Japan - was illuminated to test the lighting.
