Tokyo Sky Tree construction work finished

After a two-month delay caused by the Great East Japan Earthquake, construction on the 634-meter Tokyo Sky Tree was completed on Feb. 29. Obayashi Corp., which was in charge of the project in Tokyo's Sumida Ward, plans to hand over the tower to Tobu Tower Sky Tree Co. later in the day. Work on the tower started in July 2008. In March 2010, Tokyo Sky Tree became the tallest tower in Japan when its height exceeded the 333 meters of Tokyo Tower. In March 2011, Tokyo Sky Tree was recognized as the tallest tower in the world, topping the 600-meter Canton Tower in Guangzhou, China. (Asahi)
