Tokyo Skytree (東京スカイツリー, Tōkyō Sukaitsurī^?) is a broadcasting, restaurant, and observation tower in Sumida, Tokyo, Japan. It became the tallest structure in Japan in 2010^[2] and reached its full height of 634.0 metres (2,080 ft) in March 2011, making it the tallest tower in the world, displacing the Canton Tower,^[3][4] and the second tallest structure in the world after Burj Khalifa (829.8 m/2,722 ft).^[5]

The tower is the primary television and radio broadcast site for the Kantō region; the older Tokyo Tower no longer gives complete digital terrestrial television broadcasting coverage because it is surrounded by high-rise buildings. Skytree was completed on 29 February 2012, with the tower opening to the public on 22 May 2012.^[6] The tower is the centrepiece of a large commercial development funded by Tobu Railway and a group of six terrestrial broadcasters headed by NHK. Trains stop at the adjacent Tokyo Skytree Station and nearby Oshiage Station, the complex is 7 km (4.3 mi) north-east of Tokyo Station.
