Japan’s NHK and other broadcasters have proposed a new tower in Sumida, Tokyo… which if completed, would be the world’s tallest free-standing tower (611m) and the tallest man-made structure in Japan.
The new tower is officially named Tokyo Sky Tree (東京スカイツリー, Tōkyō Sukai Tsurii) following a public voting by Tokyo residents. The tower is currently scheduled for completion in 2011.
