LINK. The world's second-tallest structure opened to the public on Tuesday. The Tokyo Sky Tree is now the world's tallest broadcasting tower. It is expected to draw in 32 million visitors a year, more than Tokyo Disneyland. Featuring two observation decks and an adjacent shopping arcade which includes a planetarium and an aquarium, it stands 2,080-feet high on the eastern side of city, away from the glitzy Shibuya and the Ginza districts. Sky Tree overlooks Sumida and Arakawa rivers, the symbols of Old Tokyo area, and on a clear day provides a panoramic view beyond the capital including Mount Fuji. As its name suggests, the tower employs branch-like joints made of high-strength steel tubes and is anchored with triangular, walled spikes 330 feet underground like a root of a tree to withstand strong earthquake and typhoons.
