At 634 meters Tokyo Skytree is Japan’s tallest building and was, at the time of completion in 2012, the second tallest structure in the world after the Burj Khalifa in Dubai (830m). The tower has two observation decks at 350m and 450m. The significance of the 634 meters is a play on the word mu-sa-shi (6-3-4), a former province of Japan that enclosed the present day Tokyo Metropolis as well as some areas of Saitama and Kanagawa.
