The Tokyo Sky Tree will appear in the Narihirabashi/Oshiage area of Sumida Ward. Boasting a height of about 634m, the tower will be one of the world's tallest. In July 2011, the current analog broadcasting will end and a complete transition made to digital broadcasting.
Five commercial stations and NHK took this as a turning point to advance preparations towards digital broadcasting from a TV tower with a height of around 634m and decided on the Sumida/Taito area as the site for construction of the tower. In addition, for "one-segment broadcasting (one-seg)," a digital broadcasting service for mobile devices that was launched in April 2006, it is ideal to have transmissions from a height that is not very vulnerable to the forest of super high-rise buildings that stand at heights of around 200m in downtown Tokyo. Expectations are also on the tower to serve the role of a tower equipped with disaster prevention features.
Located about 1km east of Asakusa - a town filled with the atmosphere of a shitamachi (the traditional name for the area of Tokyo that extends from Taito, Chiyoda and Chuo Wards east of the Sumida River where many merchants, craftsmen, etc. reside) - and about 2km northeast of Ryogoku - a town famous for sumo wrestling. The new tower stands in a major traditional international tourism zone of Japan. Grand opening: spring 2012
