Japan has amazed the world in 2012 with the impressive Tokyo Skytree, locating at the urban area of Sumida-Ward (part of the mainland in Tokyo, Japan). It superseded the position of China’s Canton Tower as the tallest freestanding tower in the world with the height of 634m. This broadcasting tower’s construction cost is USD 806 million owns by Tobu Railway Co., Ltd. and Tobu Tower Sky Tree Co., Ltd., which are part of the Tobu Group that involves in the development of railway, theme parks and hotels. Nikken Sekkei Firm consists of excellent architects, engineers and planners to conduct this project while the main contractor is Obayashi Group. Nikken Sekkei Firm has involved in many constructions of the prominent buildings in Japan such as Tokyo Tower.
The main function of Tokyo Skytree is replacing Tokyo Tower to transmit the digital terrestrial broadcasts in Kanto region (the largest island of Japan), as the latter is no longer be able to perform well due to the increase of high-rise building around it. Besides the restaurant and the observation decks at the top, it has also shopping centre with aquarium at the base. Its role as the tourist attraction has successfully brought in about 25 million tourists annually. Also, It transmits information for recovery during disaster period.

The changes in shape also demonstrate the “warp” and “camber” which are traditional shapes in Japanese culture. The colour design is ‘skytree white’, a mixture of indigo blue and white results in a pale blue glow of the
