The tower took three years and 10 months to build. Websites: Tokyo Sky Tree official site Wikipedia Wikipedia Construction of Tokyo SkyTree and March 2011 EarthquakeĬonstruction of Tokyo Skytree began in in 2008. The easiest way to get in is to join a tour group in which the tickets have been worled out. Those that try to do it on their own have waited for six hours and ended up empty handed. A total 6.34 million visited the tower the first year it opened and 50 million visited the shopping mall and area around it. There is the glass-walled observatory deck at a height of 450 meters that offer a panoramic view of the city. Tokyo SkyTree was recognized as the world’s tallest free-standing tower by the Guinness Book of World Records in 2012. The tower is the primary television and radio broadcast site for the Kantō region and tower is the centrepiece of a large commercial development funded by Tobu Railway (which owns the complex). It resembles a 5-storey pagoda from historical Japan. Built by Tobu Railway, Tokyo SkyTree cost around ¥50 billion (US$400 million). The tower is significantly higher than the 553-meter-high CN Tower in Toronto, which for a long time was the world's tallest freestanding structure. Originally called New Tokyo Tower, Tokyo SkyTree is radio TV transmitter tower used by NHK and five commercial televison stations. Opened to public in May 2012, it surpassed the 333 meter height of Tokyo Tower and became the highest structure in Japan in March 2009. It claimed that title over the 600-meter-high Canton Tower in Guangzhou when it reached the 601 meter mark in March 2010, two years and seven months after construction began. The marine construction technique is a combination of triangles with diagonal, lateral and principal elements interlinked through branch joints.Tokyo Skytree under constructionTokyo SkyTree (Oshiage Station, served by four rail lines including Keisei Oshiage Line and Tobu Skytree Line, seven kilometers northeast of Tokyo Station) is the world's highest free-standing tower at 634 meters (2,080 feet) tall. Truss elements – tripod truss, lateral joint truss and ring truss – are used for the entire structure. The key elements have been built with double standard strength steel channels. The main structure of the tower is made of steel tube frames. Steel tubes at the base measure 2.3m of diameter and have 10cm of thickness. The walled piles are interconnected radially. Large piles of the Sky Tree tower are built in the shape of nodular-walls and integrated into the ground to give more frictional resistance. Lines from three apexes of the triangles converge about 50m above grade along the 600m height. Triangular shapes reduce the structural steel required for construction. The tower rises on three legs from an equilateral triangular footprint of side 68m. The structure represents state-of-the-art Japanese engineering. Structure of the tallest free-standing building in the world The second observation deck and air corridor are at a height of 450m. It accommodates a restaurant, café and shops. The first observatory is located at 350m above the ground. The observatories have a round shape to offer panoramic views of the river and the city. The silhouette of the tower differs when it is seen from different angles. The curves also reflect the blade of a samurai sword and other traditional Japanese architectural shapes. The building, which is situated on the corner of Omotesando and Kyu Shibuya River Promenade (known as Cat Street) a well-known area for designer shops, is a multi-purpose retail complex including big name shops and designers such as Chanel, Bulgari, MoMA Design Store (first outside the US) and Maison Martin Margiela.Ĭamber structure is commonly used in columns of Heian and Nara era temples architecture. The 8,970m² Gyre building opened in Tokyo, Omotesando-Harajuku area on 2 November 2007 (building started in June 2006).
