This technology is called the “added mass control mechanism.” When a building shakes during an earthquake, the overall shaking is countervailed and minimized by a device that shakes out of sync within the building. At the center of the tower stands a 375-meter steel-reinforced cylinder, fully 8 meters across and weighing 11,000 metric tons. At 2,080 feet (634 m) the tower stands nearly twice as Japan's previous tallest frame, the 1,091-ft (333-m) Tokyo Tower transmitter. They are known to be extremely resilient to earthquakes. Using wall-shaped piles increases the useful frictional resistance with the ground. Co,.Ltd, “Since the natural environment of Japan places severe demands on high-rise structures, the investigation of ways to withstand earthquakes has a long history,” comments Konishi. The shinbashira moves independently of the tower, counterbalancing and suppressing swaying motions during an earthquake,” explains Atsuo Konishi, the structural designer of Tokyo Skytree working for Nikken Sekkei Ltd, which designed the tower. The Tokyo Skytree was inaugurated on May 22, 2012, a few months late due to the 2011 earthquake. Of course, such resilience is nothing without the proper foundation, and its the Sky Tree's foundation that gives the buildings its name. Nikken Sekkei, the design practice behind both buildings, effectively doubled its personal best in the construction of the Sky Tree, and in doing so employed the latest technology, not to mention the expertise of "more than 100 architects, engineers and planners", to build the capital city's striking quake-resistant giant - a super-tower its designers claim offers "better safety" than any other.
