But at stake is whether places like Silicon Valley, Seattle, Salt Lake City, San Francisco or Los Angeles might be forced to shut down after a direct hit and for how long. Right, the building housing Sonys office in Tokyo uses base isolation, as well as another seismic technology known as shock absorbing dampers. The plan of this new addition was first proposed by the tower's new owner OUE group in 2014, who acquired the building in 2013, by this way they can earn an extra of money since the rent rate of the tower is quite low, which problem was the reason for its former owner decided to sell it.
