Tokyo Skytree and the Tokyo Metropolitan Government buildings are among the nearly 1,000 structures nationwide that use earthquake shock absorbers produced by scandal-hit KYB Corp., which admitted Tuesday to fabricating data related to product quality for more than a decade.
It's unclear what degree of risk the data fabrication could pose to the structural safety of the properties.
The operator of Tokyo Skytree said Wednesday it uses a system by KYB for absorption and control during a seismic event and is now checking whether more devices manufactured by the company are used at the 634-meter-tall tower in the capital's Sumida Ward.
