Vibration-control engineering
Construnted using the most advanced quakeproofing technology in Japan, with a combination of CFTs and the latest vibration control devices (viscous dampers). These divices minimize the damage sustained by the main structure of the building in the event of an earthquake, even one of a magnitude comparable to that of the Ganshin Earthquake.

CFTs
CFTs (concrete-filled tubes) are steel tubes filled with high-strength concrete, marked by their excellent durability and anti-deformation properties. These thin tubes provide a structure that is both earthquake- and fure-resistant.

Viscous dampers
Viscous dampers are shock absorbers comprised of a piston and a cylinder containing a viscous fluid. Shaking of the building due to earthquake or high winds is converted to relative motion of the cylinder and pistion, using the ressistance of the viscous medium to absorb the energy of vibration.
