Providing the systems necessary for data center operations

Hybrid Seismic-movement mitigation system
To reduce the damage to the pillars, beams, and floors that support the building, we deployed two types of vibration control materials, providing resistance anywhere from small to large earthquakes.

The Otemachi district has also been designated by the Tokyo Metropolitan Government as an area with the lowest risk of building collapse and fires during an earthquake and does not require large-scale evacuations. The electricity, gas, and heat infrastructure were also built with an emphasis on safety, achieving high durability and quick disaster recovery.

Security Management

24-hour staffed entrance system
Two-step verification: Visitors to the data center are screened face-to-face by reception staff and must pass a biometric authentication system at entrance gates. By combining a biometric access control system and a 24-hour staffed entrance, our facility achieves a high level of security.
