Just a 7-minute walk from the nearest train station and accessible from multiple train stations, diverse access routes are available even in case of emergency. The Tokyo No. 6 Data Center is built on stable hard ground and is 10 km from Tokyo Bay, and 1.5 km from the closest river.

Tokyo No. 6 also has a large-scale, fully-equipped office building on-site for use during systems monitoring, maintenance and business continuity planning (BCP) operations. 

The Tokyo No. 6 Data Center can reduce seismic shocks to one-fifth their force, preventing adverse affects on your equipment and on our facilities and buildings. Furthermore, all major equipment has redundant configurations. The communications path is connected directly to a secure earthquake-proof cable tunnel.

The Tokyo No. 6 Data Center has achieved the highest level of power usage effectiveness (PUE) of all data centers in Japan. This has been achieved by adopting water-cooled air conditioning with outdoor air cooling system, rotary UPS, which minimizes power loss, and advanced air flow management system.

Japan Tokyo No. 6 Data Center's superior efficiency and space-saving structure enable cost reduction of up to 30 percent per rack. Structural efficiencies enable 50 percent more devices per rack compared to similar data center facilities. This can reduce your operating costs by as much as 50 percent compared to other data centers.
