KVH Tokyo Data Center 2 (TDC2)

One of the world's most advanced and secure data centers

KVH Tokyo Data Center 2 is one of the most advanced and secure data centers in the world. It has the highest level of seismic isolation of any data center in Japan and is in an ideal geographic location – being within easy access of central Tokyo and close to the major landing stations serving Tokyo, while also being 20km from the coast. In addition, we have expansion capacity for another three data centers on the same site. For these reasons, KVH TDC2 is rapidly becoming a major hub for the financial services and cloud services industries in Japan. KVH TDC2 offers 4,000m² of compute space within Tier III+ architecture (upgradeable to Tier IV upon customer request).
