KDDI to Build New Telehouse Data Centers in Tokyo and Osaka

TELEHOUSE invests in expanding a further 20MW of high power density colocation space in Japan

NEW YORK KDDI, the global telecommunications provider, announces today that it will invest $270 million (28 billion yen) investment in the building of two new Telehouse data centers, “TELEHOUSE OSAKA 2,” and “TELEHOUSE TOKYO Tama 3,” scheduled to open in August 2015 and February 2016 respectively. These additional facilities will take the total amount of global TELEHOUSE data center space to approximately 4.0 million square feet, provided by 46 sites across 13 countries/territories and 24 major cities.

Both Osaka and Tokyo facilities will offer high-density colocation services enabling the hosting of heavy load IT infrastructure. The data centers will meet the growing demand for housing private enterprise clouds, along with public cloud service providers, online and media content companies. The facilities are designed to Tier 3+ data center standards in redundancy and uptime, and will be insusceptible to earthquakes by a long-period absorption structure, reflecting the high quality Global TELEHOUSE specifications. In addition, KDDI can provide a combined solution by providing direct access to the KDDI global network along with the data center.

Telehouse Osaka 2, located in the center of Osaka city, will offer 700 racks of tenancy space with up to 30kVA (designed) per rack. The technical and operations room will be situated above second floor avoiding the risk of potential flooding. Osaka 2 can be used as a disaster recovery and back-up site for the Tokyo data centers.

Telehouse Tokyo Tama 3 will be located on the existing Tama data center campus, approximately 18 miles from the Tokyo city center in a highly guarded surrounding. The five story building will offer 1,300 racks of tenancy space with up to 42kVA (designed) power supply to racks, the highest*1 in Japan and 5 times*2 industry average, with a designed PUE 1.31 making it one of the most energy efficient data centers in Japan.


The Telehouse data center expansion reflects the growing demand for data center space in Japan’s metros, and the ability of KDDI to accommodate leading multinationals expanding their portfolios in Japan. By securing its domestic market share in Japan, KDDI continues to be the leader in premium data center facilities.
