Nippon Telegraph and Telephone: NTT builds a new data center in the Kansai region

NTT Corporation (NTT; Headquarters: Chiyoda-ku, Tokyo; Chief Executive Officer: Akira Shimada) announces an investment of approximately 40 billion yen through NTT Global Data Centers Corporation (NTT GDC; Headquarters: Chiyoda -ku, Tokyo; CEO: Yasuo Suzuki) to build a new “Keihanna Data Center” (provisional name; hereinafter referred to as “the Data Center”) in Kyoto Prefecture, and NTT Communications Corporation (NTT Com; registered office: Chiyoda-ku, Tokyo; President and CEO: Toru Maruoka) expects to begin providing services in the second half of fiscal 2025.

The Kansai region centered on Osaka Prefecture is a rapidly growing market for data center companies, second only to the Tokyo metropolitan area, which is the largest in the Asia-Pacific region. As business DX (digital transformation) continues to advance, there is strong demand from local, national and global businesses to provide a wide range of services. These services include expanding bases for IoT verification and software development, as well as establishing secondary centers and disaster recovery centers to promote sustainable management. In addition, hyperscalers, which are developing large-scale cloud business globally, demand the expansion of service bases in the Kansai region to expand their business by targeting customers in central and western Japan. . Due to these increasing demands, the market size in the Kansai region is expected to reach approximately 500MW of power capacity by 2026. To meet these demands, NTT GDC will establish the data center in Kyoto Prefecture and NTT Com will provide the data center. associated services.

NTT Group is working on IOWN (Innovative Optical and Wireless Network), a network and information processing infrastructure comprising terminals capable of providing high-speed, high-capacity communications and vast computing resources. While accelerating this research, NTT and NTT Com will use the data center as a hub to provide commercial services based on IOWN in the future.

Against the backdrop of such a strong market in the Kansai region, NTT Group will increase its investment in the data center industry, aiming for the rapid realization of IOWN while continuing to meet market demands.

Data Center Overview

1) The location of the site

The data center is being constructed in Soraku-gun, Kyoto Prefecture, on flat land located approximately 94m above sea level with low disaster risk. The data center is also accessible from the cities of Osaka, Kyoto and Nara within an hour by car.

2) The building

The building is a seismically isolated four-story structure that will stably supply a total of 30 MW for IT load (starting at 6 MW and gradually expanding) to a 10,900 m² server room (equivalent to 4,800 racks). In addition to providing redundant power supply, air conditioning and communication equipment meeting international Tier III standards for data centers, disaster countermeasures and enhanced security, long-lasting and safe services thanks to the improvement of energy-efficient equipment.

3) The network

In addition to providing highly reliable communication services through low-latency, high-capacity backbone lines and redundant access lines, flexible connectivity enabling connections between different clouds and customer bases will also be available. Additionally, the data center offers carrier-neutral connectivity that allows customers to select other companies’ networks and ISPs based on their needs.

4) Supply of renewable energy

To reduce greenhouse gas emissions, which cause global warming, the data center will achieve net zero CO2 emissions by using renewable energy at the request of customers.

5) Towards the realization of IOWN

The data center will be built next to NTT Group’s research and development facilities to further promote IOWN-related research. NTT will conduct demonstration experiments for commercialization with collaborative companies and other organizations. In the future, NTT will make energy efficiency 100 times*1 from the current rate, multiply the carrying capacity by 125*2and reduce the end-to-end delay to 1/200*3 of the current pace by realizing an All-photonic network. Following the example of NTT Com’s “Tokyo 11 Data Center”, which is already undertaking similar initiatives, the Data Center will also expand the IOWN test environment, allowing NTT’s research resources to be used more efficiently and accelerating the practical application of research results.
