Dublin, Jan. 15, 2026 (GLOBE NEWSWIRE) — The “Japan Data Center Market – Investment Analysis & Growth Opportunities 2026-2031” report has been added to ResearchAndMarkets.com’s offering.
The Japan Data Center Market was valued at USD 12.76 Billion in 2025, and is projected to reach USD 38.91 Billion by 2031, rising at a CAGR of 20.42%.
Japan has about 119 operational colocation data centers. Most colocation data centers are being developed according to Tier III standards. Tokyo is the top data center destination in the country. It continues to be Japan leading hub for data center expansion, marked by a concentrated growth in advanced facilities, hyperscale data centers, and dedicated cloud regions. As of June 2025, there are around 74 existing and 26 upcoming data centers in Tokyo.
After Tokyo and Osaka, the demand for data center investments in locations such as Hokkaido, Kyushu, Nagoya, and Yokohama will increase. These regions offer key advantages, including land availability, government support, and lower land and construction costs, making them attractive destinations for data center investors in the coming years
The trend of liquid cooling in Japanese data centers is growing due to the increasing demand for High-Performance Computing (HPC), AI workloads, and energy efficiency. Liquid cooling is more efficient than air cooling, as liquids can absorb and transfer heat more effectively than air.
In September 2025, Preferred Networks (PFN), Internet Initiative Japan (IIJ), and the Japan Advanced Institute of Science and Technology (JAIST) began pilot testing liquid-cooled high-density AI servers and hybrid-cooled data centers at IIJ’s Matsue Data Center Park (DCP) and JAIST’s Ishikawa campus; the main objective was to develop an ultra-efficient AI computing infrastructure.
JAPAN DATA CENTER MARKET VENDOR LANDSCAPE
- The Japan data center market has the presence of several major data center operators such as AT TOKYO, AirTrunk, Colt Data Centre Services, Digital Edge, Equinix, Fujitsu, Goodman, IDC Frontier, Internet Initiative Japan (IIJ), MC Digital Realty, NTT Communications, STACK Infrastructure, and Telehouse (KDDI). Some of the data center operators have expanded their facilities across the country, with new development initiatives expected to become operational during the forecast period.
- The country accounts for the presence of some of the major cloud operators, such as Amazon Web Services, Alibaba, Google, Microsoft, Oracle, and Tencent Cloud, with dedicated cloud region(s). Their cloud regions are spread across Tokyo and Osaka.
- Several local Japanese companies have formed joint ventures with global companies to invest in cloud computing, AI infrastructure, and sovereign cloud solutions. The goal of these collaborations is to accelerate digital transformation while ensuring data sovereignty, regulatory compliance, and the development of advanced technologies within the country.
- For instance, in October 2025, SoftBank announced a joint venture with Oracle to provide secure, compliant, and scalable sovereign cloud and AI services for organizations across Japan. Using Oracle Alloy, SoftBank will build an advanced cloud infrastructure in the data centers located in eastern and western Japan. All data and systems will be fully managed and operated within the country. The service is slated for launch in the eastern and western Japan data centers in April 2026 and October 2026, respectively.
- The Japan data center market is increasingly prioritizing sustainability, with many operators investing in energy-efficient infrastructure and renewable energy sources. For instance, In October 2025, Microsoft announced the signing of a Power Purchase Agreement (PPA) with Shizen Energy, a Japanese energy firm that offers around 100 MW of solar power in Japan. Additionally, the energy will be supplied from four solar projects located in Kyushu and Chugoku. One of the projects in Kyushu has become operational, while the rest three are currently under construction.
