Construction of data centers (DCs) in Japan is set to remain intense beyond 2026, according to a survey conducted by Nikkei BP Co., Ltd. (headquartered in Minato-ku, Tokyo; President and CEO: Tetsuya Iguchi), through its technology-focused media platform, Nikkei XTECH.
Nikkei XTECH conducted the survey between April 23 and May 26, 2026, targeting approximately 80 companies involved in DC operations. Of the 42 companies that provided valid responses, 24 reported plans for 38 new or expanded facilities between 2026 and 2030. Excluding three still under consideration, data center locations break down as follows: 13 in the Tokyo metropolitan area (including Chiba and Saitama prefectures), 9 in the Osaka metropolitan area (including Kyoto Prefecture), and 13 in regions outside Tokyo and Osaka—indicating the gradual start of regional dispersion.
The survey also collected information on planned facilities’ floor area, power reception capacity, cooling performance, liquid cooling systems, and floor load capacity. Five facilities are designed with power reception capacity exceeding 100 megawatts (MW). Facilities supporting liquid cooling—essential for servers equipped with the latest GPUs (graphics processing semiconductors)—account for more than half of all planned projects. There is also a trend toward reinforcing floor load capacity in tandem with liquid cooling adoption.
Nikkei BP’s business magazine Nikkei Business and Nikkei XTECH have jointly launched a special feature analyzing the massive economic ecosystem driven by AI data centers, with detailed survey results published in this feature.
The chart above represents part of the survey findings. For more detailed results, please refer to the Nikkei Business issue dated June 15, 2026, and the Nikkei XTECH article.

FAQ
Why is liquid cooling important for data centers?
Latest GPU servers generate intense heat, making air cooling insufficient. Liquid cooling is efficient and energy-saving, becoming essential.
What are the benefits of decentralizing data centers to regional areas?
Benefits include lower power costs, geographic redundancy, and contributions to regional economic revitalization.
How many data centers have over 100MW of power capacity?
Among the 38 planned facilities, 5 are large-scale centers with over 100MW of power capacity.
