Japan’s data center construction market is forecast to expand at a CAGR of 7.40% from 2026 to 2033, with the market size in 2025 estimated at approximately ¥1.2 trillion to ¥1.5 trillion.
Japan’s domestic data center construction market is expected to grow against a backdrop of government deregulation and policies promoting digitalisation. The market size in 2025 is estimated at approximately ¥1.2 trillion to ¥1.5 trillion, and is expected to expand at a CAGR of 7.40% from 2026 to 2033. This includes support such as tax incentives and subsidies from local governments outside the major cities, while the use of renewable energy and the simplification of grid-connection procedures are also expected to advance.
The market comprises a wide range of segments, including power infrastructure construction, mechanical and cooling infrastructure, general construction and civil engineering, racks and raised floors, power distribution and backup systems, fire protection and security equipment, and network cabling. Higher density and energy efficiency will be key sources of competitiveness. By application, customers include cloud service providers, colocation providers, telecommunications carriers, enterprises and governments.
In the competitive landscape, NTT Global Data Centers, Equinix, Digital Realty, KDDI Telehouse, SoftBank, major general contractors and hyperscalers are competing as major players. Key success factors include securing sites, ensuring a stable power supply, shortening construction periods and addressing environmental requirements. Modular construction methods, the use of BIM, and seismic isolation and vibration-control technologies are differentiating factors.
Growth drivers ahead include rising AI demand, the development of data centers for generative AI, the spread of 5G and the promotion of digital transformation. Potential barriers include tight power supplies, higher materials prices and a shortage of skilled workers. Market growth from 2023 to 2030 is expected to be approximately 15% to 20%, with expansion driven by regional decentralisation and the use of renewable energy.
