Japan’s AI data center market is projected to reach US$59 billion by 2035. Expanding demand for generative AI, LLMs and enterprise AI, the government’s digitalization initiatives, and advances in technologies such as GPUs and HBM are cited as the main growth drivers.
A research report released by the Japanese Market Research Center examines the projected size of Japan’s AI data center market in 2035, company trends, and forecasts and market shares by segment. It also points to the growing importance of edge AI data centers, alongside central hyperscale facilities, as demand for low-latency applications increases.
The spread of generative AI and LLMs is identified as the largest growth driver. Wider adoption of enterprise AI, the growing use of cloud AI, and the rise of sovereign AI are also expected to contribute to growth. Advances in GPUs, HBM and high-speed networking, as well as the expansion of GPU-as-a-Service, are cited as factors that will boost the market. The government’s digitalization strategy is expected to support the expansion of domestic computing capacity.
The market’s main constraints include rising power demand, the stability of electricity supplies, land shortages, cooling costs and earthquake risk. In particular, limited land availability is identified as a factor that will prolong the concentration of facilities in Tokyo and Osaka. Potential expansion into regional areas, higher-density deployments through the introduction of liquid cooling, and stronger seismic resilience and business continuity planning across infrastructure are also identified as issues for consideration.
Key players in the competitive landscape include NTT DATA, Digital Realty, Equinix, KDDI, Fujitsu, NEC, AWS, Microsoft and Google Cloud. The report also highlights specific initiatives, including Blackstone’s planned investment of approximately US$30 billion, the launch of NTT DATA’s AI agent services, and the partnership between KDDI and HPE.
