In April 2026, the Ministry of Economy, Trade and Industry (METI) announced its initial selection of regions designated for promoting Green Transformation (GX) industrial hubs. While this announcement was limited to the prefectural level—with specific municipalities to be finalized later this summer—it already outlines a critical direction for companies evaluating location strategies for data centers and semiconductor-related industries.

A particularly noteworthy takeaway is the shifting focus from the traditional concentration in the Greater Tokyo Area toward a nation-wide, decentralized model that prioritizes power availability and decarbonized energy sources. Driven by the surge in AI demand, power consumption by data centers is skyrocketing. Consequently, discussions around GX policies and data center location strategies are increasingly becoming intertwined.

A GX Strategy Focused on “Nationwide Distribution”

A key feature of this GX regional selection is its classification into several distinct models, such as “Petrochemical & Industrial Clusters,” “Data Center Hubs,” and “Decarbonized Power Utilization Models.” This indicates a strategic intent to distribute industries across the country based on power infrastructure and existing industrial foundations, rather than pursuing mere urban development.

On the other hand, the relatively low number of selections in the Kansai region (Osaka and surrounding areas)—which already boasts a major presence as a data center hub—has raised eyebrows. This likely reflects an intentional policy to avoid over-concentration in specific areas and to maintain a balanced load across the nation’s power grids.

Until now, large-scale data centers in Japan have continuously concentrated in the Greater Tokyo and Kansai areas. However, with the exponential growth in demand for AI-driven infrastructure, regional decentralization is becoming inevitable from the standpoint of both grid load management and power procurement.

One symbolic move in this direction is the city of Utsunomiya’s initiative to attract large-scale data centers. Its plan to leverage land adjacent to a TEPCO Power Grid substation to secure an estimated 400-megawatt supply capacity is drawing significant attention as a model for data center development directly linked to power infrastructure. With other municipalities in Tochigi Prefecture also actively courting developers, the entire Northern Kanto region is emerging as a major new alternative hub.

An Era Where Decarbonized Power Determines Data Center Locations

What is particularly interesting about this GX strategy is the inclusion of the “Decarbonized Power Utilization Model.” In the future, data center site selection will likely place a premium not just on securing land, but on proximity to stable power sources, including renewable energy and nuclear power.

For instance, the Kashiwazaki area in Niigata Prefecture has long attracted attention due to its proximity to a nuclear power plant. In Kagoshima Prefecture, rumors are circulating about large-scale data center developments by Taiwanese companies around the Satsuma-Sendai area. Furthermore, areas facing the Sea of Japan, such as Tomakomai and Ishikari in Hokkaido, as well as Akita Prefecture, are generating high expectations for their connectivity to offshore wind power.

The Sea of Japan coast, in particular, overlaps heavily with promising areas for future offshore wind development, making it highly compatible with the GX strategy. The model of directly supplying massive amounts of renewable energy to power-hungry infrastructure is expected to gain further traction in policy discussions.

In addition, the “Guidelines for Data Centers in Harmony with Cities,” published by the Tokyo Metropolitan Government in 2026, is highly symbolic. The guidelines clearly demand that future data center construction incorporate energy efficiency, the use of renewable energy, and harmony with local communities. Data centers are transitioning from mere IT facilities into critical infrastructure that must be planned in tandem with regional energy policies and urban planning.

Whether or not a region was explicitly selected as a GX promotion zone in this round, locations that can “stably supply massive amounts of power” and offer “high connectivity to decarbonized energy sources” will undoubtedly strengthen their presence as the new frontiers for data center development.
