Japan's second call under the fiscal 2026 GX regional co-creation subsidy opened on 9 November and runs to 14 December 2026. It backs capital spending by companies that use decarbonised power and benefit the region where that power is generated, in two tracks: manufacturing facilities and data centres.
What is paid for
Eligible costs are the acquisition of buildings and similar assets, equipment, and system development. Land purchases are excluded. The subsidy rate is up to one-half of eligible costs, or up to one-third for large companies. The ceiling is up to ¥25bn, depending on the type of application.
The programme is open to companies of all sizes, from large groups to small firms, that meet its industry and decarbonised-power requirements. Eligible investment must be at least ¥1bn, or ¥2bn for large companies. Applications cannot be filed through an agent.
The power condition
The core test is electricity. Applicants must cover all of their demand with decarbonised power and procure at least 50% of it from within the same prefecture. The subsidy rate and the cap then vary with three factors: how much the project contributes to the area where the power source is located, how closely it is tied to that source, and what type of source it is. The source points applicants to the application guidelines for the detailed terms.
For a data-centre developer or a factory operator, the practical consequence is that site and power contract decide how much support is on offer, not only the size of the investment.
How to apply
The jGrants page takes only a statement of intent to apply: single or joint application, the type (manufacturing or data centre), and a contact name, telephone number and email address. The full application and forms are submitted through a separate system that the programme secretariat will announce to applicants. Log-in IDs for that system are sent to the applicant's email address.
