Japan is preparing a major financial push to encourage companies to switch fully to clean electricity, unveiling a ¥210 billion ($1.3 billion) subsidy programme aimed at boosting renewable energy demand and supporting regional economic growth.
A senior government official said the funding, which will be spread over five years from fiscal 2026, is part of Tokyo’s broader effort to meet its climate targets and cut dependence on imported fossil fuels. The initiative comes as the country struggles with delays and rising costs in key wind and solar projects.
Under the scheme, businesses that operate entirely on decarbonised electricity and contribute to local economies where the power is produced will be eligible for support. The subsidies could cover as much as 50% of qualifying capital investment costs. Data centre operators that meet the same clean-energy conditions will also be able to apply.
The Ministry of Economy, Trade and Industry is expected to begin accepting applications from eligible companies in the next fiscal year, according to Juntaro Shimizu, who heads the ministry’s Green Transformation policy group.
Japan, the world’s fifth-largest carbon dioxide emitter, has set a goal for renewable sources to provide up to half of its electricity supply by fiscal 2040, while nuclear power is expected to contribute around 20%. In fiscal 2023, renewables accounted for just under 23% of the power mix, with nuclear at 8.5%.
Progress toward these targets has been slower than planned. Offshore wind developments, seen as central to Japan’s clean energy transition, have been hit by cost inflation, while large solar projects have faced resistance from local communities.
The new subsidy programme is part of Japan’s “GX 2040 Vision,” a national strategy that links decarbonisation with industrial policy to drive long-term economic growth. As part of this framework, the government plans to designate “GX Strategy Regions” — areas with access to low-carbon power that can host new industrial clusters.
Local authorities and private companies will jointly submit development proposals, after which the national government will select regions for support through financial incentives and regulatory changes. Applications from local governments are expected to open later in the current fiscal year.
Officials say the measures are designed not only to accelerate the energy transition but also to revitalise regional economies by attracting investment tied to clean power sources.
