With strong ambitions towards the energy transition and a liberalised power market structure, Japan is one of the most promising markets for grid-scale storage in Asia Pacific.
Japan''s energy storage policies, market statistics, and trends—from METI''s strategic plans and subsidy programs to deployment challenges.
This report by Blackridge Research and Consulting provides detailed insights into market dynamics, storage technologies, regulatory frameworks, and challenges influencing the

For the scheme ‘Support for the introduction of energy storage systems for home, commercial and industrial use’, the Japanese government has allocated around JPY9 billion (US$57.48 million) from the FY2023 supplementary budget.
As a result, the annual potential storage capacity that can be practically developed is 180 to 420 TWh/year, and the power generation cost is 19 to 21 JPY/kWh, indicating that the new pumped storage power generation is a promising power storage system for the future.
Projects led by Hitachi Energy and JAPEX are already deploying batteries for grid stability and renewable integration. As policy, technology, and decarbonization goals converge, Japan is positioning energy storage as a critical link between its climate targets and energy reliability.
In this proposal, the specifications of the new pumped storage power generation plant were reviewed in line with the disaster prevention measures implemented by the government, in light of the prediction that floods and droughts may occur twice as often as they do currently owing to the climate change in the future.
