Japan''s 2025 Energy Storage Policy: Powering a Sustainable
A country with limited fossil fuels, frequent earthquakes, and a post-Fukushima energy identity crisis. Now imagine it leading the global charge in renewable energy storage.
In previous studies, the Fire and Disaster Management Agency surveyed prefectures and municipalities across Japan regarding the preparedness of emergency power supply. The survey results revealed that 100% of prefectures and 84.8% of municipalities had made progress in installing emergency power sources by local governments.
As policy, technology, and decarbonization goals converge, Japan is positioning energy storage as a critical link between its climate targets and energy reliability. Japan's energy storage policy is anchored by the Ministry of Economy, Trade and Industry (METI), which outlined its ambitions in the 6th Strategic Energy Plan, adopted in 2021.
Japan's energy storage landscape is shifting, pushed by household demand, corporate ESG mandates, and domestic battery manufacturing. The residential lithium-ion market, projected to grow at a CAGR of 33.9% through 2030, remains one of the fastest-expanding segments.
Therefore, there is any difference in the contents of emergency power supply in evacuation centers depending on the area where are applied the Disaster Relief Law within ten years, designated as a Nankai Trough Earthquake Disaster Prevention Measures Promotion Area, designated as an emergency response zone for the Tokyo inland earthquake.
Prefectures and municipalities promote emergency power supply measures in the power supply field. However, no method exists to evaluate installation locations, available time, and effectiveness during the urban emergency phase. Developing the methodology for assessing the emergency power supply measures is necessary.
In the commercial space, Japan's battery storage market was valued at USD 593.2 million in 2023 and is projected to reach USD 4.15 billion by 2030. While commercial installations currently dominate revenues, industrial adoption is expected to scale faster. Utility-scale storage is also gaining ground.
