According to Japan''s 6th Strategic Energy Plan, battery storage will be increased as a distributed source of electricity closer to end users and within microgrids.
During normal times, household power outages in Japan are extremely rare. But it is not unusual for earthquakes and other disasters to cause widespread outages.
According to Japan''s 6th Strategic Energy Plan, battery storage will be increased as a distributed source of electricity closer to end users and within microgrids.
Japan''s energy storage policies, market statistics, and trends—from METI''s strategic plans and subsidy programs to deployment challenges.
With renewable energy accounting for 38% of the national grid (up from 22% in 2020), the island nation faces mounting pressure to stabilize its power supply. But how exactly does energy storage fit into this puzzle?
With its updated energy storage policy, Japan aims to achieve 45% renewable electricity by 2030 while solving the ultimate puzzle: how to store sunshine and wind like canned tuna.
With home, commercial, and industrial batteries expected to balloon in the years ahead – and grid-scale systems beginning to appear – harmonizing Japan''s split-frequency grid and introducing battery-dedicated legislation could rocket-fuel the industry.
Now that we''ve covered the benefits of battery storage and Japan''s growing interest, let''s dive into the Japanese government''s detailed policies on this promising technology.

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.
The $593 million worth of commercial energy storage systems recorded in Japan in 2023 could balloon to $4.15 billion by 2030, InfoLink reckons, with “industrial adoption expected to scale faster,” according to the data company.
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.
Energy Security: Storage batteries are key to stabilizing Japan’s energy system. Given Japan’s limited natural resources and dependence on imports, combined with its vulnerability to natural disasters, investing in reliable and sustainable energy solutions is critical.
The “Storage Battery Industry Strategy” document from METI sets out three key targets: Boost Domestic Manufacturing: Japan aims to ramp up its domestic production of automotive storage batteries to 100 GWh by 2030, with a long-term goal of reaching 150 GWh annually. This move highlights the potential for foreign companies to invest in Japan.
Japan’s government called the package of energy policies and their targets “ ambitious.” Energy security considerations may affect the progress and pace of decarbonization in the electric power sector.
