Technical FAQs 4

Are batteries commercialised in Japan?

batteries are commercialised. Japan imports about 90% of its primary energy requirements and is vulnerable to energy supply disruptions overseas. In recent years, new energy security factors have been studied.

What is Japan's storage battery industry strategy?

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.

Why is battery storage important in Japan?

They store solar power for use at night and ensure a steady green energy supply, crucial for Japan’s sustainability goals and the Green Transformation (GX) initiative. In short, battery storage is now crucial due to the boom in solar power and the increasing demand for green energy from emerging industries.

How big is Japan's battery storage market?

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.
