Key facts
- Japan is implementing a cybersecurity certification requirement for storage batteries connected to its power grid.
- As of July 1, 2026, no Chinese storage battery manufacturers have received this necessary approval.
- The lack of certification could effectively bar Chinese-made storage batteries from the Japanese market.
None of China's storage battery manufacturers have received cybersecurity clearance from Japan's government, despite an upcoming requirement that such equipment needs certification to connect to the power grid. The deadline for this certification is approaching, and the lack of approved products from Chinese companies could lead to their de facto exclusion from the Japanese market. This situation highlights potential trade friction and cybersecurity concerns in the energy sector.
