日本のASSB開発とサプライチェーン構築が加速、政府補助金は6億6,000万ドル (約1,057億円) に到達 (トレンドフォース調べ)

Japan's government has significantly expanded support for next-generation battery technologies, allocating $660 million in subsidies to develop all-solid-state batteries (ASSB) and advance the supply chain. Major automakers like Toyota, Honda, and Nissan are building pilot production lines targeting 2030 commercialization. However, Japan faces competitive challenges from Chinese LFP battery makers and international competitors like Samsung SDI, which are advancing rapidly in solid-state battery development.
