The workshop highlighted that Japan's continued reliance on fossil fuel imports creates acute security vulnerabilities and trade-offs, particularly when intersecting with climate hazards and geopolitical tensions. Participants identified that public opinion can be a driver for the renewable energy transition if technology is perceived as viable, and suggested that Japan should pursue an energy resilience alliance with like-minded countries such as South Korea and Taiwan. The report emphasizes the need for deeper inter-governmental dialogue across Japanese ministries to integrate climate security into national defense planning and to mitigate supply chain risks associated with renewable technology, specifically reliance on China.
