Greetings

Nuclear fission and fusion represent two of the most promising clean energy sources for addressing global challenges related to climate change and environmental pollution. Around the world, a broad spectrum of advanced fission reactor concepts and fusion technologies is under active development. Achieving these innovations requires highly mature materials and engineering technologies.

The Japan-China Symposium on Materials for Advanced Energy Systems and Fission & Fusion Engineering provides an important forum for discussing these critical materials and engineering issues that underpin the realization of next-generation nuclear energy systems. Since its inception in 1993, the symposium has been held biennially in Japan and China, contributing significantly to both countries—and to the broader international community—through advances in design, materials science, and engineering for advanced energy systems, including both fission and fusion reactors. It has also played a central role in fostering bilateral collaboration for more than three decades.

Following the severe impact of the COVID-19 pandemic from 2019 to 2022, the 15th Symposium (CJS-15) was successfully held in Leshan, Sichuan, China, on September 4–6, 2024, hosted by the Southwestern Institute of Physics (SWIP). The 16th Symposium will take place in September 15–18, 2026 in Toyama, Japan. Located in the central region of Japan’s main island, Toyama is blessed with beautiful coastal scenery to the north and impressive mountain landscapes to the south. Participants will have opportunities to enjoy the rich natural environment and cultural heritage of the area.

The symposium welcomes participants from all countries. As the organizers, we look forward to meeting you in Toyama, Japan.
