Kyoto Fusioneering develops engineering systems for fusion energy plants, including gyrotron plasma-heating systems, fusion heat-cycle systems, and fusion fuel-cycle systems. The company is advancing integrated test plants UNITY-1 and UNITY-2, with UNITY-1 in the final stage of demonstrating liquid-metal loop power-conversion technology and UNITY-2 slated to begin integrated fuel-cycle demonstration in Canada in 2026. It is a 2019 spinout leveraging Kyoto University research and is actively partnering with research institutions and industry globally. Kyoto Fusioneering also participates in Japan’s FAST commercial-scale fusion demonstration project aimed at power demonstration in the 2030s. The company recently expanded its R&D hub adjacent to its headquarters to test individual fuel-cycle devices and systems. On the business side, it has commercial adoption of its gyrotron system in countries including the UK, US, Germany, and Czechia. Financially, the company reported a new combined equity and debt raise totaling ¥9.38 billion and a cumulative equity financing total of ¥16.26 billion. Kyoto Fusioneering develops fusion-plant equipment and systems including plasma heating devices, heat-extraction blankets, high-performance heat exchangers, and hydrogen-isotope transport pumps. The company is advancing UNITY-1 and UNITY-2 projects, including a UNITY-1 power-test plant now installing major equipment and planning a simulated-environment power demonstration around summer 2025. It has formed a joint company with Canadian Nuclear Laboratories (Fusion Fuel Cycle Inc.) and added industry experts to accelerate a fusion fuel-cycle roadmap. The firm is also developing gyrotron systems with industry–academia collaboration to test high- and multi-frequency oscillation, and is expanding operations through a new European subsidiary (Kyoto Fusioneering Europe Gmb). As of the press release it employed 133 people across headquarters, research centers, and overseas offices.
