Kyoto Fusioneering, a Japanese fusion technology startup founded in 2019, is moving its US headquarters from Seattle to Oak Ridge, Tennessee, investing $46.9 million and creating 51 jobs. The project centers on UNITY-3, a fusion test facility to be built at Oak Ridge National Laboratory with a deuterium-tritium neutron source, which has US Department of Energy funding. The deal Kyoto Fusioneering is moving its US headquarters from Seattle to Oak Ridge in Anderson County, Tennessee. It plans to invest $46.9 million and create 51 jobs. Tennessee's economic development department announced the move on August 11, 2026. About the company Founded in Japan in 2019, Kyoto Fusioneering makes equipment that future fusion power plants need, such as heating systems, blankets that capture energy and breed fuel, and fuel-cycle systems. It works with fusion developers in Asia, Europe and North America. Strategy The investment centers on UNITY-3, a first-of-its-kind fusion test facility to be built at Oak Ridge National Laboratory through a public-private partnership. It will use a deuterium-tritium fusion neutron source to test components under real conditions, and it has US Department of Energy funding. Being next to the lab puts the company inside a growing fusion and advanced nuclear cluster. Approvals and support Tennessee is backing the project through its Nuclear Energy Supply Chain Investment Fund. Some reports round the investment to $47 million. What to watch When UNITY-3 construction starts, how much federal money it receives, and whether other Japanese fusion and nuclear suppliers follow to Oak Ridge.
