Move enhances Opportunities for Collaboration with whole UK Fusion Sector
Kyoto Fusioneering, a Japanese company specialising in engineering fusion energy power plants, has established its new UK base at the Culham Campus – the home of the UK’s fusion sector for many decades – following several years based in the Thames Valley area. The Culham move marks a bold new chapter in the Company’s mission to accelerate the development of fusion energy, deepen its relationship with the UK Atomic Energy Authority (UKAEA), and collaborate with other domestic and international fusion companies on the site within the thriving UK fusion ecosystem.

Culham Campus is a world-renowned hub for fusion research and provides an ideal location to support Kyoto Fusioneering’s vision and growth ambitions. The move brings the Company to the heart of the UK’s fusion energy community and builds on a successful track record of collaboration with UKAEA. By joining the vibrant innovation environment at Culham Campus, the company is well-positioned to access world-class fusion facilities and expertise, fostering collaboration with UKAEA and other world-leading technology companies to accelerate the delivery of sustainable fusion energy.
“This move represents a major milestone in our international strategy,” said Satoshi Konishi, CEO and Co-founder of Kyoto Fusioneering. “Relocating to Culham Campus allows us to work more closely with UKAEA and other key players in the fusion community, while also giving us the flexibility to grow our UK footprint as our activities expand. We are grateful to UKAEA for making the move as seamless as possible and for opening the opportunity for us to join them at Culham.”
“We are delighted to welcome Kyoto Fusioneering to Culham Campus,” said Tim Bestwick, Deputy CEO of UKAEA. “They have already been a valued partner, and their presence here will help strengthen the innovation ecosystem as we all work toward making fusion a commercially viable energy source.
Culham Campus, managed by UKAEA, is a globally recognised centre of excellence for fusion energy and related technologies. Kyoto Fusioneering’s presence on the campus will not only enhance collaborative research opportunities but also provide a launchpad for the company’s long-term growth in the UK.”
The Company plans to scale its ever-growing UK operations on campus over time, contributing to job creation, knowledge exchange, and the UK’s leadership in global fusion energy development. As part of these efforts, Kyoto Fusioneering has been actively delivering advanced technologies to key players in the UK fusion ecosystem. In March 2024, the Company delivered a cutting-edge gyrotron system to UKAEA, marking a significant milestone in supporting national fusion research initiatives. In January 2025, Kyoto Fusioneering delivered a gyrotron system to Oxfordshire-based fusion developer Tokamak Energy. The gyrotron aims to improve the performance of Tokamak Energy’s high-field spherical tokamak, ST-40, and supports its facility to achieve key research goals.
Kyoto Fusioneering has been actively engaged in a wide range of initiatives in the UK. As part of R&D efforts related to LIBRTI, a breeding blanket test project launched by UKAEA, the Company is collaborating with universities and local companies. Kyoto Fusioneering has also secured a contract to supply getter beds for H3AT, the tritium-related facility.
In March this year, Kyoto Fusioneering, with lead partner J-Fusion (Japan Fusion Energy Council), brought together UK Minister for Fusion, Kerry McCarthy, the Ambassador of Japan to the UK, his Excellency, Hiroshi Suzuki and British and Japanese fusion-interested organisations at the Japanese Embassy in London to celebrate growing collaboration between the two nations on this critical technology. Kyoto Fusioneering is supportive of efforts by the Governments of Japan and the UK to formalise this growing collaboration further.
The Company also recently met officials from the Japanese Government’s Ministry of Education, Culture, Sports, Science, and Technology (MEXT) at the new offices in Culham to discuss further collaboration between Japan and the UK in fusion and how Kyoto Fusioneering might support this.
