Prof. Satoshi Konishi co-founded Kyoto Fusioneering in 2019. With a Ph.D. in Engineering from the University of Tokyo, Satoshi brings four decades of expertise in R&D, specializing in fusion technology, advanced nuclear system design, and tritium engineering, including significant contributions to the ITER project. He holds dual roles as Chief Fusioneer, overseeing technology development, strategic planning, and execution, and as CEO, a position he has held since 2023.

Prof. Keishi Sakamoto joined Kyoto Fusioneering in April 2021 as an Executive Officer. He has been engaged in R&D for plasma heating technology for several decades, most recently at the National Institute for Quantum Science and Technology in Japan. In particular, he has been extensively involved in the development of gyrotrons, high-power millimeter-wave generators based on the theory of relativity. As a result, Keishi was the first in the world to simultaneously achieve an output energy of 1 MW an energy conversion efficiency of more than 50%, with continuous output. For his work, he has received awards from MEXT in Japan and the European Physical Society Plasma Division (Innovation Prize). He is now a Specially Appointed Professor at Institute of Advanced Energy, Kyoto University, and has a Ph.D. in Science from Kyushu University.

Dr. Christian Day joined Kyoto Fusioneering in May 2024. He has spent decades in R&D for fusion fuel cycle technologies like vacuum pumping, tritium processing, and particle exhaust, most recently at the Karlsruhe Institute of Technology (KIT) in Germany. In particular, he led the systematic development of cryopumps for ITER through all technology readiness levels and pioneered the concept of “Direct Internal Recycling” to reduce tritium inventories, for which he received the first SOFT Innovation Prize in 2014. Christian contributed to more than 170 publications in refereed journals and had 50 invited talks globally at conferences. Before joining KF, he held the teaching position of Vacuum Science and Technology at KIT since 2009. He holds a Ph.D. in Technical Thermodynamics from KIT.

Colin joined Kyoto Fusioneering in Aug 2021. He is a physicist who did his graduate studies at KIT, Germany. His PhD was on heavy-ion cross sections and the link to astroparticle physics at the Large Hadron Collider at CERN (CMS experiment). As co-author of the hadronic interaction tool CRMC, he has deep knowledge in nuclear physics. After several years in the private industry in C-level roles, Colin joined Kyoto Fusioneering. He is the author of the SCYLLA high temperature fusion blanket concept and currently overseeing the technical development of the UNITY programme for fusion thermal cycle and fusion fuel cycle in Japan. He is also a visiting researcher at Kyoto University.

Mr. Kenichi Hayashi joined Kyoto Fusioneering in April 2022. He has been in charge of designing, manufacturring and testing the gyrotron system that KF has received. Prior to joining KF, he worked for CANON ELECTRON TUBES & DEVICES for 21 years. He was involved in research and development of high-power electron tubes such as klystrons and gyrotrons for accelerator facilities and fusion research facilities around the world. He eventually became the manager of the electron tube engineering department and the electron tube business division. He has an M.S in Electronic Engineering from Osaka University.

As Co-Head of Plant Technology, Yoshi leads the development of fusion fuel cycle and fusion thermal cycle technologies. He is involved in plant design projects for clients worldwide, leading the power generation test plant “UNITY-1” and the “UNITY-2” project in collaboration with the Canadian Nuclear Laboratories (CNL), which conducts demonstration tests of the fusion fuel cycle using tritium in a real-world setting. Additionally, he promotes the development of components and technologies required for plant operations alongside reactor design.
Before joining KF, he worked at Mitsubishi Chemical, where he was involved in heat balance and production management, equipment modification, and procurement. In his previous role at Mitsubishi Corporation, he managed financial derivatives and oil trading in Singapore and investments in low-carbon businesses in London.

Taka Nagao co-founded Kyoto Fusioneering in 2019 and served as CEO, where his leadership was instrumental in propelling our fusion venture from its origins as lab-scale R&D to a global enterprise. Spearheading strategic planning, fundraising, and the recruitment of top-tier talent, Taka was pivotal in shaping the company’s trajectory. In October 2023, Taka transitioned to the role of Representative Director and Chairman. Starting in April 2024, he assumed Director and Chairman, lending his expertise to guide and support the company’s management team while actively contributing to the establishment of a resilient and sustainable corporate framework.
Leveraging the expertise he cultivated at KF, Taka is expanding his activities to support startups and empower entrepreneurs. He holds a Master of Science degree in Mechanical Engineering and Science from Kyoto University.

Mr. Kiyoshi Seko joined Kyoto Fusioneering in April 2021 as an Executive Officer. Kiyoshi is responsible for business development, fundraising, and also PR and marketing. Prior to joining KF, he worked for Mitsubishi Corporation for almost 10 years, where he was involved in business development and strategic investments, including for the establishment of overseas JVs and cross-border M&As. After obtaining his MBA, he worked for Coral Capital, a leading VC firm in Japan, where he made several investments – including one in Kyoto Fusioneering before joining the company – mainly in the deeptech area. Kiyoshi has an M.S in Mechanical Engineering from Kyoto University and an M.S in Applied Physics from University of Tokyo, as well as an MBA from IE Business School, Spain.

Mr. Yuto Yoshioka joined Kyoto Fusioneering in November 2021. He has been expanding the Gyrotron business, focusing on its start-up and project management, and the development of UK-related business. In his previous position at a Japanese investment and trading company, after studying at the University of Indonesia, he was stationed in Jakarta, where he was engaged in the development of a natural gas project, the first operatorship (in which the company was responsible for business operations as the main shareholder) for a Japanese company at the time. Later, he worked as a trader of crude oil and derivatives in Singapore, where he expanded his business and profit. He was also in charge of power projects in Asia and the Americas. He graduated from Kyoto University with a bachelor’s degree in economics.

Since April 2022, Mr. Nakahara has served as the corporate strategy leader at Kyoto Fusioneering, overseeing business policy, organizational development, technology strategy including IP. He directs corporate affairs, business development, and joint development with overseas fusion energy organizations, including public institutions and start-ups, primarily in the JP, US and UK.
