Since its launch in March 2023, KF’s blog “THE FUSION ERA” has grown into a hub for sharing our journey in fusion energy—with over 60 articles published to date!
From deep-dive technical explainers and event reports to behind-the-scenes stories from new site launches, THE FUSION ERA offers a comprehensive look into the many facets of our activities.
In this latest post, we’ve curated a selection of past articles that highlight our three core technology areas:
🔹 Gyrotron Systems
🔹 Fusion Thermal Cycle Systems
🔹 Fusion Fuel Cycle Systems
By organizing our technical articles into these categories, we hope to give you a clearer picture of the technologies driving our mission to realize practical fusion energy.
Gyrotron Systems
Our blog posts on gyrotron systems take you inside this essential technology—exploring how it works and highlighting real-world testing activities. Here are a few featured articles:
- THE FUSION ERA – Fusion 101 / Reporting on the Gyrotron Test
- THE FUSION ERA – Fusion 101 / Inside the Gyrotron System: How it Works
- THE FUSION ERA – Exporting Kyoto Fusioneering’s Gyrotrons to the UK
Through these stories, we share both the technical foundations of gyrotrons and their role in advancing global fusion research.
Fusion Thermal Cycle Systems
Our Fusion Thermal Cycle System is designed to harness the energy of fusion reactions and convert it into electricity or hydrogen—turning scientific achievement into practical energy.
On the blog, we dive into topics such as our integrated test plant UNITY-1, the breeding blanket that extracts and transfers energy, and the advanced materials capable of withstanding the extreme environments of fusion.
Here are a few featured reads:
- THE FUSION ERA – The Breeding Blanket’s Essential Role in Fusion Innovation
- THE FUSION ERA – The Necessity of Fusion Materials Testing: The Role of Irradiation Facilities
- THE FUSION ERA – KF’s Involvement in the LIBRTI Programme
- THE FUSION ERA – Fusion 101 / A Closer Look at Our Liquid Metal Technology
- THE FUSION ERA – Fusion 101 / The VST Explained: Unlocking Tritium Extraction
Fusion Fuel Cycle System
The Fusion Fuel Cycle System is essential for sustaining fusion reactions by ensuring a continuous and reliable fuel supply to the plasma core. On our blog, we introduce UNITY-2, a groundbreaking project in Canada developed by Fusion Fuel Cycles Inc.—our joint venture with Canadian Nuclear Laboratories (CNL)—along with the many devices and systems under active development in Japan.
Highlighted posts include:
- THE FUSION ERA – Fusion Fuel Storage: New Experimental Device Delivered!
- THE FUSION ERA – Fusion 101 / Introducing our R&D Work on the Fusion Fuel Cycle
We also share stories of collaboration and partnership with CNL and FFC, offering a closer look at the people and progress behind the technology:
Fusion 101 Series – Fusion Made Friendly
One of our most popular blog categories, “Fusion 101,” is dedicated to making fusion energy more approachable, especially for readers without a technical background. This series was created with “armchair scientists” in mind, helping them better understand the fascinating technologies that make fusion possible.
In addition to the articles highlighted above, here are a few more entries from the series:
If you’d like to dive even deeper, we’ve got plenty of extra content available in Japanese too.

- THE FUSION ERA – ゴリ文が学ぶ #2 / フュージョンエネルギーを学ぶ虎の巻たち
- THE FUSION ERA – ゴリ文が学ぶ #3 / フュージョンエネルギーに関わる元素を周期表で見てみた
All of these blog posts can be found in the NEWS section of our website. The page includes a sorting feature, so you can easily filter by category—for example, selecting Technology will display only our technical articles and news releases.

We’ll continue to share updates on our projects and the progress of our technologies, so we hope you’ll keep following THE FUSION ERA blog for more insights!
