Press Releases

Fujikura Ltd. (Director, President and CEO: Naoki Okada) has announced its capital investment of ¥5.6 billion in production expansion facilities for high temperature superconductors (hereafter HTS), for which demand is expected to grow in line with advancements in fusion energy development. This investment aims to secure a stable future supply system.
In fiscal year 2024, Fujikura executed approximately ¥6.0 billion in capital investment in expansion of its manufacturing facilities, with the goal of increasing production capacity for HTS to approximately three to four times the previous level by fiscal year 2027.
With this additional investment, production capacity is expected to increase by a further approximately twofold, enabling Fujikura to elevate its HTS production capacity to one of the world’s largest scales and further accelerate global energy innovation.

Fujikura’s HTS maintain superconducting properties even at higher temperatures and are capable of generating extremely strong magnetic fields.
These characteristics make HTS an essential material for superconducting magnets used in fusion energy reactors ^*1, which are expected to serve as next‑generation power generating systems that produce no carbon dioxide emissions during operation. Such magnets are indispensable for confining and controlling plasma at temperatures of approximately 100 million degrees Celsius.
In recent years, development of fusion energy reactors has accelerated both in Japan and overseas, with initiatives underway to realize magnetic confinement‑type fusion reactors during the 2030s. As a result, demand for HTS is expected to continue to expand over the medium-to long-term.

Fujikura has long been engaged in the research, development, and manufacturing of HTS, establishing world‑class technological capabilities spanning from materials design to mass production technologies.
The company has also been involved globally in fusion‑related activities, including investments in Kyoto Fusioneering Ltd. in Japan and Commonwealth Fusion Systems in the U.S., as well as being selected for a Framework Agreement by the UK Industrial Fusion Solutions Limited (UKIFS).
In Japan, the national fusion energy strategy has recently been revised, and further acceleration of development activities is anticipated.

Through continued provision of high‑performance HTS, Fujikura will continue to contribute not only to the realization of fusion energy but also to a wide range of superconducting applications, thereby supporting the achievement of a carbon‑neutral society.

*1 Fusion Energy Reactor
A fusion energy reactor generates electricity by utilizing the energy released when light atomic nuclei (such as deuterium and tritium) fuse to form another nucleus (helium). This process is the same phenomenon that occurs in the sun. It is said that one gram of fusion fuel can produce energy equivalent to approximately eight tons of oil. Fusion fuel can be extracted from seawater, and the power generation process does not emit carbon dioxide, making fusion energy a promising solution to global warming and environmental challenges. It is expected to play an important role in realizing a carbon‑neutral society.
