Superconducting technology is the one can make people's dream come true

High temperature superconducting materials were discoverd in 1986 and are used now in
various spheres of human life. 
The main advantage of the superconducting technology is to create bigger amount of
energy without generating carbon dioxide, this helps to noticeably reduce it in
the atmosphere.
Our engineer are always careful in managing the manufacturing process and are open to
fulfill the various needs of our customers.


CEO Greeting Sergey Lee

SuperOx Japan LLC was established in 2011 as a company engaged in the research, development, manufacture and sale of next-generation high-temperature superconducting (2G-HTS) wire in Japan, and has been able to enter its 11th year with the support of universities, companies, and research institutes in Japan and overseas.

Thank you from the bottom of my heart.

Now that the SDGs are a major issue, superconducting technologies that can reduce CO2 emissions and use energy efficiently are demonstrating great power in various fields such as electric power, railways, and medical care.

At the time of its founding, it started with only a few people and aimed to manufacture 100 km per year.

In 2021, 10 years after our founding, we added a new factory and increased the number of employees, and the current production volume has reached 300 km per year. As a result, it was very encouraging to be selected as one of the "Top 500 Fastest Growing Companies in Asia" (Financial Times, NIKKEI Asia) in 2021 and 2022.

SuperOx Japan will continue to work hard to meet the various needs of our customers, realize mass production of long-length wire with higher performance and lower cost than ever before, and aim to supply 1,000 km ~ 10,000 km per year in the future.

We will also expand the employment of electrical and mechanical engineers, develop technologies for superconducting wire applications, and contribute to the continuous development of society toward the future.

We will strive to ensure that superconducting technology, which can enable environmentally friendly, eco-friendly and clean energy supply, will be widely used in our life.

CTO Greeting Valery Petrykin

SuperOx Japan was established as the R&D company, and it has long track record of intensive research activities, which have built the foundation for the company success story.
Today one third of SOJ staff members arescientists with degrees in Physics, Chemistry, Materials Science and Electronics who ensure continuous products development and innovations.


Currently our company offers to the customers two lines of HTS wires products i) for liquid nitrogen applications and ii) for the applications in the high magnetic field, which are manufactured on the variety of substrates with different thickness ranging from 30 to 100 um In addition to that, we are ready to provide customized more challenging solutions and products using advantage of our long experience in the HTS wires production and excellence of our research and production teams.
