■Our Principal Products and Services
Since our founding in 1951, we have contributed to the stable operations of railway operators across Japan by performing repairs and inspections of railway vehicle components, primarily electric motors and reactors.In recent years, we have further expanded our business domains, and we now also receive requests for the repair of general industrial electric motors and other non‑railway components, including the manufacturing of electromagnetic coils.

■Passing Down, Refining, and Expanding Our Proprietary Technologies
We consider it our mission to pass down and further enhance the various proprietary technologies we have cultivated over the years, including maintenance such as insulation renewal for DC traction motors and auxiliary motors, in order to meet the diverse needs of railway operators.
By continuing to support many operators, we will further refine these proprietary technologies and take on the challenge of expanding their applications.

■Contributing to Railway Operators and to Society
As a safe, reliable, energy‑efficient, and environmentally friendly mode of transportation, the social demand for railways continues to grow.
At the same time, in the face of recent societal trends that have made securing skilled personnel increasingly challenging for railway operators, we aim to contribute by leveraging the expertise we have developed—such as technological innovation and cost‑reduction efforts—to further enhance the safety and reliability of railway vehicle equipment.
Through these initiatives, we strive to help operators solve their challenges, provide added value, and ultimately contribute to society as a whole.
