Total Electric Management Service Co., Ltd. (TEMS) is a partner company of the East Japan Railway Company (JR East). We maintain, manage and construct electrical equipment throughout the area managed by JR East, along with facilities belonging to JR Hokkaido, JR West, JR Freight and various other railway companies.

We were established in 1981 as Tokyo Electric Maintenance Co., Ltd., before merging with East Japan Electric Maintenance Co., Ltd., which oversees the Tohoku area, in 1999. The trust we have earned from our customers has seen us continually expand the scope of our work.
With outstanding safety management and top-quality maintenance, we play a vital role in society.

Maintenance of electric equipment for railways is the backbone of our business, and our work is an essential element in the safe and reliable operation of the railways we serve.
With our frequent, stringent inspections, our railways' passengers never have to question the safety of the trains they use.

We are actively innovating with technology such as IoT and AI.
It takes a lot of electrical equipment to keep a railway running, and we are constantly looking for better ways to detect and fix potential faults, such as monitoring technology and drones, enabling even more reliable operations.
This is accompanied by ongoing initiatives to improve the way we work.
We actively make use of machinery such as road-rail vehicles and mobile cranes to make it safer and easier to work in high areas.
Every employee is given a tablet for smart control of our equipment through our equipment management system. Employees' creativity has led to the development of a variety of apps that have enabled more efficient maintenance and management of our electrical equipment, improving productivity.

Our keenness to adapt to each new era and our uncompromising commitment to safety will remain a constant in the years ahead of us. Team TEMS has always worked together closely to ensure that our communities have safe and reliable railway services, and we are constantly striving to earn even more trust in our work as an electrical engineering company for the railway sector.
