About Us

A Fail-safe Approach Is the Foundation of Our Business

Nippon Signal was founded in 1928 to develop domestic technologies for railway signal systems.

In the more the eight decades since, we have helped developing Japan’s transportation infrastructure, including the high speed Shinkansen service, and the high density timetables of urban train networks, into one of the safest and most comfortable networks in the world.

These everyday safe and comfortable railway services are made possible by Nippon Signal’s fail-safe technologies. This commitment to a fail-safe approach has remained the foundation of our manufacturing throughout, passed down through the years from the first semaphore signal to today’s systems.
