Our History

NUMATA Optics Machine Manufacturing Corporation, founded in 1957, has a long company life in comparison to the average corporate continuation term. We are continuing machining services for more than 70 years since we started from an intra-firm fabrication service in TOPCON in early1940s. Itabashi where we are providing services is the home place for optics industries of Japan and we have been developing and improving technologies by satisfying challenging and pioneering requirements from the industries such as clients and end users of products. “High precision and good finishing” is our technology and fabrication service. We believe “excessive quality”, which is our trade phase, is always included in and conceived behind the client requirements. Our old tooling and machinery were supporting “excessive quality” of the area that they worked with us.
