Gears that reliably transmit enormous power without loss.
Gears that have always been, and will always remain, essential components of industrial machinery.
Among these vital mechanical elements, we have focused on manufacturing large gears in particular since our founding, striving for high quality, high strength, and high precision to meet our customers' diverse needs.

Where we stand today is supported by years of accumulated technical expertise, a wealth of track record, the introduction of the latest equipment, and the tireless efforts of our excellent staff.
While the basic shape of a gear — teeth cut around a circumference — never changes, technological innovation never stops, from upgrading material heat treatment to improving gear finishing precision. We continue to evolve to keep pace with these changes.

Built on the trust and track record we have cultivated since our founding, we have built partnerships with many companies in Japan and overseas.
We will continue to earn our customers' unwavering trust by consistently meeting their expectations and requirements.
