Great pride in manufacturing while striving for more flexibility and higher quality

Riveting machines that securely fasten parts are a timeless technology that is required in all fields, from home appliances and clothing to automobiles, aircraft, precision equipment and medical devices.
In the 80 years since the company was founded by Hironao Tsubone, the first manufacturer of riveting machines in Japan, Koki Shokai has made a wide range of contributions to the domestic and international manufacturing industry with its original ideas and Japanese manufacturing spirit.
As a pioneer in the field of riveting machines, we started manufacturing pneumatic riveting machines in the early 1970s, which replaced the first strike type machines, and have remained a standard machine to this day.
In recent years, we have succeeded in developing the world’s first next-generation servo riveting machine, which has opened up new possibilities for higher value-added applications with advantages such as high accuracy, high speed and low environmental impact.
The founder’s spirit of constant improvement and providing more reliable opportunities is alive and well among us.
Koki Shokai will continue to meet the various needs of our customers around the world based on reliable technology and do our best to create a society where people can live in peace.
