Koban is a brand of rotary hooks, shuttle hooks, and bobbin cases—key parts that determine the work performance of sewing machines. 


In addition to being strong enough to endure rotations at high-speeds of 12,000 revolutions per minute, industrial sewing machine parts require exceptional levels of precision to the degree of a micrometer. With the high technological standards allow Koban to fulfill these needs. 


Koban continues to be the trusted choice throughout the world. Because of this reason, we are happy to bring together Koban and you

 Message from Hitoshi Sato (Presedent of the Koban):

Our story began in 1918 when a small textile factory was set up with a few weaving machines.

Years later, it turned into metal processing industry. We started manufacturing Hooks and Bobbin Cases, 

key parts of industrial sewing machines, and "KOBAN" became the top brand highly evaluated by sewing 

industry around the world. In recent years, we are expanding our business to high precision parts

processing, centering on medical equipments, by making full use of our accumulated technical strength

and quality assurance system. In order to respond widely to customer's needs, we are steadily promoting

strengthening of the system, such as acquiring the international standard of medical equipments, ISO 13485.


Overcoming the raging waves of social conditions, we will mark the 100th anniversary in 2018. This is all
