President Yoshikatsu Ohmori

Continuing to build trust with our customers with our technological expertise and human resources. These are the sources of growth at Yamamoto Seisakusho.

Ever since it was founded in 1967, Yamamoto Seisakusho has done its best to steadily deliver products that are a perfect match for the needs of its customers as one of the leading fineblanking companies. 

As a company that has fulfilled its mission for many years and continued to maintain the trust of its customers, we are proud of our technological expertise that helps us open the future and for our human resources that are the result of our education program. 

In addition to our four domestic facilities (Head office plant,Head office second plant, Yamagata plant and Ena plant), we have also established Yamamoto FB Engineering, Inc. in Kentucky in the United States. We produce high precision, pressed parts, mainly with the latest fineblanking machines, with very little deviation in specifications.

In addition to providing a stable supply of high quality products, Yamamoto Seisakusho is also focusing on reducing delivery times. By consolidating every part of production from receiving orders, designing dies, mass production and to delivery of products, and increasing the speed of communicating information between our facilities, including those in the United States, we are able to greatly reduce our delivery times. 

We hope to remain a leading company in the fineblanking and pressing die fields by maintaining an environment in which all of our employees can demonstrate their abilities in safe and secure conditions.
