With Gratitude, Our 60th Anniversary of Incorporation

It is with gratitude that this July we celebrate the 60th anniversary of Minebea Co., Ltd.'s incorporation. I thank everyone for the great blessing of support which has made this achievement possible.

In July 1951, our company was founded in Tokyo's Itabashi Ward as Japan's first manufacturer specializing in miniature ball bearings. The company was formed after the war by engineers from the former Manchuria Aircraft Company upon their return to Japan from Manchuria, and their dreams and passion were focused on the growth of the aircraft industry. In the chaotic Postwar period, they struggled like everyone else at the time to build the foundations of their business.
Today, 60 years later, the company has grown to include facilities in 18 countries around the world with over 55,000 employees. We provide the world with products that are essential to everyday life, from ball bearings to machined components, rotary components, electronic devices and components, and more.

With a commitment to craftsman that reflects the same dreams and passion of our company's founders, we will continue striving to be a company that serves the needs of all our clients.

We thank you for your continued support.
