“The Company Is Its People, and The People Are What They Believe”

 

The current environment surrounding Japanese industry necessitates the con-

tinuous creation of innovative technologies. It requires that companies

transform themselves through those innovations in order to survive in the

global economy. Amid this challenging environment, we at Yamamoto

Manufacturing strive to maintain and improve our high standards of

technology, quality and reliability based on unique  production methods

and know-how. Thus we adhere to the key principle that “quality is the life

of manufacturing." The employees of Yamamoto Manufacturing make this

principle part of their lives and devote their full effort to the pursuit of

quality. As a company and corporate community, we strive always to

exceed the limits of possibility.

 

People are the heart of any company, in any era. Moreover,

people are what they believe. That is why I'm committed, under my

philosophy that "The company is its people, and the people are what they

believe," to the company's eternal progress and the happiness of

employees by doing the best I can to encourage everyone to seek self-

improvement and the highest purpose through dedication to excellence

in their work.
