Message from
the President
We aim to become a centennial company.
We will continue to create a better future based on history and trust.

It has already been 80 years since Ooyama was founded. With the shifting global situation and rise of AI in recent years, the world is changing more than ever before. But there is one thing that our company has valued since our founding. That is customer trust.

Because Ooyama is a trading company without its own brand, we have earned the trust of our customers by sincerely engaging with their requests, and exceeding their expectations. This is why we are building a system deeply aligned with our customers, in which sales staff not only propose products, but often even select suppliers and see the project through to delivery. As a result of the trust we have built, we get business inquiries from a wide range of industries from automotive to housing equipment. Consequently, this allows us to establish a business foundation that is less swayed by the business climate.

In addition to trust, another thing that I value as the 4th president of the company, is to listen to our employees. The people most sensitive to what society needs of us, are the employees out in the field interacting with customers. In the past, we have even been known to open a new sales office based on the opinion of a single salesman, and significantly changed the structure of our services. In order to better value the motivation and spirit of endeavor of each and every employee, we are paying more attention to changes in society and work-styles in the field. And we are also putting more effort into improving our internal systems.

Ooyama is sustained by the strength of our employees and many partner companies. This is why it is essential that we keep growing into the future. In the fall of 2024 we will open a new sales office in Himeji, as we expand our business towards our goal of 10 billion yen in annual sales. Moreover, as a company involved in manufacturing, we intend to further promote initiatives that are beneficial to the global environment.

As we look toward our 100th anniversary, we will continue striving to be the kind of company the world needs, and create a better future together with you all.
