Yamamoto's Strength

CHAIRMAN Soichi Yamamoto

Since established in 1918, Yamamoto Co., Ltd. has specialized in the manufacture of agricultural machinery, including grain dryers and rice mill machines. During that time, we have been providing products and services that have satisfied our customers. Providing excellent products and services demands the growth of a company's employees. Indeed, "there is no terminal station on the road to improvement" There is no end to the spirit that seeks improvement. This spirit is the foundation supporting our company, and we have made it a constant precept, unchanged since our founding.
The only way we can receive the support of so many people both in Japan and overseas is to always create products and provide services that incorporate the customers' viewpoint.

PRESIDENT Takemi Yamamoto

Observers think that the market for agricultural machinery is now shrinking. We believe that in such a situation, we should continuously devote ourselves to research and development. In that way, our products and services, which feature labor-saving characteristics, rationality, and efficiency, will be increasingly utilized.
We are also actively expanding our business in the environmental sector, which is now the focus of attention. We offer proposals for new products by making the maximum use of our R&D capabilities and the three "seeds" of our company; "combustion", "selecting", and "cutting" technology. We will continue to advance into the future in partnerships as a company with the responsibility for providing safe and secure agricultural products and as a company that is a citizen of the regional and global community.

Our Vision

Our staffs transcend the sector boundaries of technology, sales and manufacturing , checking the product concepts and functions from every possible perspective. The result is a complete new product or service that has constantly been improved.
