Founded in 1912, YANMAR succeeded to develop the world's first commercially viable compact diesel engine in 1933. Since then, continuing to embody our company founder's philosophies of “Wasting not one drop of fuel” and “Releasing people from the burden of heavy labor”, we have been a pioneer in the production of high-performance industrial engines.

In 2012, we became the world’s first engine manufacturer to clear CARB (California Air Resources Board) Tier 4 (19-56kW class) emission regulations, and in 2013 we were also first to obtain certification under the Swiss Ordinance on Air Pollution Control (18-37kW class). Carrying out advanced research based on engineering skills fostered over years of experience in engine development, YANMAR will continue to pursue cutting-edge technology capable of clearing environmental regulations in all countries.

At our Biwa Factory in Shiga Prefecture, we operate a highly efficient automatized production system which enables multiproduct-mixed production of over 2,000 engine models. This is our industrial engine “Mother Factory”, delivering high-quality engines for a wide range of industrial machinery both in Japan and overseas.

Via our global network, we can respond to the varying customer needs and regulatory requirements unique to each part of the world, enabling us to deliver engines which are tailored to our customer’s demands.
