Yanmar – Lean Characteristics
Leveled Production (Heijunka), Kaizen, Visual Management
Yanmar is a Japanese high-performance diesel engine manufacturer headquartered in Osaka. The company was founded by Magokichi Yamaoka in 1912. Born to a poor farming family and having witnessed the hard life of many farmers, Magokichi had a strong desire to “reduce the burden of the common laborer through the power of machinery”. Under his leadership, the company developed and released the world’s first commercially viable small diesel engine in 1933, which was well suited to the demands of agricultural application and made farming work easier and faster for many farmers. Magokichi’s legacy of innovation and environmental awareness have been reflected in their high-quality products.
The Yanmar Biwa Factory was established in 1955 and is located near Lake Biwa in Shiga Prefecture. The factory is fitted with cutting-edge production equipment and has developed itself to be a highly flexible plant to meet the diverse needs of their customers. They produce a wide range of vertical water-cooled diesel engines in a high-mix low-volume production environment. The factory achieves flexible manufacturing through leveled production also known as Heijunka in Japanese.
The factory actively promotes and facilitates kaizen activities and great examples of kaizen ideas implemented are on display. The factory tour also features effective use of laser guided vehicles (LGV) as well as excellent visual management tools used throughout the shop floor.
