Our past and our future "Our company was founded in April 1949 with the determination of the first president, Yasushi Okuda, who was an engineer for the Hokkaido Government, to provide excellent castings that would contribute to the industrial development of Hokkaido. Since then, we have consistently strived to provide high-quality products from the perspective of our customers.
Currently, we supply over 800 types of castings, mainly made of stainless steel, heat-resistant cast steel, and wear-resistant cast steel, to about 130 customers throughout Japan. In 2015, we updated our VRH casting/VRH molding equipment to alkaline phenolic molding equipment, and in 2017, we updated our ISO 9001 certification to ISO 9001:2015, continuing to enhance our system for further improvement of product quality.
With the casting-making technology accumulated over more than 70 years of history and the ability to respond to the needs of the new era, we aim to become a casting factory that can deliver to the world from Hokkaido."
