Riken Corporation is the highly-functional parts supplier for the automotive and other industries, whose root comes from the large and well-known research institute in Japan, "Rikagaku Kenkyusho."

Riken was established in 1927 for the purpose of commercializing the innovative piston rings manufacturing method invented by the said research institute. Since its foundation, based on the prominent technologies of material, machining, surface treatment and so on, Riken has grown to the worldwide piston ring supplier and the globally unique corporate group through expanding its product portfolio such as automotive parts, pipe fittings, thermal engineering, EMC and other industrial products.

In 2017, Riken celebrated its 90th anniversary, as well as the centennial of our root -"Rikagaku Kenkyusho", where Riken Group has inherited the spirit of "Iinnovation" and "Continuous Reinvention". With the inherited spirit and as a technology oriented corporate, we are committed to continuously enhance our technology and to create new products and new values that delight our valued customers.
Through pursuing the customers' satisfaction and delight, we will expand our business on a global basis and become a "global leading supplier of highly functional mechanical components."

On July 16, 2007, we experienced a terrible earthquake, "the Niigata Chuetsu Offshore Earthquake," which greatly damaged our production facilities in Niigata area. Thanks to kind supports extended by everyone, we were fortunately able to restore the damaged facilities and resume supplying to the customers in a suprisingly short time.
This experience gave us a chance to recognize anew the importance of fulfilling our corporate social responsibilities. Therefore, we have been enhancing not only safety, quality, but also the BCP (Business Continuity Plan) since then.

Also, we understand that being a leading corporate citizen, who contributes to the society, is essential to a sustainable corporate activity.

Therefore, we make the best effort to fulfill our corporate social responsibilities and to be trusted by all the stakeholders, such as customers, shareholders, employees, suppliers and local communities.
Each and every one of Riken Group will keep pursuing the further enhancement of the corporate value and the corporate growth.
