Greetings from the President

Suiryo Plastics is a comprehensive manufacturer of automotive plastic parts, of which Mitsubishi Motors is the parent company. Since our founding in 1968, we have been manufacturing a wide range of automotive interior and exterior parts from instrument panels, bumpers, door trims, consoles, etc. by making full use of our many years of expertise in manufacturing and our unique technical capabilities. We strive towards creating new values every day by consistently taking on all aspects of the process from technology development, to the design, molding, coating, and assembly, in accordance with the needs of the customer.

The automobile industry is currently undergoing a major transformation period amid the megatrend towards CASE amid calls for resin utilization and weight reduction. As such, we are receiving even more interest about the resin parts that we manufacture. In addition, nowadays, not only is weight reduction required to guarantee safety, but the colors, textures and aesthetics towards luxury for the next generation must also be satisfied.

Following our Code of Conduct to be “Small but beautiful,” instead of pursuing scale, we wish to return to our origins in manufacturing, and strive to improve the quality and function of each product, as well as providing an enriching life for local communities and society as a whole.
We would very much appreciate for your continuous support in the future.


President: Tetsuo Obana
