In the past, motorization developed with the needs of the times,

and civilization developed. Our lifestyles also prospered.

Now, as we face the "next 100 years",

we aim to live in harmony with nature and create a growing society.

We aim to create the ideal car-oriented society.

The automotive industry is currently facing a once-in-a-100-year paradigm shift, and the key is “CASE” or “Connected”, “Autonomous”, “Shared & Services”, and “Electric”. We are helping to accelerate the advancement of CASE. However, there is an ideal car-oriented society in the future which we, the automotive industry aim to create.


We aim to create and provide value.

Since our founding in 1929, the Sumitomo Riko Group has supported the automotive industry through the development of its anti-vibration rubber and hoses. As the world moves towards the development of the next generation of mobility, we will further develop technology and contribute to society from a safety, comfort, and environmental viewpoint, particularly centered around the “Autonomous” and “Electric” fields of CASE.

We will refine the power of materials and beyond.

Sumitomo Riko's core competence is the foundation of the development of products to meet the needs of customers. Polymer Materials Technology to create high performance raw materials based on "compound", "synthesis", and "modification" and Comprehensive Evaluation Technology to conduct in-house evaluations and assessments of the required performance and reliability of products. These two strengths are not only used to expand existing business, but also actively advance business development in new markets and fields.


We aim to create the next generation of mobility and society.

Countries all around the world are accelerating initiatives to achieve a carbon neutral world that essentially emits zero greenhouse gasses. For this to be achieved, it is essential that motor vehicles transition from engine vehicles to hybrid vehicles (HEV/PHEV), electric vehicles (BEV) and fuel cell vehicles (FCEV). Since our founding, we at Sumitomo Riko have steadily expanded our field of business and created new value by accurately ascertaining the direction of the times and the needs of the market. We aim to be a “Global Excellent Manufacturing Company” that is needed around the world and create the next generation of mobility and a brand-new world while faithfully abiding by the Sumitomo Spirit of “Banji-nissei” , “Shinyo–kakujitsu” and “Fusu-furi”.
