Sumitomo Wiring Systems was founded as an electrical wire manufacturer in 1917. Since then it has grown into a leading global company in wiring harnesses for automobiles. Active on the world stage, it has built a solid business foundation by clearly recognizing and adapting to changes over time and in the field, using technology cultivated through its experience with electrical wires.

Right now the auto industry is in the midst of a major paradigm shift involving factors ranging from changes in automobiles’ relationship with the environment and their role in people’s lives to responses to expanding markets in emerging nations. By consistently anticipating future changes and trends, we will push ahead with the development of new products and technologies—always with the customer’s perspective in mind—based on the "Technologies-Connect with the Best" that we have built up in our business in wiring harnesses for automobiles.
