Sumitomo Wiring Systems was established as an electrical wire manufacturer in 1917. Since then it has grown into a global business and a leading 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 in the time and 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 emerging nation markets. 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 Connecting Technology that we have built up in our business in wiring harnesses for automobiles.
