History Movie

Since the Company’s founding in 1897, Sumitomo Electric Industries, Ltd. has continued to take on challenges to achieve a prosperous and dream-filled future. In late 19th century, Japan was still heavily dependent on expensive imported electric cables. Sumitomo Electric decided to break ground with the electric wire business for the benefit of the nation. Starting with the production of copper and silicon copper wires, the Company played an important role in supporting the development of Japanese industries, succeeding in the first domestic production of high-voltage underground cables and the production and installation of the world's longest submarine cables.

120 years have passed since then. With its belief in the great potential of "innovation," the Sumitomo Electric Group will continue to contribute to the development of Japan and the world, both today and in the future.

The year 2017 marks the 120th anniversary of the founding of Sumitomo Electric. From an electric wire and cable manufacturer in Osaka 120 years ago, we have grown into a global leading company in automotive, infocommunications, electronics, energy and industrial materials industry. Take a journey through time and find out more about the defining moments in our history.
