Milestones in our history
Sumitomo Copper Rolling Works founded
Sumitomo Copper Rolling Works, which formed the basis of Sumitomo Electric Wire and Cable Works, the predecessor to Sumitomo Electric Industries, Ltd., was established in 1897. The nation was experiencing a severe recession as a reaction to an entrepreneurial boom following the Sino-Japanese War (1894-1895). In the wake of Sumitomo's acquisition of Japan Copper Manufacturing Co., Ltd. in March of this year, Sumitomo Copper Rolling Works was established.
Sumitomo Electric Wire and Cable Works established
Despite the remarkable development of the electric power business, the nation was still relied on imports for high-grade goods, and its technologies were immature. Lamenting the situation, Kankichi Yukawa, Director and Manager of Sumitomo Head Office, decided to further accelerate the electrical wire business to benefit both Sumitomo and the nation. In the fall of that year, Sumitomo Electric succeeded in the practical application of lead-coated power cables for the first time in Japan, demonstrating a further leap in technology. These cables were used for power transmission from Kyoto Dento's thermal power plant in Fushimi to Kyoto City.
