ABOUT US

Company History

At the time we were founded, frequent typhoons in the Kyushu region were causing extensive damage to the telecommunications network, but there were no manufacturers supplying electrical wires in the Kyushu area, so we had to quickly establish a supply base. Naoto Yoshida , our founder, was encouraged by the Ministry of Telecommunications at the time (now NTT) to manufacture rubber-coated electrical wires to restore communications. Keenly aware of the great public benefit from such an enterprise, our founder founded Kyushu Electrical Wire Corporation (our predecessor) in 1951. The company name was later changed to DYDEN CORPORATION in 1963.
