Message from the President

I would like to express my sincere gratitude for your continued support.

"Contributing to society with advanced products"
This has been the management philosophy that Silver Kohki has maintained since its establishment in 1971.
Based on this philosophy, generations of managers and employees have continued to work single-mindedly to serve society through the production and sale of electric heating/resistance wires and ribbons.
Over the past 50 years, we have been striving to provide "advanced products" and "advanced service" to people in Japan and abroad with the aim of warming and enriching people's lives and the industries that support them, while passing on the baton of this desire.
We will maintain this philosophy as we continue to further develop the skills and knowledge we have cultivated over the years, and strive for sustainable growth and challenge ourselves to become a company that contributes to the realization of a sustainable society such as by promoting carbon neutrality.

President Takashi Tsukamoto
