In the over 75 years since our founding in 1934, SEC CARBON has experienced a multitude of events during every era to become the SEC CARBON we are today, from the devastating damage to our Naruo Plant at the end of WWII, the transfer of our plant from Nishinomiya City to Fukuchiyama City in Kyoto, to the partnership and merger with Showa Electrodes and Kyowa Carbon. However, despite all these drastic changes, there is one thing that has remained the same, our passion for manufacturing. We are constantly looking at what is coming next, and we have been passionate about delivering and providing products that society requires. In 2009, the head office was moved to the 6th floor of the Amagasaki Front Building. In 2011, we have started to take on new challenges such constructing a new plant, within the Kyoto Plant, dedicated to the production of SK-B. You will not be disappointed in our continuing development and progress in order to answer to the expectations of our customers.
