Denka Company Limited (デンカ株式会社, Denka Kabushiki-gaisha); formerly Denki Kagaku Kogyo Kabushiki Kaisha (電気化学工業株式会社) is a Japanese chemical company, established in 1915 and headquartered in Tokyo, manufacturing organic and inorganic chemicals, cement, special cement additives, electronic component transfer materials and food packaging materials.[2] The company is listed on the Tokyo Stock Exchange and is a constituent of the Nikkei 225 stock index.[3]


In 1912 Tsuneichi Fujiyama founded a carbide business, Hokkai Carbide, in Tomakomai, a village in Hokkaido. One year later, Fujiyama patented his own process of producing cyanamide, the continuous cyanamide process.[4] In 1913, Fujiyama with the help of 22 venture capitalists incorporated a reorganized Hokkai Carbide as Denki Kagaku Kogyo, the current company. Despite its legal status as an independent corporation, Denka was a Mitsui-related company.[5] The company changed its name from Denki Kagaku Kogyo to Denka Company Limited 2015.[6]
