The history of Nihon Nohyaku Co, Ltd. comprises a major part of the history of Japan's agrochemical industry.
In the early 1920's, Furukawa Mining Co., Ltd. (now Furukawa Co., Ltd.) used a by-product of copper refining to successfully produce lead arsenate, the first agrochemical to be registered in Japan. This project was soon transferred to Asahi Denka Kogyo Co., Ltd(now ADEKA CORPORATION).
In 1928, the Agricultural Chemical Department of Asahi Denka Kogyo Co., Ltd.(now ADEKA CORPORATION) and Fujii Seiyaku Co., Ltd. merged to form Nihon Nohyaku Co., Ltd., Japan's first agrochemical manufacturing company.
For nearly 80 years, Nihon Nohyaku has been a leader in the Japanese agrochemical industry. The company has been developing agricultural technology and applying it toward the expansion of its business to include such sectors as pharmaceuticals, fine chemicals, environmentally safe chemicals, and gardening.
