History
Tradition and for the next generations
In 1909, three craftsmen, OHNO Kozaemon, NAKAMURA Kakichiro and ONO Mohei, began producing a cocoon cleaning/unwinding agent in a barn of the incense shop Ohno Kungyokudo. This product – later named SILKREELER – dramatically improved silk yarn spinning productivity, and contributed to establishment of mass production technology in the silk industry. They carried out further research and development and continued to supply products e.g. scouring agents and oil agents for the textile industry, which was the key industry of the time. In 1914, the company became Ohno Kogyo Seiyakusho by general partnership, and in 1918 Dai-ichi Kogyo Seiyaku (DKS) was established. In 1923, DKS opened a representative office in Shanghai, which was the first internationalization step for the company. R&D department was born in 1926, and ever since, the company continuously grew by increasing production plants and establishing subsidiaries in and out of Japan. DKS celebrated the 100th anniversary in 2009, and most recently, a new plant was constructed in Kasumi, Yokkaichi, in 2015.
