The history of Kohjin's biochemicals originated, when the production of yeast with the use of fermentation technique of wood-derived saccharide was started in 1962 (the 37th year of Showa) in the Saiki Factory which had produced dissolved pulp.
Since then, we have developed and improved the microbial fermentation technologies for about half a century and have accumulated affluent know-how and data. Making the most of this ingenious technologies and the biggest scale fermentation facility in the world, Kohjin satisfies various needs for pharmaceutical and food industries, and is also actively involved in the leading-edge biotechnology such as cell fusion and bioreactor.

Taking a scientifically approach to human life using biotechnology
Yeast is one of the most common microorganisms in human life, because it is vital to produce beer, sake, soybean paste, soy sauce, and etc. Kohjin started yeast culturing and subsequently has accumulated various technologies on culturing and refinement through treating various microorganisms, while has developed high value-added products making best use of our biotechnology and making much of those key words, "nature, health, and safety".
Our department is devoted to the feedstuff field which support dietary life, health food field which contributes to keep health maintenance, and medical and diagnostic product field. Kohjin totally supports people to have enriched human life through the products in these fields.
