Since its establishment, KOYO CHEMICAL has been engaged in joint R&D; with other companies, universities, public research institutes. And has been manufacturing and selling chitin, chitosan, glucosamine as the main materials extracted from crustaceans. Chitosan and glucosamine, in particular, have been used as functional health food ingredients and have contributed to prolonging the healthy life. Presently, chitosan is being used not only in the food industry, but also in a wide range of industrial, agricultural and cosmetic applications. Chitosan is not only useful in the fight against environmental pollution, but also has more potential, which is why we will continue to research and develop new materials, functions and applications.Since its establishment, KOYO CHEMICAL has been engaged in joint R&D; with other companies, universities, public research institutes.

We believe that the greatest asset of a company is its people. People are our employees, our customers and all the precious connections between people.
In order to build a deeper and stronger connection with our customers, we will continue to manufacture products of the highest quality and deliver them more quickly than ever before. Although the environment is constantly changing, we believe that there are certain things that a company should change and certain things that should remain unchanged. The "best quality" is something that cannot be changed. Products and services, on the other hand, need to be developed and changed. In this information society, the most important thing is to have the most up-to-date and accurate information, providing new suggestions for products and services.
By creating a fulfilling working environment that encourages our employees, more than half of whom are Tottori residents, to embrace positive challenges, we believe that we will be able to maintain the highest quality and respond to new changes. It is said that the surroundings shape the person. A better environment promotes a longer and healthier life, which in turn makes people kinder to the environment. We will do our best to contribute to this cycle.
