COMPANY INFORMATION
Greeting
After being established in 1972, Riken Kagaku Kogyo co., Ltd. has accumulated nad improved on numerous techonologies as a porous resin maker. The company's history has continued as the use of brush pens has expanded and developed. After more than 30 years, We have been able to find understanding of and acceptance for products using our porous resin technologies.
Since the establishment of our company, there have been two major oil crises, and a period high growth during the economic bubble and intense deflation as a result of the bubble's bursting; but we are finally seeing the end of that deflation. However, with the development of the personal computer, the stationery industry has decreased as people are traditional pens, pencils and paper less. As a result, our company is usually trying to improve the quality of brush pens so that people who rarely get a chance to use traditional brush pens can be able to do so more easily and casually.
Because our quality policy and process management based on ISO9001, we have confidence that Riken Kagaku Kogyo Co. Ltd. will continue to improve for our customers because of our excellent quality control.  Moreover, we are researching projects specific to our customers’ need faster than ever. Because our techniques and products are of the highest quality, we are continually developing methods for the application of our technologies not only for our traditional markets, but also for a wide variety of different uses and companies. Riken Kagaku Kogyo Co. Ltd., as an entrepreneurial company, feels that continued development and research are of utmost importance, and that not moving forward is essentially giving up and quitting.  We are striving to always further develop and refine our existing technologies and reliability and at the same time incessantly push the envelope of originality for our product research and development. Our mission is to steadily move toward the future while realizing the importance of further developing the results of this high technology for society.
