Three Good-ism
Good to Partners Good to Society Good to Yourself
Our company traces its origins back to 1920, when we began importing organic rubber chemicals—such as vulcanization accelerators and antioxidants—from Bayer (Germany) and supplying them to Japanese manufacturers. Over a century later, we now source products from a wide range of countries, not just Germany, and primarily supply domestic manufacturers. Together with our three affiliated companies, we form the Heisen Group, serving clients across diverse industries including electronics, machinery, automotive, construction, and more.
