Growing with our customers
as a partner providing creative solutions 

In the Plastic Division I, the Polymer Department I and the Polymer Department II deal in daily goods as well as commodity plastics for building and engineering materials. The Performance Plastics Department deals in high-performance resins and related materials for home appliances, office automation (OA) equipment, and electric and electronic products. The Automotive Products Department I and the Automotive Products Department II deal in plastic compounds and high-performance resins for automobiles and motorcycles.

We operate a total of seven plastic compounding factories across six Asian countries and Mexico, providing comprehensive support from material selection to processing. We are aiming to improve our ability to gather information by training local staff, which includes measures such as stationing plastic specialists at overseas locations and proactively promoting local staff to managerial positions. We also have our own warehouses overseas and are working to enhance our logistics functions. By improving our overseas bases in this way, we can provide meticulous support to customers who wish to move factories overseas or begin production abroad. In addition to plastic compounds, we will also engage in joint ventures and cross-industry collaborations while further strengthening and expanding our manufacturing bases and processing technologies in Japan and overseas, taking advantage of the Group's strengths in excellent development capabilities and unique technology.

Going forward, we will develop human resources with even more advanced expertise, provide products and services that contribute to resolving issues such as environmental conservation and safety, and continue to be a partner that provides creative solutions and to foster mutual growth with our customers.
