Tosoh Launches Full Operation of Its New Main Research Building at Nanyo Complex

Tokyo, Japan– On April 1, Tosoh launched the full-scale operation of its new main research building. The building is located in Shunan City, Yamaguchi Prefecture, at the Nanyo Complex, Tosoh’s primary manufacturing and research and development (R&D) facility. Tosoh constructed the main research building to strengthen its R&D for inorganic and organic specialty products.

Planning for the main structure and bench testing facility featured state-of-the-art equipment, and construction was completed in January 2020. It brings under one roof four R&D entities: the Inorganic Materials Research Laboratory, the Organic Materials Research Laboratory, the Technology Center, and the Tosoh Analysis and Research Center Co., Ltd., a Tosoh wholly owned subsidiary.

The new research building’s design is intended to bring together on each floor researchers working in different fields to encourage their active exchange of knowledge. It is hoped that the informational and technological synergies that result from fortifying cross-departmental collaboration will help accelerate the development of Tosoh’s specialty offerings, including zeolite, zirconia, eco-business products, and conductive materials. Through its continued innovation of new, proprietary products of value, Tosoh aims to contribute to the resolution of social issues.
