Nanyo Complex

Tosoh was established in 1935 in Yamaguchi prefecture, on a site which has been expanded and is called the Tosoh Nanyo Complex-a sprawling 3.7 million square meter facility, that is today one of Japan's largest fully integrated chemical manufacturing complexes.

The Complex boasts the largest in-house generating facility in Japan, capable of generating up to 829,000 kilowatts of electricity. Moreover, Tosoh's own port facility is capable of handling 48,000-ton cargo ship. Here at the complex, Tosoh initially began producing soda ash; later expanding its production line to include such products as caustic soda, chlorine and chlorine derivatives such as VCM, PVC, chloroprene rubber, and ethylene amines, among others.
