Other Features

Nippoh Chemicals was established in October 1948 to produce iodine from underground brine discovered in the Boso Peninsula.

The natural gas extracted with the brine is also effectively utilized for the production of hydrogen cyanide and its derivatives.

The advantage of the fact we are among the first companies to go into the field of fine chemicals with our unique technologies enable us to produce a great number of original products based on iodine, cyanogen, and bromide that won the trust of consumers.
