Tosoh Corporation

Although the Tosoh name may not be a household word, we are in fact a multinational corporation with a global reach. We are comprised of more than 10,000 people in more than 140 affiliates world wide, generating sales of roughly USD 6.6 billion annually. Headquartered in Tokyo, Tosoh is a comprehensive group of world-class companies located on almost every corner of the globe.

The Tosoh Group has a long list of accomplishments. We’re number one in Japan in the production of caustic soda and vinyl chloride monomer (VCM), with a production capacity of over one million tons a year for each. Our main plant is nothing less than a self-contained city, with its own electricity generating power plant and its own port and shipping facilities. Dedicated Tosoh ships and trucks guarantee a distribution line of the utmost efficiency and reliability.

On the global stage, Tosoh has the world’s largest production capacity of high-purity zirconia powders and electrolytic manganese dioxide (EMD), with around 20-percent of the market for alkaline dry cell batteries. We’re a leader in key commodity markets in the Asia Pacific region. And we’re a top worldwide producer of quartzware and sputtering targets.

Tosoh is a model of environmental responsibility, too. All Tosoh manufacturing sites in Japan have been awarded ISO 14001 certification for environmental management, and 100% of the products we create adhere to ISO 9000-series International Standards for quality assurance.

At Tosoh, we go to great lengths to meet the demands of the marketplace, and our clients appreciate the level of personalized service Tosoh is able to provide. We’d like for you to get to know more about the Tosoh Group of companies.
