Since the company’s 1926 establishment in Toyama City, Toyama Prefecture, Rin Kagaku Kogyo Co., Ltd., has been manufacturing and selling high-quality phosphorus products based on its innovative and reliable technologies.

 

Following its 1980 factory relocation to Imizu City (formerly Shinminato City), Rin Kagaku Kogyo Co., Ltd., became a wholly-owned subsidiary of Tosoh Corporation in 2006. Today, the company serves as a specialized phosphorus manufacturer that contributes to Tosoh’s Specialty Group business operations.

 

Envisioned in our corporate philosophy—“As the pioneer and expert in phosphorus manufacturing, we work to enrich people’s lives while upholding our values of honesty and commitment toward maintaining harmony with society”—we will strive to contribute to society by strengthening our technologies and creating new value in our phosphorus products.

 

We are making dedicated efforts toward environmental conservation and existing in harmony with our stakeholders while ensuring rigorous corporate governance and promotion of safety.


We look forward to your continued support.
