CEO Message

In 1938, my grandfather, Mr. Jitsutaro Takimoto, was involved in the manufacture of soapstone clay. He founded and set up the company in 1940. Since then, we have been manufacturing soapstone clay by wet process.
In 1960, we introduced the Raymond Mill for the first time in Chugoku-Shikoku area and started production of soapstone clay by a dry process. In 1967, we started production of ultra-fine clay by installing a Ball Mill onsite.
Our business involves a wide range of crushing process from coarse grinding to fine grinding of soapstone clay, kaolin, talc, sericite and gofun (oyster shells powder) by using both wet and dry methods.
Recently, we have been carrying out a secondary process of powder mixing, classification, and surface treatment. Taking advantage of the unique characteristics of the wet process, we are crushing various minerals and stones, classification and chemical treatment. We are proud to say we are involved in the investigation and study of the intrinsic features of minerals for research and development.
