日東粉化商事 Company Profile

We are a comprehensive manufacturer of heavy calcium carbonate products, proudly leading the industry in the mining, production, and processing of calcium carbonate (CaCO3) both domestically and internationally.

Since its establishment, our company has focused on the mining, manufacturing, processing, and sales of calcium carbonate (CaCO3). In Japan, where resources are scarce, we own limestone mines, particularly precious pure white crystalline limestone, at each of our factory locations. The high quality and reserves of this resource are our greatest pride and our most significant asset. Furthermore, our enthusiastic research and technology team has created "superfine NS," which can be said to have established the "heavy calcium carbonate" industry in contrast to "light calcium carbonate." Following this, we have developed various new products, including surface treatment products such as the "Nobelite-NCC" series, granulated products like the "Carpet" series, and the "Nitrex" series, which rivals colloidal calcium carbonate in the submicron range. As a comprehensive manufacturer of calcium carbonate, we consistently lead the industry as a top manufacturer, boasting excellence in quality, technology, and quantity both domestically and internationally.
