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 valuable for their pure white crystalline quality, at each of our factory locations. The high quality and abundance of these resources are our greatest pride and our most significant asset. Furthermore, our enthusiastic research and technology team has created the "heavy calcium carbonate" industry, which can be said to have originated from "light calcium carbonate," starting with the development of "ultrafine NS." Following this, we have introduced various new products, including surface treatment products such as the "Nobelite-NCC" series, granulated products like the "Carpet" series, and submicron products comparable to colloidal calcium carbonate, such as the "Nitrex" series. 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.
