We are dedicated to quality

Our Company has been producing and selling "Toyoura Standard Sand" (the "standard silica sand" (JIS Z 8801) under the former Japan Industrial Standards for the mortar-based flex and pressure cement strength testing in use until April 1997) since 1955, under strict quality control and the supervision of the Cement Association of Japan. From April 1997, the cement strength testing standard changed to the ISO standard, and the so-called "standard sand" also became the ISO standard sand. However, our Company has continued to make "Toyoura Standard Sand" (now known as"Toyoura Silica Sand" or "Toyoura Sand") to the same exacting standards as before. In addition, we continue to have our "Toyoura Standard Sand" tested by the laboratory of the Cement Association of Japan to the same strict former JIS standards.
