Premium Silica Sand
With a proud history spanning 70 years, our company has been providing high-quality silica sand to support the safety of cement structures. Initially recognized as the "Standard Sand" under Japan Industrial Standards (JIS) during the post-war reconstruction, and our product has kept the same standards after 1997, when the standards transitioned to meet international ISO standards. As times have changed, Toyoura Silica Sand has found applications across an even broader range of industries.
In particular, our silica sand has been recognized as the "premium silica sand" in earthquake research, contributing to the understanding of disaster mechanisms. We firmly believe that this exceptional material will continue to play a key role in future technological advancements and global challenges.
