What is our Toyoura Silica Sand?

Now, starting with the imposition of tariffs by U.S. President Donald Trump, there has been an uproar over rice stockpiling in Japan due to a shortage of rice, and the failure of self-sufficiency in Japan has been clearly exposed like a comic of self-sufficiency.

In the world, the flow of distribution and trade is no longer flowing as before, and the tendency to put one's own country first is becoming more pronounced. As a result, the prices of various goods in Japan and abroad have soared, and the field of materials and substances has been affected in an uncertain and unstable situation in the future.

Our silica sand sells only this district natural domestic silica sand, and the silica sand is high purity, high quality, and not silica sand that can be produced anywhere

Because of its superiority, for 42 years from 1955 to 1997, the Japan industrial standard JISR5201 was set by the government, it played the role of a sand - JISR5201 - for measuring the strength of cement structures, which was indispensable for Japan to join the ranks of developed countries. Since the government changed to the international standard ISO in 1997, the role of the JIS standard of Toyoura silica sand has come to an end.

However, Toyoura silica sand does not end there, and in the field of geotechnical engineering, it is a silica sand used in tests according to JIS standards and the standards of the Geotechnical Society of Japan, and is considered to be an important silica sand in the study of liquefaction caused by earthquakes and landslides caused by severe rainfall. In particular, the liquefaction phenomenon has been elucidated in experiments using Toyoura silica sand, and has been incorporated into the liquefaction judgment of ground surveys

Along with Leighton Buzzard Sand in the United Kingdom and Ottawa Sand in the U.S., which are the world's leading high-quality silica sand, Toyoura silica sand is marked as Toyoura Sand, and is highly recognized, and is trusted and trusted by researchers, university professors, and scientists for its performance and properties, and is a silica sand that has received orders from all over the world.

In addition, at the request of the Japan Aerospace Exploration Agency (JAXA), it has been adopted as "earth sand" for experiments on the International Space Station (ISS).

Toyoura silica sand is not only used for industrial and research purposes, but also has a fine-grained appearance and feels like silk. It is also suitable for gardens, beaches, parks, school playgrounds, etc. We also sell B sand at a reasonable price. Please use B sand in such a place once, because the difference is that the grains are slightly larger. Both A and B sand are beautiful pale yellow sands. It is a high-quality silica sand that you can feel as the best sand even if you walk barefoot. Regardless of which purpose it is used for, silica sand combines beauty and functionality, and it is a sand that clearly distinguishes it from other silica sands. First of all, we would appreciate it if you could purchase even one bag and use our fine grained A sand.

In addition, customers who purchase more than 100 bags will be counted as a volume discount. If you buy a lot, we would like to start a service that will give you a lot of discounts, so we are looking forward to your purchase of a large number of bags.

Toyoura Silica Sand A - The No.1 Sand for Earthquake Research

Toyoura Silica Sand A has earned high acclaim from researchers, professors, and experts worldwide as the "premium silica sand" for research, experimentation, and testing. Especially in earthquake mechanism studies, it is often said that "if an experiment cannot be conducted with this sand, it cannot be done with any other sand." Such confidence in its performance underscores its exceptional reliability.
We encourage researchers and institutions to utilize Toyoura Silica Sand A in their experiments and studies aimed at mitigating large-scale disasters, including earthquake-related research and global national disaster investigations.

Why Choose Toyoura Silica Sand A?

Toyoura Silica Sand A stands at the forefront of research in earthquake disaster mitigation and natural disaster prediction. We invite you to incorporate it into your studies, helping to safeguard the future.
