Nihon Genryo was founded in 1939. At first, we were selling the glass material of gQuartz sandh by sieving know-how. In 1945, Nihon Genryo established brand- new company as a specialized gFilter Sand Mediah under the department of technology and the governments, GHQ. After that innovation, we focused on supplying filter media. We have supplied about 80% of whole part of water purification plants managed Japanese local governments, also became a pioneer of the construction media recycling. We experienced a lot at water works site, recycling used media construction. From that know-how, we developed gSaito Tankh series which are absolutely different from other tanks. Now our products apply any water conditions such as waste water, underground water etc. at Plants, Construction sites, and disaster areas so on as well as the water works. We still keep challenging for the worldwide water problems.
