TOKAI KOGYO Co,. Ltd.,Silica sand, Silica rock, minerals, Japan, AGC

| Izu Silica Rock | Domestic Silica Rock | Silica Sand for Road Aggregate Material |

"Izu Silica Rock" is come and produced from our "Izu Silica Rock Mines" at Ugusu, Nishiizu-cho, Kamo-gun, Shizuoka (West coast of Izu Peninsula)

Tokai Izu Silica Deposit, generated by hydrothermal process, is a very rare silica deposit in the world, in its formation and magnitude of the vast reserve. It is said that the mother rock of this deposit consists of volcanic rocks such as andesite,and is what metamorphosed under the action of volcanic boilling water,erupting gas,hot spring,etc.
