八溝マテリアル Company Profile

We produce high-quality crushed stone based on the hard sandstone of the Hakko Mountains!

Our factory is located in a picturesque area of the Yamizo mountain range, spanning the three prefectures of Fukushima, Ibaraki, and Tochigi. The raw stones (hard sandstone) extracted from this region have a hard texture with minimal binding material, making them suitable for processing into very high-quality crushed stone. While giving due consideration to the preservation of this rich natural environment, we produce excellent foundational materials from high-quality and valuable natural resources.
