Quality management through a consistent system from excavation to product transportation!
Our company ensures a stable supply of high-quality crushed stone by consistently managing everything from raw material extraction to processing and logistics (supply systems). We employ the bench-cutting method, which allows for stable and safe excavation work without being affected by weather conditions. Additionally, raw material processing is conducted at each plant according to the type of crushed stone. Product inspections are carried out by dedicated technical staff based on JIS standards to ensure the quality of all products.

Company information
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.
