We mine "PB Shinshu Shiga Stone (andesite)" from our own quarry and add value to it before selling it nationwide.

In addition, we offer services that cater to various needs, including domestic famous stones and rare stones.

As the best partner for landscapers, architects, and designers, our Stone Sommelier™ flexibly supports the creation of new landscapes™, from design to construction, based on a wealth of information on raw stones.
