Dat Kan Stone stimulates the sense of beauty



At Okurayama Studio, our highly skilled staff handles the entire process of quarrying, processing, and shaping our Daté Kan Stone, which is internationally renowned for its unique appearance.

We deliver the strength and beauty of Daté Kan Stone to the world in a variety of forms such as art pieces, construction, products and other projects while collaborating with successful creators in the fields of art, design, and architecture.


Daté Kan Stone is a kind of basalt/igneous rock known as two-pyroxene basaltic andesite that

was created around 20 million years ago. It has a dense grain and high specific gravity due to its

significant iron content, which makes it resistant to water and gives it a brilliant luster when polished.


The most important characteristic of the stone is that the surface appearance is always unique. In contrast , the interior of the stone exhibits a uniform charcoal color that gradually becomes more rust-colored with age. The wholly unique form and appearance of Daté Kan Stone continues to fascinate architects, artists, and designers both within Japan and abroad.
