Origin of Kouroka Lava

Where does Kouroka Lava come from?

Kouroka Lava is the volcanic rock mined from a new and remote active volcano island in the Fuji Volcanic Belt, the most famous volcanic belt in Japan. There are numerous volcanoes in this belt, while we choose the one which produces light, angular and quality lava rocks by several recent and perfect eruptions. Along with the inscription of Mt. Fuji as a World Heritage, only organizations which have obtained licenses from the government are eligible to collect lava rocks in the Fuji Volcanic Belt. This makes our lava rocks unique and exclusive.

We handle every step from mining, selection, washing, drying, packing to delivery of these natural gifts from the nature. This is how the quality of natural rocks to be distributed to the mass markets is ensured.
