Diatom Goods Manufacturer
Kanazawa-City, Ishikawa

soil - Created with Heritage Tech

Currently led by the 4th-generation proprietor Hiroichi Isurugi, ISURUGI CO., Ltd is a family business, which was established in Kanazawa in 1917 by Hanhichi Isurugi on the back of a family tradition of heritage plastering craftsmanship spanning much of the Edo-period (1603~1867).

Throughout the Showa period (1926~1989), ISURUGI was involved in large-scale national projects like the Osaka World Exhibition (1970), during which time company employees received many awards for outstanding craftsmanship. ISURUGI has also over the years lent its considerable skill base to the reconstruction of historical buildings such as the Kokuhou Zuiryuji Temple in Toyama Prefecture and Kanazawa Castle, not to mention modern buildings like Universal Studios Japan, Osaka Dome, and Kyoto Station. In addition to all this, ISURUGI set up a Plasterers’ Art Division in 2004 and started to become active in the field of design as well.

Certification mark

Since the quality of Diatomaceous Earth products made in Japan is generally better to compare to coarse products manufactured outside of Japan, a Japanese association relates to Diatomaceous Earth products has instituted a logo certification mark at 24th of Jan. 2018, to guarantee water absorption capacity as well as the content of Diatomaceous Earth.

This certification mark is only for qualified products from Japan. And all "soil" products sold in ALEXCIOUS are certified.


Earthen Bath Mat

Enjoy the sensation of moisture being sucked away
This amazing bath mat is really made of soil, or more specifically, Diatomaceous Earth (DE); a naturally occurring, highly absorbent material that retains water very efficiently, dries quickly, and has very effective deodorizing properties. Particularly good to use in environments where space is limited, the texture of the soil bath mat feels great on the soles of the feet. Available in three, 100% natural colors from Akita and Ishikawa prefectures, DE is harvested and molded with nothing added.

Diatomaceous Earth
DE is a remarkable, all-natural product made from tiny fossilized water plants. Millions of years ago in the Earth’s oceans, microscopic single-celled plants called Diatoms took minerals from the water and created protective shells for themselves. When they died, they drifted to the ocean floor to eventually become vast deposits. Now part of dry land, these deposits known as Diatomaceous Earth are harvested, milled, and ground into a talc-like powder, before being molded to create soil products.

Director's Comment:
"From our long history of 200 years of plastering, we developed a technology to process a product out of diatomaceous earth in a way that it cannot break anymore, using the knowledge of plasterer´s craftsmanship. It is remarkably difficult to combine the material with the products soft design and it took many trials until its final shape was completed. The quality of the finished product and much more related to the production process is a result of the craftman´s skills and his experience."
