The Japanese earthen plaster

Since long ago, Japanese traditional houses have been built with local materials as wood, bamboo, straw and earth.
“Natural Raw Materials” are combined by “Craftsmanship”. The plasterers create walls and floors also cooking ranges with earth.
Plasterers can leave the materials still raw without chemical additives, so never break “Natural Circulation” and contribute to “Sustainable Society” and “Comfort of Residents”.

The power of earth as beneficial effects

Humidity regulation During humid seasons, the earthen walls can absorb moisture .
Conversely during dry seasons can release it in the air and so create less allergic symptoms condition.
De-formaldehyde The earthen walls and finishing of lime-plaster can absorb organic compounds such as Formaldehyde.
They can reduce the risk of contracting the Sick House Syndrome.
Deodorizing The earthen walls can reduce and absorb the life odor of pets, organic wastes, smoke and others.
They can contribute to purifying the air.
Sound-absorbing The grains of clay absorb and reduce the diffusion and the echo of daily life noises,
such as conversations, vacuuming, or the sound of footsteps.
Fire Protection The ingredients of earthen walls are basically clay minerals and sand. The earthen wall of both inorganic
and non-combustible material are excellent in fire protection. The plaster in particular offers a remarkable
fire-resistance, and is officially recorded as a non-combustible building material In Article 2,
paragraph 9 of the Standard Code of Japanese Architecture. Even in the case of fire emergency, there is
no risk of toxic gas being released from walls unlike synthetic materials.
Heat-storage Performance The earthen thick walls are harder to be heated up, but once heated, the walls can keep temperature
and can increase heating effect in winter.

Feeling of “Earth” for modern life

“TANZAKU” series are products manufactured by Sochikusya’s craftspersons with the traditional plastering
technique of earthen walls being disappearing in Japanese modern houses. The Tanzaku can introduce
the feeling of earth and reconsider that meanings.

Cooking stove

“COHETTUI” is developed by Sochikusya as a portable earth cooking range which you can take anywhere and
proposed to rediscover the Japanese traditional culture of using fire for cooking and also traditional techniques of polished finishing such as superlative Ootsu-Migaki, which are based on the original Japanese culture of earth plaster.
"CO" means "public", and "HETTUI" means "cooking stove".

Sochikusya

The “Sochikusya”, the Japanese earthen plasterer craftsmen group has responsibility
to inherit traditional techniques such as earthenwall, limeplaster and kamado transmitted from ancient Japan.
