With the theme of developing environmentally friendly leather,
We manufacture a variety of new leathers
as well as conventional products.

COMMITMENT TO TANNING
ECO-ZEOLITE TANNINGⓇ
What is ECO-ZEOLITE TANNINGⓇ?
By using zeolite, a harmless mineral, as a tanning agent instead of traditional tanning materials (vegetable tannins and chromium), we can create BIO-DEG LEATHERⓇ*1, a leather that returns to the natural environment. When buried in soil under certain conditions, it decomposes in about six months and returns to the earth as nutrients.
This innovative natural leather material has won prizes in the New Leather Contest and has been exhibited at the Tokyo Leather Fair and Japan Leather Awards.
A new generation of sustainable leather that returns to the earth
We select and use biodegradable chemicals when making leather so that it can be returned to the soil. Decomposition has been confirmed through our own soil burial test, and over 40% decomposition was tested in 26 days by a European inspection agency*2.
If leather and leather products can be quickly decomposed in the soil when disposed of, they will not cause an increase in CO2 as would be the case when disposed of by incineration.
We aimed for a soft texture that is comparable to conventional chrome leather, but we do not use acrylic resin or polyurethane resin, which are often used in regular leather, as they are not decomposed by microorganisms.
In addition, the vegetable tannin used during re-tanning does not use tree bark or wood-derived materials (because wood takes a long time to regenerate), so the leather does not affect forest resources.
The finish is hand-crafted with an antique look that emphasizes the natural feel of natural materials. In recent years, various alternative leather materials have emerged, but our goal is to create a new generation of sustainable leather that cannot be replaced.
- 1.“BIO-DEG LEATHERⓇ” is not only biodegradable, but also increases the proportion of bio-based materials in the leather, aiming to become the ultimate bio-based material that stands above alternative leathers.
- 2. ISO 20136 is an international standard for the degradability of natural leather by microorganisms, newly established in 2020.

NSA Chrome Tanning
Innovative eco-friendly chrome tanning
The NSA chrome tanning method (Non Salt and Acid) is a cutting-edge chrome tanning technology that does not use salt or strong acids. We began working on it in 2022 and are conducting implementation tests on a production basis.
In the current pilot production, we are maintaining the quality and heat resistance of the leather as before.
- Amount of salt reduced by 70%
- 35% reduction in chrome tanning agent usage
- Amount of sulfuric acid: 100% reduction
- Amount of chromium oxide in wastewater reduced by more than 80%
We are achieving this by ensuring that chrome-tanned drainage water is transparent and reduces environmental impact.

Vegetable Tannin Tanning
Using a unique method, we can produce surprisingly soft vegetable tanned leather (tanned leather).
It features highly versatile soft leather.
Normally, tanned leather has the image of being hard, but our tanned leather has excellent softness and can be used for a wide range of purposes, including clothing leather.

Deer Leather
It is tanned from sika deer. We also use our own tanning technology to create a unique deerskin that stands out from regular deerskin.
It is the opposite of mass-produced leather, which requires all products to have the same uniform appearance.
