Founded in 1928<br>Iwasa's continued commitment to manufacturing
- high quality
- High functionality
You want to use it for a long time, so choose something of high quality that you can rest assured about.
All materials produced in Japan
Not only is it made entirely domestically and woven to reliable quality standards, but the fabric is also surface treated to make it water repellent during dyeing, so you can use it with confidence.
Japanese craftsmen carefully create each item one by one.
The biggest appeal of Japanese-made products is, of course, the "careful finish that reflects the Japanese aesthetic sense." Craftsmen painstakingly create this in a beautiful, well-organized space. We deliver products with a warmth that cannot be found in mass-produced products and a sense of cleanliness that can only be found in domestic products.
Iwasa uses Mitsubishi Chemical's Soalon.
“Soalon” is a high-quality triacetate fiber that is environmentally friendly and has high scarcity value.
"Soalon" is an eco-material certified by the Biomass Mark. Only trees that are sustainably managed are used to enhance the natural regenerative power of forests.
Triacetate is a semi-synthetic fiber that combines the benefits of plant-based raw materials made from natural pulp with the benefits of synthetic fibers made from chemical materials. The product name is Soalon. Soalon, the only product in the world manufactured exclusively by Mitsubishi Chemical, has received high praise all over the world.
Triacetate fibers have a silk-like luster and smooth feel, and are dyed a deep black, making them a high-quality material that is often used in expensive black formal fabrics.
