BLUE
The origins of JAPAN BLUE that captivated the world
In the late 19th century, a British scientist who was impressed by indigo-dyed clothing named the Japanese blue "JAPAN BLUE." We are passionate about inheriting this traditional "blue" and creating a diverse world of "blue" with denim. We put this feeling into the name "Japan Blue Jeans" and offer one-of-a-kind jeans that inherit Japanese culture and aesthetic sense.
DENIM
Fabric made to give you the look of authentic denim and a light, comfortable fit
Based on the belief that "making jeans is making fabric," we use our unique spinning technology to create a yarn quality that is both strong and flexible.
Our passion for fabric and unique craftsmanship creates an innovative denim experience.
DISTRESSING & WASHING
Processing techniques that create unique characteristics in the fabric and create changes over time
Kojima's traditional processing techniques are not just distressed. They bring out the best in the characteristics of the fabric and create a realistic aging effect. From the moment you get your hands on them, you can enjoy the inherent charm of denim, as if it has been worn for many years.
