About ONI Denim

ONI Denim is a Japanese denim label associated with veteran denim specialist Masao Oishi and a deliberately low-profile approach to production. Rather than focusing on elaborate branding, it builds its reputation around distinctive fabrics woven with irregular yarns and low-tension techniques. Its denim is particularly prized for its pronounced slub texture, rugged appearance, and rich fading potential, with its much-discussed Secret Denim becoming a standout among enthusiasts of Japanese selvedge jeans.
