Oni is a mysterious label led by a true denim enthusiast who has devoted 60 years of his life to the craft. Always in pursuit of perfection, Oishi-san focuses solely on production. For this reason, there is no official website or Instagram page for the brand. It is also why the label is only distributed in a few select stores worldwide and exclusively through Flâneurs in France.
True to its reputation as a unique manufacturer, ONI presents a new feat with the "Asphalt Denim". Offered in a substantial 20oz weight, this fabric uses the same yarns as the famous "Secret Denim" but in a completely different way. Its snow-like appearance, caused by the inner cotton "neps" visible on the outside, is complemented by a highly pronounced slub texture. The combination of these two textures creates a unique fabric with depth and character.
The irregularities are an integral part of the fabric. To achieve this type of weave, the shuttle looms were set to extremely low tension. Oishi-san, the man behind ONI, allowed for these "imperfections," which appear as thicker cotton knots. Far from flaws, they do not compromise the jean’s quality or durability; instead, they enhance the beauty of the finished product and showcase the artisanal craftsmanship of this exceptional manufacturer.
Unlike the Secret Denim of similar weight, the Asphalt Denim is particularly rigid and coarse, which may surprise at first. Once worn, the low-tension weave quickly adapts to the body, providing comfort and flexibility. This initial stiffness also promises remarkable evolution over time. Its Dark Indigo base, paired with the brand’s characteristic brown reverse, will develop a patina unlike any other. With vertical fades, iridescent texture, and emphasized stress points, the Asphalt Denim will undoubtedly deliver one of the most striking fades.
The 288 features a "Regular Straight" fit with a high rise, deep rise, and a straight cut from thigh to leg opening, reminiscent of traditional straight cuts that shaped denim history. This model comes in a One Wash finish, washed once and sun-dried under the Japanese sun, which sets the waist and highlights the fabric’s unique texture.
Unlike most models usually offered by ONI, this one fits particularly small, and the stiffness of the fabric means we recommend going two sizes up from your usual size. Don’t worry about any initial tightness when putting them on — regular wear will naturally soften the denim and bring out its full comfort and character.
