Japan Blue J514 14oz US Cotton Circle Loose Straight Black Jeans
The Japan Blue J514 Circle Loose Straight Black Jeans deliver a bold, heritage-inspired silhouette combined with modern Japanese pattern engineering. Crafted in Kojima, Japan, this model sits at the relaxed end of the Circle Jeans lineup, offering a wide, straight leg and elevated rise without sacrificing comfort or refinement.
The fabric is a newly developed 14oz Japanese selvedge denim, woven from 100% American cotton chosen for its strength and durability. Both the warp and weft yarns are sulfur-dyed black, creating a deep, uniform black tone with natural depth rather than a flat finish. Woven on vintage shuttle looms at higher tension, the denim feels compact and robust while maintaining a clean surface that ages gracefully with wear.
Like all models in the Circle series, the J514 features Japan Blue’s signature curved Circle waistband, engineered to follow the natural shape of the waist. This design significantly improves comfort and stability, especially in higher-rise, wider-leg silhouettes, reducing gaping and allowing the jeans to sit naturally on the body.
The J514 cut is a loose straight fit with a high rise and a wide leg opening that falls straight from the thigh to the hem. This silhouette channels classic workwear and vintage denim proportions, offering maximum comfort and a strong visual presence—ideal for pairing with boots, heavier footwear, or oversized tops. The denim is sanforized and one-washed, ensuring immediate wearability with no shrinkage.
Finishing details remain consistent with Japan Blue’s refined aesthetic: a black vegetable-tanned leather patch, custom engraved doughnut top button, gold metal zip fly, reinforced bar tacks, and durable cotton pocket bags. A peek-a-boo selvedge coin pocket and traditional red selvedge ID complete the design, grounding the jeans firmly in Japanese denim tradition.
Fit Notes: These jeans have a standard sizing. We recommend choosing your usual size. However, as always, we recommend checking the size chart first to find your perfect size. The fabric is sanforized, so there will be no shrinkage. The waist will experience the typical stretching seen in sanforized denim. Expect approximately 0.5 to 1 inch of stretching.
