Japan Blue - J401 Low Tension Classic Fit 17oz

Where it’s made: Made in Japan
What it’s made from: 17oz selvedge denim, woven from American cotton
Fit description: Classic straight fit with deep rise, roomy thigh, and a gentle taper toward the hem

The J401 from Japan Blue is cut from a heavyweight 17oz selvedge denim, woven under low tension to create a fabric that is rough, rugged, and full of character. Using American cotton, the yarns are dyed in a deep, uneven indigo, giving the denim a richly textured surface and strong fading potential over time.

The silhouette takes inspiration from timeless straight-leg jeans of the mid-20th century: a deep rise, wide leg through the thigh and knee, and a subtle taper toward the hem. The result is a fit that feels relaxed and substantial, yet balanced and wearable with modern styling.
