Pure Blue Japan is renowned for its Japanese selvedge jeans, crafted using raw denim woven on a single vintage low-tension shuttle loom. This unique method produces slubby, textured fabric with a distinctive, uneven weave—hallmarks of authentic Japanese denim. Made in the historic mills of Okayama, each pair is dyed with natural indigo and finished with PBJ’s signature indigo leaf on the back pocket. Known for high quality denim and deep character, these jeans age beautifully over time, becoming a true reflection of the wearer and a benchmark for artisanal craftsmanship.

Pure Blue Japan (DNP-019-IDSM) 16oz Double Indigo Nep Denim Relaxed Tapered
Sumi-dyeing is a rare Japanese dyeing technique that uses traditional sumi ink to create smoky black tones on indigo denim. Made from fine pine soot and natural glue, the ink is ground with water before being applied to the weft yarns.
For its Double Nep denim, Pure Blue Japan selected irregular yarns with a unique nep texture—tiny white flecks and fuzzy cotton knots that create a snowy, three-dimensional appearance. Combined with Pure Blue Japan’s original 16oz weave, this denim offers exceptional texture, depth, and character, while developing beautiful fades with wear over time.

Pure Blue Japan (GRE-003) 14oz Greencast Indigo Regular Straight
Green Cast Indigo is a new denim that combines brightness and depth.
The subtle effect of the blended green dye creates a vibrant yet subdued hue. This allows it to blend well with other colors and be easily paired with a variety of items.
To achieve this unique color, we went through repeated trial and error, carefully adjusting the green dye formulation and the concentration of indigo. We hope you enjoy this original color.
The classic XX series' distinctive texture is still intact. The rope-dyed yarn also allows for a pleasing fade.
The GRE-019 silhouette features a relaxed tapered fit with a comfortable fit around the thighs.
