The Pure Blue Japan AI-13.5oz-019 embodies the essence of Japanese craftsmanship, combining traditional aizome (藍染め) natural indigo dyeing with a modern, versatile silhouette. Woven from 13.5 oz Japanese selvedge denim, this model represents a perfect balance between comfort, depth of color, and the artisanal spirit that defines Pure Blue Japan.
Each pair is dyed by hand in Tokushima, the birthplace of Japan’s indigo tradition. Local craftsmen, known as shokunin, use the sukumo fermentation method—a year-long process that transforms harvested indigo leaves into a deep, organic dye. Every yarn is hank-dyed multiple times, resulting in a rich, complex blue that develops a distinctive fade with wear. For this edition, both warp and weft yarns are crafted from 7-count cotton, with the weft first dyed beige before indigo immersion, creating a subtle, warm undertone unique to this denim.
The relaxed tapered fit offers room in the top block and thighs, narrowing gently toward the ankle for a modern, streamlined profile. Signature details include a 5-button fly, brass rivets, embossed iron buttons, and a blue selvedge ID. A deerskin leather patch and their signature "Shoai" leaf embroidery on the back pocket. One-washed for immediate comfort while preserving character, these jeans exemplify Pure Blue Japan's commitment to innovative textile development and traditional Japanese dyeing techniques – a perfect fusion of heritage craftsmanship and contemporary styling.
