Fit Notes: Like many Samurai Jeans models, this one runs slightly small in the one-wash version. In general, we recommend selecting one size up from your usual. As always, please refer to the size chart to confirm the best fit. The denim is unsanforized but the jeans have been one-washed, so no additional shrinkage will occur.

The Samurai Jeans S511AX “AI Plus” 18oz Slim Tapered Jeans combine traditional Japanese craftsmanship with innovative denim development. Made in Japan, they feature a distinctive 18oz AI+ selvedge denim woven from a blend of standard indigo, natural indigo (ai-zome), and Samurai Cotton, all rope-dyed using a special technique that produces a deep, complex shade of indigo and a rugged, highly textured hand.

This model features Samurai’s popular slim tapered fit — trim in the top block with a clean taper through the leg — offering a modern silhouette without sacrificing comfort. Every detail highlights Samurai’s commitment to premium construction: a leather patch depicting an indigo-dyer artisan, silver-painted “taiko” drum buttons, copper coin-style rivets, AI+ printed pocket bags, and a special model-specific flasher.

The build quality is exceptional, with two-tone stitching in banana yellow and golden brown, applied with varied stitch counts, needle gauges, and widths across the garment. The S511AX “AI Plus” captures Samurai’s dedication to innovation, authenticity, and uncompromising craftsmanship in selvedge denim.
