SAMURAI "S0510XX-BOB AOKI TACHIKAGE" 15OZ BLACK AND BLUE REGULAR STRAIGHT JEANS

At first glance, this denim reads as pure black-on-black—stealthy, understated, and sharp. But look closer, wear it longer, and you’ll discover a depth that only reveals itself with time. Beneath the surface lies a carefully engineered interplay of color, texture, and craftsmanship that transforms this pair into something far beyond ordinary black denim.

Built from a rugged 15oz slub selvedge fabric, the character begins at the yarn level. A specially selected #6 slub yarn introduces natural irregularity—subtle thick-and-thin variations that give the denim a rich, tactile surface and dramatic vertical texture. The warp yarns undergo an intricate three-layer dyeing process: first rope-dyed in indigo, then overdyed with a black sulfide dye. As the denim ages, the outer black layer gradually fades, unveiling the indigo beneath. With continued wear, the indigo itself wears down to expose the natural white core of the cotton—just as in traditional jeans. The result is a uniquely dynamic fade progression: black to blue to white, evolving entirely through your lifestyle.

Complementing this transformation is a sulfur-dyed black weft that will soften and fade into smoky grey tones over time. Together, the warp and weft create a high-contrast aging effect that ensures no two pairs will ever look alike.

The selvedge ID features the brand’s signature silver lamé line—an elegant, almost metallic glint along the edge, reminiscent of a samurai blade catching light in the darkness.

Introducing the “Aoki Tachikage” series—named after the image of a sword flashing through the night. This edition comes in the 510 Regular Straight fit, cut with a mid rise, a roomy top block, and a clean straight leg that balances classic proportions with everyday versatility. It’s a silhouette designed to age as beautifully as the fabric itself.

Every detail reinforces the concept:

• Blue-painted metal buttons that echo the hidden indigo core

• A cobalt-blue coated button fly for subtle contrast

• Copper rivets for durability and heritage appeal

• Navy stitching that harmonizes with the underlying tones

• A family-crest patterned pocket lining for a hidden nod to tradition

• A supple goatskin leather patch that will develop its own patina

• Signature silver lamé selvedge

• 100% cotton construction

Though unsanforized, this pair has undergone a one-wash treatment to remove shrinkage, giving you the authentic texture of loomstate denim without the sizing guesswork.

Crafted in Japan with uncompromising attention to detail, the Aoki Tachikage 510 isn’t just black denim—it’s a slow-burning reveal. A fabric that evolves, deepens, and tells its story layer by layer, wear by wear.
