Blue refabric
Blue refabric / 13oz Semi-Wide Tapered 5P Jeans
Previously released as a JAPAN BLUE JEANS exclusive, this model is now offered under the Blue refabric line. Introducing the 13oz semi-wide tapered jeans.
By intentionally omitting the singeing process, this 13oz selvedge denim retains a raw, uneven texture with rich character.
The front is finished with a zip closure for ease of wear, and features details that will appeal to denim enthusiasts, including an engraved top button, an original vegetable-tanned leather patch, and red selvedge ID.
While offering a generous silhouette, it maintains a light feel and blends naturally into modern styling—a pair you can enjoy for years to come.

Blue refabric
Built on a concept of high-quality Japanese fabrics and a commitment to authentic craftsmanship. Originally produced for many years as a ROCOCO exclusive line of JAPAN BLUE JEANS, it relaunches in 2026 under the name “Blue refabric.” Production centers around partner factories of JAPAN BLUE JEANS. The name combines “Blue” — representing Japanese denim — with “Refabric,” a coined word blending Republic and Fabric. Inspired by the idea of a “Blue Republic,” the brand honors Japan’s textile heritage while creating garments that bring out the individuality of the wearer.
The fabric uses 13oz selvedge denim, woven on rare vintage shuttle looms still in operation today.
By intentionally skipping the singeing process, the surface retains natural fuzz and irregularity, giving the denim a raw, authentic texture.
Thoughtful detailing
The front features a zipper fly for easy wear, with a top button engraved with the Blue refabric logo.
A classic five-pocket design, simple and timeless.
The back is finished with an original Blue refabric leather patch, reflecting attention to detail throughout.
Rolling up the hem reveals the selvedge edge—a hallmark of shuttle loom weaving—adding a subtle accent to styling.
This edge was originally created to prevent fraying during the weaving process on vintage looms, and remains a detail highly regarded by denim enthusiasts.
A label on the inside signifies production at a partner factory of JAPAN BLUE JEANS.
A clean, tapered silhouette
A slightly lower rise with a roomy thigh, tapering sharply from the knee to the hem for a refined line.
The clean taper prevents heaviness, creating a balanced and polished look.
