Description

With the J204 Tapered Fit, Japan Blue Jeans offers a lighter and more breathable interpretation within its CIRCLE line, combining ergonomic construction with Japanese selvedge denim woven from African cotton. Known for its smooth, consistent fibre and natural softness, this cotton produces a fabric that is comfortable, breathable, and capable of developing a refined fade over time.

The 12.5oz fabric sits in a lighter weight category compared to Japan Blue’s standard denims, offering an excellent balance between comfort and structure. Thanks to its one wash treatment, the fabric is stabilized and slightly softened from the first wear while retaining its authentic raw denim character.

A defining feature of the CIRCLE line is its curved waistband, designed to naturally follow the shape of the hips. This construction helps eliminate gaps at the back of the waist and significantly improves comfort when sitting, while also providing better overall stability. It is a core element of Japan Blue’s ergonomic approach in this collection.

The model features a Tapered Fit, a modern and versatile silhouette defined by a comfortable thigh and a gradually tapered leg from the knee down. This controlled volume creates a clean, contemporary look without excess width, while maintaining excellent freedom of movement and everyday wearability.

Finishing details reflect the attention to craftsmanship: red selvedge ID, copper rivets and button, YKK zip fly, reinforced stitching, and signature blue inner leg stitching. Each element is designed to balance durability, functionality, and understated aesthetics.

Made in Kojima, Japan, this model perfectly embodies Japan Blue Jeans’ philosophy: offering authentic, durable, and modern denim designed for everyday wear while developing strong character over time.
