JAPAN BLUE JEANSA denim brand backed by a textile manufacturer based in Kojima, Okayama—one of the world’s most renowned denim-producing regions. Launched in 2011, the brand was created to share the quality of MADE IN JAPAN DENIM with the world. It introduces a new concept of jeans by combining globally appreciated silhouettes with the craftsmanship of Japanese-made fabrics.

The “just right” 13oz for year-round wearThe fabric is a 13oz natural denim with a beautifully uneven texture.
Not too heavy, not too light—just the right weight.
Layer it over a T-shirt in spring or fall, or over a sweatshirt or knit in cooler seasons—this jacket adapts to the seasons with ease.
The dry, slightly rough texture feels pleasant against the skin, making it a piece you'll want to wear all year round.
Soft fading that brings out natural characterThe jacket is finished with a soft fade treatment that gently lifts the color for a light, airy impression with depth.
Whiskering around the stitched areas adds a worn-in feel that brings effortless charm.
It avoids the stiffness and heaviness typical of denim, offering a gently broken-in look and feel that’s easy to wear.

Denim with a touch of Japanese traditionThe design is inspired by traditional Japanese haori and reimagined with the proportions of a Type 1 jacket.
By omitting front buttons, it’s designed to be thrown on effortlessly—perfect for light layering.

Thoughtful detailing, including side pockets and overall construction, reflects the care and precision of Japanese craftsmanship.

A perfect balance of ease and sharpnessThe base size is equivalent to a Type 1 jacket in size 40, with added room in the shoulders and body for a relaxed silhouette.
The slightly shorter length avoids bulkiness and gives it a neat, modern look. It also pairs well with voluminous inner layers, making it a versatile piece for transitional seasons.
