D01

14.8oz Hard Denim
This is the "denim to grow into" that JAPAN BLUE JEANS has used since its launch.
The hard, durable feel is achieved by maximizing the number of yarns woven into the fabric, ensuring the firmness remains even after wear.
The dry touch and vintage-like texture are characteristic features of this fabric.
You can enjoy not only the visible changes but also how the fabric adapts and fits your body over time.

Aging Process
The treatment highlights contrasting tones and wear patterns, emphasizing the hard denim’s authentic, vintage look.
Through a final dyeing process, we've achieved a deep, realistic used look that cannot be replicated with ordinary dyeing methods.
Despite this intricate process, the fabric retains its firm structure, so you can look forward to even more unique fades over time.

M01

12.5oz Soft Denim
This denim strikes a balance between softness and durability.
By blending natural-colored cotton, we've recreated the "old-school blue" reminiscent of the time when synthetic indigo was first invented.
With its moderate thickness, it is comfortable to wear year-round, making it perfect for first-time denim wearers or women seeking soft, supple comfort.

Aging Process
The vivid indigo blue stands out in these jeans, with a look that mimics well-worn denim.
The natural texture of the cotton is expressed, and unique fades are recreated with the specialized techniques from Kojima.
The light and casual color pairs well with any top, making it versatile for a variety of outfits.
