JAPAN BLUE JEANS
A denim brand from Kojima, Okayama—an area globally renowned as the birthplace of Japanese denim. Founded in 2011, Japan Blue Jeans was created to bring the quality of MADE IN JAPAN denim to the world. By combining silhouettes favored in Europe and the U.S. with uncompromising domestic craftsmanship, the brand proposes jeans with a fresh perspective.







A vintage feel that grows with wear
The fabric is made from soft cotton flannel—warm and comfortable without the itchiness often found in wool flannel.



Garment-dyed for depth of color, it fades gradually with wear and washing, developing a unique patina over time.



This piece is crafted from rare deadstock fabric, making it even more special as it will not be reproduced.





Design and durability in the details
The henley neck design, with its small cat-eye buttons, allows for versatile styling and adds a subtle touch of sophistication.



The sleeves are constructed from two panels for a more three-dimensional look, with loop buttons at the cuffs as a quiet accent.

Please note: as the buttons are small, they may slip from the loops—be sure to fasten securely during wear.



Durable flat-felled seams reinforce the construction, while intentional puckering enhances its vintage character. Piping at the cuffs and hem adds both durability and visual detail.





A sleeping shirt built for colder days
With its relaxed boxy silhouette, this sleeping shirt layers comfortably without losing shape.



Style it with a high-neck top peeking out at the collar or roll the sleeves for a more casual look. Versatile enough for chilly autumn days through the depths of winter, it’s a piece made to accompany the season.
