COTTON RESEARCH CLUB
Developed by Toyoshima, this Japan-made basics brand focuses on premium blank garments crafted entirely within the country. Directed by Kazunori and Kanji Yamanobe – known for their work on A BATHING APE – the label was founded in 2025. Drawing inspiration from 1990s fabrics and silhouettes, every stage of production, from spinning to knitting to sewing, is completed in Japan. The brand aims to create universally appealing pieces that transcend age, gender, and culture.









Premium fabric born from traditional Wakayama loopwheel knitting
This 14oz loopwheel terry is woven on traditional machines in Wakayama, creating a substantial yet airy structure with a gentle loft. Cherished by vintage enthusiasts for its rarity and durability, it develops character as it is worn, aging gracefully over time.

The soft piled interior enhances comfort, making it suitable for long-season wear.



Enjoy a fabric that showcases the skill and craftsmanship of Japanese manufacturing.





The neckline is a gently opened crew style.



Flatlock stitching keeps seams smooth against the skin, reducing bulk and enhancing comfort.



The long vintage-inspired ribbing at the cuffs and hem uses a 1×1 knit for excellent stretch and recovery. It holds its shape, stays in place when sleeves are pushed up, and helps block out cold air.





Effortlessly versatile design
The silhouette offers relaxed room through the shoulders and body, making it easy to style. Clean and timeless, it pairs well both as a standalone piece or layered under outerwear, transitioning seamlessly from early autumn through spring.
