COTTON RESEARCH CLUB
A Japanese blank-body brand produced by textile company Toyoshima, founded in 2025 with the concept of “Made in Japan.” Directed by Kazunori and Kanji Yamanobe — known for their work with A Bathing Ape — the brand draws inspiration from 1990s materials and silhouettes. Every step, from spinning to knitting and sewing, is done domestically. With a vision to create universal apparel that transcends age, race, and gender, COTTON RESEARCH CLUB pursues timeless, essential garments for the modern era.









Dry, Airy Comfort — Crafted with Intention
Made from 100% U.S.-grown cotton, this 6.6oz fabric delivers a distinct dry touch and substantial weight compared to standard T-shirts.

Despite its thickness, it feels light and smooth thanks to the use of open-end yarn, a spinning method that traps air within the fibers. This gives the fabric excellent moisture absorption and quick-drying properties for lasting comfort.



The crisp texture makes it ideal for warm weather, and its character deepens with each wear and wash — evolving into a piece that feels uniquely yours over time.





Thoughtful Details for Lasting Wear
The neckline features a classic crew design with a soft rib for easy wear.

Inside, a shoulder-to-neck binder reinforces the seams — a subtle but functional detail that reduces seam irregularities and adds durability around the neck and shoulders, ensuring this tee stands the test of time.





The sleeves and hem are finished with a single-needle stitch — a vintage detail often found in U.S.-made T-shirts from the mid-1990s.

This technique requires special machinery and skilled craftsmanship. While less efficient for mass production, it adds a subtle authenticity reminiscent of true vintage pieces.



The tubular knit body eliminates side seams, offering a smoother feel and unrestricted comfort for everyday wear.





The Everyday Tee, Elevated
With a relaxed yet balanced fit — neither too loose nor too slim — this T-shirt captures the essence of 1990s American vintage style. It’s a signature pattern that defines COTTON RESEARCH CLUB’s approach to modern basics.

Reflecting the brand’s belief in creating garments that transcend boundaries, this essential tee combines thoughtful craftsmanship with everyday wearability. A piece made to be worn, loved, and stocked — because even “ordinary” T-shirts deserve extraordinary care.
