Commitment to Materials

Staying true to our expertise in shirt-making, we chose cotton as the key material. While synthetic fabrics dominate the market, our latest design is crafted from high-twist cotton. This unique yarn offers a smooth, non-cling feel, combined with cotton’s natural softness for year-round comfort. From fabric production to stitching, everything is original and exclusively MADE IN JAPAN.
