In 1991, 45R was one of the few young Japanese brands crafting jeans from raw cotton, treating denim as an everyday essential that records the passage of time. The brand believes the character of denim is defined from the start—through cotton, yarn, dye, and weave—and continues to evolve with years of wear. Over three decades, 45R has refined its denim with new yarns, weaving techniques, shades, and fabrics, earning a strong reputation for quality.
