45R is a Japanese brand renowned for its artisanal approach to denim, blending traditional craftsmanship with modern design.

If you love “real” denim, if you are a convinced denimhead, then this is definitely a brand you should check out. The 45R core line includes men’s as well as women’s denim.
Established in 1977, 45R emphasizes “monozukuri” – the Japanese philosophy of meticulous craftsmanship – resulting in garments that are both durable and comfortable.
Also interesting is that he label is built on slow fashion, quality that lasts and utilitarian designs that one can wear forever, and it goes about it all with the utmost dedication, turning the making of apparel into a craft.
45R’s denim is distinguished by its use of Ai indigo, a natural dye derived from Persicaria tinctoria, cultivated and fermented over a year-long process. This dye imparts a depth and complexity to the fabric that synthetic dyes cannot replicate.
The brand’s dedication to quality is evident in its use of vintage shuttle looms, producing denim with unique textures and character. Each piece is designed to age gracefully, telling a story through its wear and fade.
