Big John was founded in 1940 in Kojima, Okayama, Japan by the Ozaki family as one of the earliest Japanese denim manufacturers — Big John was the first company in Japan to produce branded jeans (the iconic 'Big John' jean was first produced in 1965) and is widely credited with founding the entire Japanese-denim industry. The brand has been continuously operating from the same Kojima factory for over 85 years and is one of the longest-continuously-operating Japanese denim brands.
The Big John vocabulary settled around several specific products: the iconic Big John M-series selvedge-denim jean (the brand's defining 1965-pattern product, still in production with the original Kojima-loom selvedge construction), the Big John Rare jean variant (with deliberately-archival construction details), various heavyweight selvedge denim variants in shifting weights and treatments, hand-finished chambray and herringbone work-shirts, and a colour palette anchored to natural-indigo (the brand's defining colour — multiple depth variations), washed-cream, oxblood, ecru, plus the brand's recurring use of natural-undyed and traditional-Japanese-Kojima-denim-aesthetic colour combinations. Production is entirely Japanese at the original Kojima factory.
The brand is independent and family-controlled by the Ozaki family. Big John operates flagship retail in Kojima (the brand's home factory shop and museum — Kojima is widely considered the birthplace of Japanese denim, and Big John's factory is a defining anchor of the broader Kojima-denim-tourism cultural conversation), Tokyo (Daikanyama, Aoyama), Osaka, plus international wholesale through Self Edge (the long-running US Japanese-denim specialty retailer), Iron Heart UK, Cultizm, Blue Owl Workshop, Stag NY, Brut Clothing, and a curated set of heritage-menswear specialty retailers globally. The brand has been one of the founding-wave Japanese-denim manufacturers.
