The Foundation of Denim: Big John's Enduring Heritage
Established in Kojima, Okayama in 1940, Big John is celebrated as the pioneer of the Japanese domestic denim industry. In 1965, the brand manufactured Japan's very first home-produced jeans, followed by the development of the historic KD-8 selvedge denim in 1973. The M104J Base model honors this rich history by focusing purely on essential form: an unpretentious five-pocket straight jean built on eight decades of technical textile mastery. Free from passing trends or extreme proportions, the Base serves as the primary building block of a well-curated workwear wardrobe.
Balanced Classic Straight Silhouette and Aging Potential
The M104J Base Classic Fit is engineered for those who appreciate natural balance in their denim. Cut with a comfortable, versatile rise and ample room across the hips and thighs, the silhouette falls straight from the knee down to a moderate leg opening. This proportion works effortlessly across footwear options-from casual sneakers and loafers to heavy Goodyear-welted service boots. Thanks to its factory one-wash treatment, the 14 oz rigid fabric is pre-shrunk and softened for comfortable daily use while keeping the natural texture, neppy grain, and deep indigo core intact. Over time, friction and movement will break down the surface indigo, producing authentic whiskers, honeycombs, and an individual patina unique to your routine. Whether tried on at our brick-and-mortar shop in Lund, Sweden, or ordered online across Europe, the M104J Base offers reliable Japanese denim craftsmanship designed to last for years.
