“ISHIKAWADAI Denim” is the result of an ambitious collaboration across multiple Japanese crafts — a pursuit of new possibilities in denim through time-honored techniques.
From raw materials to finishing, every step has been carefully considered. The fabric is spun using a rare vintage spinning machine known as Ishikawadai, and woven on a traditional TOYODA GL-3 shuttle loom to reproduce the authentic texture of early-era denim. The result is a 14oz fabric with a satisfying hand feel that will develop a rich, beautiful fade over time with wear.
ISHIKAWADAI Denim is a premium creation that bridges tradition and innovation — a true expression of BIG JOHN’s passion for authentic, heritage-driven craftsmanship.
Made from high-quality American cotton (Texas origin), this 14oz selvage denim is spun with irregular slub yarn to bring out the deep character and classic expression that only true denim can deliver.
