“ISHIKAWADAI Denim”—A new frontier in Japanese denim, shaped by the collaboration of skilled artisans across diverse disciplines.
Starting from the yarn itself, this premium denim is spun using a rare vintage spinning machine known as Ishikawadai. Then, it’s woven on the historic TOYODA GL-3 shuttle loom to reproduce the authentic texture of mid-century denim. The result is a 14oz fabric with exceptional hand feel that ages beautifully over time, developing deep and personal fades with wear.
ISHIKAWADAI Denim reflects BIG JOHN’s unwavering commitment to preserving tradition while reimagining it for the modern era—a genuine statement piece for denim purists and style enthusiasts alike.
Crafted using high-grade American cotton from Texas, this 14oz selvage denim is spun with irregular slub yarn to evoke a rich, textured surface that embodies the spirit of true vintage denim.
