The character begins with the yarn. Spun on vintage Ishikawadai machinery, the yarn has a rustic irregularity that gives the denim depth, texture, and an honest rawness that modern uniform spinning cannot easily reproduce.

A tribute to the dawn of BIG JOHN and Japanese-made jeans. Rather than simply recreating vintage style, this series looks back to the starting point of Japan’s denim culture and brings that spirit into the present.

Depending on the model, the Ishikawadai series uses carefully selected cotton and denim weights to express a different kind of character. Some models feature 13oz denim made with African organic cotton, while others use a heavier 14oz denim with a distinct vintage-inspired texture.

The Ishikawadai series includes both selvedge and non-selvedge models. Each construction has its own purpose: selvedge models emphasize classic denim authenticity, while non-selvedge RG models reflect the spirit of the jeans BIG JOHN first produced in Japan
