We use Studio D’Artisan’s original 13.5oz “Ishikawadai Denim.” This denim prioritizes texture and authentic historical reproduction over efficiency, showcasing our dedication to quality.

“Ishikawadai” refers to a ring spinning machine manufactured in 1953 by Ishikawa Seisakusho Co., Ltd., which is currently the oldest Japanese-made ring spinning machine still in operation. There are no manufacturing records, but it is believed to be the oldest operating spinning machine in Japan. Compared to modern ring spinning machines, its speed is about one-third, spinning only at a slow pace, resulting in low productivity. However, because it places less stress on the cotton, it preserves the fabric’s natural gentle texture, creating unique irregularities in the cotton’s appearance that computer processes cannot replicate— producing a slub effect reminiscent of hand-spun yarn.

The cotton used is “Deep South Cotton” grown in the Lower Rio Grande Valley, the southernmost part of Texas bordering Mexico. This cotton, cultivated vigorously on American soil, is well matured, with each fiber having substantial thickness, offering body and resilience. It is an ideal material for achieving a rough, dry texture.

The warp yarn is indigo dyed without compromising the unique texture of this cotton. We omit the usual yarn scouring process and intentionally introduce uneven dyeing, similar to vintage denim from that era. To faithfully reproduce 1953 denim, the entire process is carried out using low-tech methods.

Products crafted from “Ishikawadai Denim” spun on the Ishikawadai machine develop rich aging characteristics over time, breathing new life into them as next-generation vintage wear.
