This is the slimmest unisex silhouette in the 45R denim collection. It is crafted from Futatabi 6.5, 45R’s original 14 oz denim, known for its firm texture and resilient body. Slowly woven on vintage shuttle looms from the 1950s, the fabric carries a density and depth that only time-intensive craftsmanship can achieve.

The Ai Indigo is built through repeated natural dyeing, creating a layered, profound blue. With wear, the color gradually softens, revealing a quiet, mist-like purple nuance while maintaining its composure. At the back waist, a natural indigo fabric patch features the discharge print “有 – Aru” (to exist), accompanied by carefully executed sashiko stitching that strengthens both structure and meaning.

Designed to evolve over time, the denim gains character through everyday wear, reflecting the enduring beauty of Ai dye and the thoughtful Japanese craftsmanship that defines 45R.

A Journey with Ai Denim

In September 2000, on the day we opened our New York store, we introduced Made-in-Japan denim dyed with natural Ai. For us, natural indigo does not begin in the dye vat. It begins in the fields—seeds planted in spring, leaves harvested in summer, then steamed, dried, and fermented into sukumo. In Tokushima, this process alone can take close to a year. Only after the indigo is carefully cultivated and the dye vat is built does the dyeing begin. The yarn is dipped and aired 20 to 30 times, oxidizing again and again, not simply coloring the thread but allowing the blue to grow. What drew us in was not just the color, but the layers of time held within it.

Story of 藍

While searching for a new possibility in denim, we encountered a rare workshop in Tokushima that carries out both indigo dyeing and weaving under one roof. Dyeing and weaving are usually separate crafts, yet here, naturally dyed yarn could be woven on a Japanese shuttle loom capable of producing true selvedge denim. Because indigo is alive, it changes with the day—sometimes vigorous, sometimes resting. Watching its condition, the artisans dye the yarn over two to three weeks until the color penetrates to the core. Around 2,200 warp threads are then aligned by hand and woven on a 1950s shuttle loom that produces only 30 meters a day. The clean white selvedge and the textured irregularity are marks of this loom, and even after repeated washing, the denim does not fade to white but deepens into a misty, purplish Japan Blue.
