We're thrilled to introduce one of the rarest, most exclusive jeans we have ever seen. Each pair represents the pinnacle of craftsmanship, taking up to a year to produce in extremely limited quantities. Dyed with a premium Japanese Natural Indigo from the 'Polygonum tinctorium' plant. Following traditional Japanese "Aizome" method, the leaves are naturally fermented for over 100 days without any chemicals. Once mature, cotton yarns are hand-dipped into the Indigo once a day for 30 days. Creating the rich, vibrant Indigo hues "Aizome" is renowned for. Each unit undergoes a meticulous hand-dying process, making every jean a one-of-a-kind masterpiece.

Made from an extra-long staple, top-grade 13.5oz Zimbabwe Cotton grown especially indoors and hand-picked. This cotton is famous for its exceptional strength and softness that is similar to the finest Silk. The fabric is slowly woven on a first gen Toyoda GL9 shuttle loom. This vintage half-hand operated loom takes 5-7 days for a single pair of jeans. Because of this, each woven piece of fabric is only enough for 1 pair of jeans. Making each pair truly unique and one of a kind. The patch is a hand-woven Natural Indigo Sashiko with exclusive hand-embroidered design. It depicts a magical gourd meant to catch evil spirits and bring good luck and life. The yoke lining is a luxurious Natural Indigo Silk for exceptional strength and comfort. The custom top fly button and hand-hammered rivets are 925 Silver. The Selvedge ID is a special Natural Indigo thread. And the pocket bags are a GL9 Zimbabwe Cotton with limited "Aizome" Momotaro print and Momotaro tab.

Indigo is said to be the oldest dye used by humans worldwide. It was introduced to Japan around 1500 years ago. It was considered a noble color predominantly worn by courts and upper aristocrats during the Heian period. It was during the Edo period that indigo spread among the common people, and it is said that kimonos, work clothes, shop curtains, and even bedclothes were dyed in indigo. Being loved by the Japanese as an auspicious color, indigo was the symbolic color of Japan during the Meiji era, referred to as "Japan Blue" in other countries.

Indigo dyeing in Tokushima is said to have been introduced to Japan around 900 AD by the lord of Awa, Hachisuka, who recognized that the climate along the Yoshino River was suitable for indigo cultivation. The technique used in indigo dyeing in Tokushima is called "fermentation," with Awa indigo as a raw material. Since it cannot be dyed to a dark shade all at once, the process of dyeing, squeezing, and drying is repeated many times. It is said that the authentic color achieved through the Awa Shoai dyeing technique (hank dyeing) is obtained after washing with water about 30 times, during which the uneven color is washed off until a deep shade is achieved. Also, the unique scent with an insect repellent effect contributes to the atmosphere with seasonal transitions, giving the wearer peace of mind. In 1968, the "Awa Shoai dyeing technique" was designated as an intangible cultural property of Tokushima, and it is still preserved today.

These jeans are expensive, but the Japanese method of creating indigo dye is labor-intensive and incredibly time-consuming. Leaves are carefully gathered from the indigo plant and placed under thick straw mats for months on end. To ensure the leaves ferment properly, very specific conditions must be consistently maintained. Workers must perform daily maintenance to ensure that the leaves have proper airflow and stay at a temperature around 60 degrees Fahrenheit.

From picking the leaves to completion, the entire fermentation process takes approximately one full year. Finally, after months of patience and dedicated work, the final result is something that resembles dirt, but with a pungent, vinegary aroma. This product, known as "sukumo," serves as the basis for indigo dye.

Just as the indigo dyers of hundreds of years ago, the "Aizome" dyeing is a manual process, done on hands and knees while leaning over a large metal vat of inky blue indigo dye. The shade of blue after one dip will be very light, and the dipping process must be repeated multiple times to achieve darker colors.

Aizome process:

1. Grow Ai (藍 in Japanese, which is Natural indigo) leaves from March to July/August and cut the leaves in summer.
2. The cut leaves are fermented for 100 days to make Natural indigo dye.
3. Hank dye the yarns by very skilled craftsmen in Tokushima. Dyeing process: dip, squeeze, and wash the bunch of yarns – repeating this process about 12-14 times to achieve the dark color. Washing with water about 30 times in 30 days.

Momotaro's tight tapered fit is achieved through a snug fit around the waist, hips, and thighs, gradually tapering down to a narrower leg opening. This creates a sleek and modern silhouette that is versatile and complements various outfits.

Fit Notes: These jeans have a standard sizing. We recommend choosing your usual size. However, as always, we recommend checking the size chart first to find your perfect size. The fabric is sanforized, so shrinkage will be minimal. The waist will experience the typical stretching seen in sanforized denim. Expect approximately 0.5 to 1 inch of stretching.
