Momotaro Jeans（桃太郎ジーンズ）: A Guide to TOKUNO BLUE

MOMOTARO JEANS（桃太郎ジーンズ） is a Japanese denim brand born in Kojima, Okayama. Its signature is TOKUNO BLUE: an unusually deep indigo shade designed to develop character through wear. For anyone curious about Japanese jeans, the brand offers a useful starting point—a connection between a textile-producing region, a distinctive fabric and the everyday pleasure of finding a good fit.

MOMOTARO JEANS at a glance

From Kojima to your wardrobe

Japan Blue identifies Kojima as the birthplace of MOMOTARO JEANS and traces the brand to 2006. Its account connects the label to Okayama’s textile traditions and the skills involved in dyeing, weaving and sewing. The company presents jeans as useful objects that record the wearer’s daily life through aging.

That idea makes the fabric part of the appeal: its place of origin, the decisions behind its construction and the way its appearance develops in an everyday wardrobe. Japan Blue also operates Japan Blue Jeans, a separate brand; the shared company name does not mean the two labels have identical products.

What is TOKUNO BLUE?

TOKUNO BLUE（特濃藍色）is the brand’s signature deep indigo. MOMOTARO JEANS attributes the shade to repeated dyeing and its accumulated dyeing expertise. Its official introduction emphasizes the color changes that emerge as the denim ages.

The brand also highlights Zimbabwe cotton and its background in textile manufacturing. These details help explain its approach, but specifications should still be checked for each garment. A brand story is not a substitute for the composition and finish on an individual product page.

Nor should “indigo” automatically be read as “natural indigo.” The official shop lists NATURAL INDIGO as a separate category. Choose by the actual fabric description rather than assuming that every dark-blue pair uses the same dye or process.

A current model: #100 STANDARD STRAIGHT 14.7oz

The official listing describes the #100 STANDARD STRAIGHT as a standard-width straight fit with moderate thigh room, a gentle taper below the knee and a slightly deep rise. The TOKUNO BLUE version uses rigid, unwashed denim. The manufacturer says the fabric is processed to reduce shrinkage, while still warning that washing can cause some shrinkage.

How to choose your first pair

Start with the silhouette you actually enjoy wearing. The current official shop groups jeans into Slim, Tapered, Straight and Wide fits. Those categories are a browsing aid; the measurements of the particular model are the more useful comparison.

Measure a pair you already like and compare the waist, thigh, rise, leg opening and inseam using the seller’s measuring method. Consider how you sit, walk and wear your shoes. A technically impressive fabric will get little use if the cut feels wrong.

If possible, try two silhouettes before deciding. For online purchases, settle sizing and return conditions before requesting alterations. The #100 product page states that hemmed items cannot be returned or exchanged.

Care: follow the garment’s instructions

For the #100 STANDARD STRAIGHT, the official guidance is to wash separately, avoid tumble drying and be aware of dye transfer. Do not interpret shrinkage-reducing treatment as a promise of zero shrinkage. Follow the instructions supplied with your particular garment.
