Momotaro vs Japan Blue: Which Kojima Selvedge Powerhouse Should You Buy? (2026)

Q: Where are Momotaro and Japan Blue made?

Both are made in Kojima, in Okayama Prefecture, Japan, the historic birthplace of Japanese denim, using the Japan Blue Group's own rope dyeing and selvedge weaving.

Momotaro and Japan Blue are both made by the same Kojima parent company, Japan Blue Group, but Momotaro is the premium flagship line built around artisanal indigo and heavyweight fabrics ($200–$1,000+ USD), while Japan Blue is the accessible best-value line offering authentic Okayama selvedge at $130–$220 USD. If you want the absolute pinnacle of Kojima craftsmanship choose Momotaro; if you want genuine Japanese selvedge at the best price-to-quality ratio in denim, choose Japan Blue.

What Is the Difference Between Momotaro and Japan Blue?

Both brands come from the same house — the Japan Blue Group, founded by Collect Co. in Kojima, Okayama, the birthplace of Japanese denim. Momotaro Jeans launched in 2006 as the company's prestige label, named after the folk hero Momotaro and known for its signature pink "battle stripe" on the back pocket and its obsessive use of natural indigo and rope-dyed yarn. Japan Blue Jeans, launched a few years later, was created to bring that same Kojima weaving expertise to a wider audience at a lower price. At Japan-Denim.com, we think of them as two tiers of the same craftsmanship pyramid: Momotaro at the artisanal peak, Japan Blue as the broad, brilliant base.

The shared DNA means both use Zimbabwe and other long-staple cottons, weave on the same group's looms, and finish to a high standard. The differences show up in fabric weight options, indigo depth, hardware detailing, and price.

History & Background

Collect Co. began as a denim manufacturer and indigo dye house in Kojima before launching its own brands. Momotaro became internationally famous for its "Going to Battle" (GTB) line and limited runs of heavyweight 15.7oz and 18oz selvedge, plus ultra-premium natural-indigo pairs that can exceed $1,000 USD. Japan Blue Jeans focused on perfecting versatile 12.5–14.8oz selvedge in modern, wearable cuts — making it one of the most recommended entry points into Japanese denim for US and Canadian buyers. The two brands together have done as much as anyone to put Kojima selvedge on the global map.

Deep Dive: How They Actually Compare

Fabric is the clearest dividing line. Momotaro offers a wider range of heavyweight and specialty fabrics — including the famous 15.7oz GTB and rare natural-indigo batches — with deeper, more saturated indigo that fades with high contrast. Japan Blue concentrates on highly wearable mid-weights, typically 12.5oz to 14.8oz, that break in faster and suit everyday wear, which is ideal if this is your first raw denim.

Detailing also separates them. Momotaro adds signature touches like the pink battle stripe, hidden rivets, and custom-cast hardware, and its top-tier pairs are partly hand-finished. Japan Blue keeps detailing cleaner and more understated, which many buyers actually prefer for versatility. Both fade beautifully thanks to rope dyeing, but Momotaro's heavier, deeper-indigo fabrics generally reward patient wear with more dramatic results.

Fit philosophy differs slightly too. Japan Blue's modern slim and tapered cuts (like the J201 and J205) are tuned for contemporary Western tastes, while Momotaro spans classic straight workwear cuts through slim tapers. For most first-time buyers in the US and Canada, Japan Blue is the easier fit to land; for collectors chasing a grail fade, Momotaro is the destination.
