Japan Blue X Momo, lends some of the "popularity" achieved by Momotaro, but destiquinses itself by, for instance other production environment (more industrial techniques versus the artisan hand crafts on the Momo's). Different dying mehtod. JBx Momo are sulphur dyed instead of using solely indigo. Other things that set JB apart from Momo is the use of different hardware and the lack of some details. Namely different hide on the patches, the lack of hidden rivets on the backpocket, no pink selvage outseam and "lower" quality cotton.
These partical details are the reason why JB is a lot cheaper than Momotaro, but then again JB is focussed on another market than the denimheads, namely the more gernreal buyer. JB is a brand estasblished to provide quality denim for a reasonable price, with the main goal to compete with other mid rier denim brands. It's a way for Japan Blue Group to get a greater share on te denim market.
So in short: Momotaro is a triple A brand, regarding quality, construction and a great focus on traditional methods an details regarding jeans production. Japan Blue is a brand more for the general jeans buyer/lover. Whilst still exeptional quality for the money, in an other legaue than Momotaro, but then again aimed at a totally different market.
Hopes this helps a bit...
[By the way, for those wondering why I dont post that often anymore. I think the new SF is shit, in terms of usabililty. Site is slow a hell and I don't find it easy to navigate. While that is just my personal opinion, I liked the old SF better]
