So I spend alot on jeans from japan, mainly to please my pedantic nature for historical accuracys and interesting weaves etc etc... obviously no one else notices but hey, I do.
This is a great forum for denim snobbery and what not. $600 jeans, buying 3 or 4 sizes too small etc

theres lots of interesting stuff, levi collectors, amerkaji culture ( when levi and lee et al expanded in the 70s they sold all their looms to japanese collectors, this is a crude explanation of why japanese denim is regarded as better, however "made in japan" is exploited and so this notion is not a hard and fast rule... ) soooo if your into your denim and collect vintage levi, if you want new jeans, the denim most like vintage levi or lee or wranglers would come from japan because thats where the looms have ended up.... and to be horribly generalistic I think japanese companys have a tendency to take quality and design to the nth degree.... which can make an interesting product, yknow?
Ironically Levi sue alot of japanese companys because they imitate ( in a purely romantic, homage sort of way ) levi styles like the red tab and arcuate.
Its ironic in so many ways, see even if your justification of buying from japan is for more vintage, true to history denim then the process is in opposition to this anyhow, its not like the cowboys of the 40s 50s and 60s would spend money buying jeans from japan, or compare fits, or worry about creases and whatnot...
There are the same subcultures with shoes....... churches, crockett and jones, all the italian makers, the american cordovan specialists alden.....
