Cotton: japanese vs other cotton

It's the denim and how it's made, did you do a search? Do a search.

Here is a link:

In most (all?) cases the cotton isn't Japanese. The companies are using cotton from Zimbabwe, Texas, etc...

I don't think that I have ever heard of Japanese cotton being in demand...

It's more like certain features of said c otton versus the 'quality.' Single crop, short fiber, etc.

I wonder if natural woven selvedge denim can compete with Japanese selvedge denim

 

Here's an article about Sea Island Cotton, a well known top of the line material. Long staple cotton is softer, the texture gives it a nicer feel on the hand. Zimbabwean and Egyptian cotton also has a long staple. Varying qualities are often linked to growing conditions & environment. Obviously a noticeably softer fabric that can only be batched in small quantities is going to cost a ton of money and those costs multiply through production, wholesale, and retail.
