Is the Epson Japanese Kozo Paper Thin something similar to Moab's Moenkopi Kozo paper?
I'd have to see the spec - but at 110gm the Japanese Kozo Thin is less that 1/3 the weight. It was never a challenge to create a printable Kozo. The challenge was 34gm. Nothing on the market from Japan, Korea or China equals the Dmax, abrasion resistance, weight or texture of the Epson Kozo.
The recent review in the French magazine
Workflow which give 8.5/10 rating states 'L50 gamut of the Epson Kozo is very large for a paper of this kind. The equivalent in Awagami is very far behind. The D- Max is also very incredible for a paper in this category' It also listed Epson's Japanese Kozo paper Thin as a 'Favorite' and with a healthy list of 'Pros' the only 'Con' was that currently it is only available on Roll.
