Maybe *via* USA, but origin of repros/copies more likely to be China.
Zstore, CAL :
These wheels were reproduced using the original Nissan mold, then wrapped in black composite material with the texture of leather to look just like the original competition units.

Another US distributor advertising shares the same clues :
This limited replica is made from the original production molds. These are not leather-wrapped like the first generation wheels; rather, they are the more common and popular urethane type.
Caution: There are small rough spots on the rear surface of the wheel. These are from the vacuum injection process and are present even on genuine Nissan examples
Since it is completely normal for this item, we cannot accept any returns of this item citing this issue

So, if these repros/copies originated in China (as you infer but do you have facts or just another supposition ?), then some entrepreneur must have passed them the mold from Japan - no ?
Or the publicity is woefully economical with the truth and these were knocked off a mold made from a genuine article, again...perhaps, from a Japanese entrepreneur ?
Hardly surprising to see repros/copies or as these might be more aptly termed, 'in the style of', when the genuine articles command such astronomical prices and the rest of the world would like to share the same look !
I'd be curious to know, please, which and when the genuine wheels were leather and vacuum-injected composite material - were they sold in parallel or one after the other ?
