Thank you for looking. This was stored in my home warehouse. After looking into it, it appears to be a type of fishing net called "sashiami". I am not familiar with this type of fishing gear, so please be aware of this. When I spread it out, it was about 1 meter wide and approximately 15 meters long (this is an estimate). I did not see any tears in the net upon a quick inspection, but I cannot guarantee it.
