Two packrafters were paddling the Class I+ section of the Tama River (western Tokyo) when one paddler snagged on submerged or partly-submerged river debris—metal wire or a loop. The paddler was in their 70s, and it is suspected that their paddle leash snagged the debris. It is not clear if they were in the boat or swimming when they came into contact with the debris. https://thingstolucat.com/2019/08/15/packraft-fatalities/
