Litter Reduction Plan
The 11th Regional Coast Guard Headquarters conducted a survey on what people whose lives are affected by the ocean think about the trash situation there to provide reference on measures to deal with the garbage. The survey was conducted via questionnaires answered by 95 fishing tackle and equipment stores on Okinawa Island.
The survey was conducted a second time via questionnaires to the island’s fishing industry associations. The results appear below.
