While in the USAF, a fellow airman had been aircrew on SA-16 Albatross with air sea rescue. As a favor when they picked up an aircrew at sea they would fly them back to their home base. I can no longer remember the the particular islands but it was known there were Japanese hold outs on several bases. He told me they fell into three types: first, those who knew the war was over but wouldn't go home in dishonor for losing, second , those who were not sure the war was over but were content as they were. Third were those who didn't care if the war was over, they were still at war. At one base, a gate had been installed near the kitchen in the perimeter fence so food could be put out for those living in the jungle/swamp. It was a tradition for new men and guests to sit on the back steps of the kitchen and watch for those to come and get food. No one ever saw them, yet food would gradually disappear during the night. Roy told me that it bothered him enough he couldn't watch through the night, knowing that they were watching him but he couldn't see them. At another base, he was told to be inside the fence at night because they recently had two Marines and two women killed by knife at night. They had gone in the bush in a jeep. Roy was in Air Sea rescue out of Okinawa from 1954 until Jun 1959. He told me those days three fourths of the island was off limits to US personnel and half was off limits to everyone. He had pictures he and a buddy took in the off limits area, souvenir hunting, of him at the mouth of a cave with a large mortar mounted on rails so it could be rolled in for reloading. The Japanese Self Defense Force was always clearing the off limits area of explosives and weapons. Roy said one year at the annual Japanese patriotic parade, they showed a 2man tank found cared for and operable.
