It mostly goes like this: in Japan and Korea nearly everyone lives in apartments. Therefore they have no garage, nor a backyard. Thus they have no place to keep a fishing boat. Very few guys actually own sportfishing boats. So what's an angler to do when he wants to get offshore? He pays a commercial fishing boat captain to take him offshore to some remote rocks where the fishing is good. The captain drops them off and comes back later. Some are small uninhabited islands, others are tiny patches of rock just barely sticking out of the sea. Sometimes the tide comes up and those guys get washed away. Or the commercial fishing boat captain gets drunk back at the village, passes out and forgets to pick them up at the designated time and they die from dehydration, hypothermia, drowning, or sharks."
