The mysterious appearance of North Korean fishing boats on the Japanese coast has become a source of fear and speculation. These vessels, often found with deceased crew members, are frequently referred to as ghost ships. Investigations suggest that the North Korean government, driven by a desperate need for foreign currency, has pushed its fishing industry to extreme lengths. This has led to increased risks for fishermen, who are forced to venture further into dangerous waters to meet production quotas, often resulting in tragic accidents and the abandonment of these vessels.
