Eight men who claim to be North Korean were found on a Japanese shore on Friday after their boat apparently ran aground. Officials in Japan reportedly do not believe that the men are defectors. They told authorities that they were fishing before the boat broke down. The boat reportedly bore a sign reading “Chongjin,” an eastern port city in North Korea. Tensions between Japan and the DPRK have been high recently as the hermit country’s leader Kim Jong Un continues to threaten missile strikes, some of which have traveled close to Japan.
