Ulleungdo

Ulleungdo, the largest island in the East Sea, serves as a major fishery base as does Dokdo island.

A North Korean ship with five sailors on board was found adrift on Saturday in waters near Ulleungdo, an island off the northeast coast of South Korea, the Unification Ministry in the South said in a news release. Their ship was sinking when the South Korean Coast Guard came to their rescue, the statement said.
