Liancourt Rocks are a small group of rocky islets in the Sea of Japan (East Sea) administered by the Republic of Korea and often referred to as Dokdo in Korean or Takeshima in Japanese. The feature comprises two main islets and multiple smaller rocks and is the subject of international territorial dispute.

The islets have long been referenced in regional charts and accounts; in modern times they have been under South Korean administration with a permanent Coast Guard or police presence established in the mid-20th century. Control and sovereignty over the rocks remain disputed between Korea and Japan, and the islands have been subject to political and diplomatic actions since the 20th century.

The rocks sit offshore in the East Sea and are administered as part of North Gyeongsang Province, Republic of Korea. The nearest Korean administrative centre is Ulleung County, which serves as the usual departure point for boat visits to the islets.

  • Visiting conditions: Landing is weather-dependent and limited; many visitors view the islands from sightseeing boats rather than disembarking.
  • Administration: The islets are administered as part of Ulleung County, North Gyeongsang Province, Republic of Korea.

What to See #

  • Main islets: Consists of two main islets, commonly called Dongdo (East Islet) and Seodo (West Islet), plus numerous smaller rock outcrops; the two principal islets are the only areas suitable for landings and facilities.
  • Facilities and occupancy: A small South Korean Coast Guard/police detachment, a lighthouse and a basic pier occupy the islands and are the primary permanent installations on the rocks.
