 The LCE applied the name "Ongul" ("fishhook"), which is suggestive of the outline of the two islands when taken together.In 1957, the Japanese Antarctic Research Expedition (JARE) discovered that "Ongul" was actually two islands, separated by the Nakano-seto Strait, meaning "central strait".The name Ongul Island was retained for the largest island in the group, and the smaller island was given the name East Ongul Island.
