Iejima, previously romanized in English as Ie Shima, is an island in Okinawa Prefecture, Japan, lying a few kilometers off the Motobu Peninsula on Okinawa Island. The island measures 20 kilometres in circumference and covers 23 square kilometres. As of December 2012 the island had a population of 4,610. Ie Village, which covers the entire island, has a ferry connection with the town of Motobu on Okinawa Island.
Iejima is generally flat. The most notable geographic feature is a peak called Mount Gusuku at a height of 172 meters. The mountain resembles a volcano but is actually an erosion artifact. Alternately called "Peanut Island," for its general shape and peanut crop, or "Flower Island," for its abundant flora and more sizeable crop, Iejima draws tourists by ferry, especially during late April when the Ie Lily Festival begins. The Youth Excursion Village accommodates campers for 400 yen a person and includes access to a good beach. The YYY Resort and Hotel located just east of the ferry port is available for those who do not wish to camp.
