Jeju Province, officially Jeju Special Self-Governing Province, is the southernmost province of South Korea, consisting of eight inhabited and 55 uninhabited islands, including Mara Island, Udo Island, the Chuja Archipelago, and the country's largest island, Jeju Island. The province is located in the Korea Strait, with the Korean Peninsula to the northwest, Japan to the east, and China to the west. The province has two cities: the capital Jeju City, on the northern half of the island and Seogwipo, on the southern half of the island. The island is home to the shield volcano Hallasan, the highest point in South Korea. Jeju and Korean are the official languages of the province, and the vast majority of residents are bilingual.
Hallasan (Korean: 한라산) is a shield volcano on Jeju Island in South Korea. Its summit, at 1,947 m (6,388 ft), is the highest point in the country. The area around the mountain is a designated national park, named Hallasan National Park. Hallasan is commonly considered to be one of the three main mountains of South Korea, along with Jirisan and Seoraksan.
Jeju City is the capital of the Jeju Province in South Korea and the largest city on Jeju Island. The city is served by Jeju International Airport.
A number of Korean dialects are spoken on the Korean Peninsula. The peninsula is very mountainous and each dialect's "territory" corresponds closely to the natural boundaries between different geographical regions of Korea. Most of the dialects are named for one of the traditional Eight Provinces of Korea. Two are sufficiently distinct from the others to be considered separate languages, the Jeju and the Yukjin languages.
The Jeju uprising, known in South Korea as the Jeju April 3 incident, was an uprising on Jeju Island from April 1948 to May 1949. A year prior to its start, residents of Jeju had begun protesting elections scheduled by the United Nations Temporary Commission on Korea (UNTCOK) to be held in the United States-occupied half of Korea, which they believed would entrench the division of the country. A general strike was later organised by the Workers' Party of South Korea (WPSK) from February to March 1948. The WPSK launched an insurgency in April 1948, attacking police and Northwest Youth League members stationed on Jeju who had been mobilized to suppress the protests by force. The First Republic of Korea under President Syngman Rhee escalated the suppression of the uprising from August 1948, declaring martial law in November and beginning an "eradication campaign" against rebel forces in the rural areas of Jeju in March 1949, defeating them within two months. Many rebel veterans and suspected sympathizers were later killed upon the outbreak of the Korean War in June 1950, and the existence of the Jeju uprising was officially censored and repressed in South Korea for several decades.
Seogwipo is the second-largest city on Jeju Island, settled on a rocky volcanic coastline in the southern part of Jeju Province, South Korea. In July 2006, Seogwipo's boundaries were expanded to include the entire southern half of Jeju island. A UNESCO World Heritage Site and 2002 FIFA World Cup host, it had a population of 192,566 as of the end of February, 2024.
Jeju Island is South Korea's largest island, covering an area of 1,833.2 km2 (707.8 sq mi), which is 1.83% of the total area of the country. Alongside outlying islands, it is part of Jeju Province.
Korea comprises the Korean Peninsula and 3,960 nearby islands. The peninsula is located in Northeast Asia, between China and Japan. To the northwest, the Amnok River separates Korea from China and to the northeast, the Duman River separates Korea from China and Russia. The Yellow Sea lies to the west, the East China Sea and Korea Strait to the south, and the Korean East Sea to the east. Notable islands include Jeju Island (Jejudo), Ulleung Island (Ulleungdo), and the Liancourt Rocks.
Jeju, often called Jejueo or Jejuan in English-language scholarship, is a Koreanic language originally from Jeju Island, South Korea. It is not mutually intelligible with mainland Korean dialects. While it was historically considered a divergent Jeju dialect of the Korean language, it is increasingly referred to as a separate language in its own right. It is declining in usage and was classified by UNESCO in 2010 as critically endangered, the highest level of language endangerment possible. Revitalization efforts are ongoing.
The Jeju Volcanic Island and Lava Tubes is a World Heritage Site in South Korea. It was inscribed as one of the UNESCO World Heritage Sites in 2007 because of the Geomunoreum Lava Tube System and the exhibition of diverse and accessible volcanic features which are considered to demonstrate a distinctive and valuable contribution to the understanding of global volcanism.
The Jeju striped field mouse is a field mouse found only on Jejudo, an island in the northern East China Sea off the southwestern coast of South Korea. It was originally described in 1965 as a subspecies of Apodemus agrarius. However, a 1992 study of mitochondrial DNA found that it was in fact a separate species.
Hynobius quelpaertensis, the Jeju salamander, also spelled Cheju salamander, is a species of salamander found on various islands and peninsulas off the southwestern coast of the Korean Peninsula, including Jindo, Geojedo, Jejudo, and Namhae. It inhabits moist mountain forests.
Mankyua is a monotypic genus and fern in the Ophioglossales. Its only species, M. chejuense, grows only on Jeju Island of South Korea. While this plant is clearly ophioglossoid in the broad sense, its precise cladistic position is uncertain. It has a fused sporangial structure similar to Ophioglossum, but a vegetative structure, with palmately-radiating pinnae, reminiscent of Helminthostachys. It may be a basal offshoot of the ophioglossoid clade sensu stricto.
The Jeju Dog (Korean: 제주개) is a breed of dog that was brought back from the edge of extinction in 1986, when only three of them were found on the entire island of Jeju in South Korea. Since then, an aggressive campaign of breeding has yielded a current population of close to 300. However, the 'pure bred' Jeju Dog population is only estimated to be at about 69 as of September 2010.
The Jeju horse is a horse breed native to the Jeju Island in South Korea. There is a diverse array of types, each differently identified depending on their coat color. Jeju horses mature well in harsh conditions due to their strength and fitness. With an outstanding tolerance of low temperatures, they have been mostly pastured without the need for horse blankets or stables.
The Chuja Islands are a group of 42 islands in the Jeju Strait, about halfway between Jejudo and the southern coast of Jeollanamdo. Only four islands are inhabited: Sangchuja, which is connected by a bridge to Hachuja, the largest by area; Hoengang; and Chupo. The Chuja Islands are administered by Jeju City. As of December 31, 2019, the population is 1,733, based on the number of citizen registrations.
The wildlife of South Korea includes 8,271 plant species, 18,117 animal species and 3,528 species of fungi and others. 30,000 species are known to exist in South Korea, but it is estimated that there are more than 100,000 species.
The Jeju people or Jejuans, also known as Cheju people or Chejuan, are an ethnic group native to Jeju Island, which is geographically located in the East China Sea. Administratively, they live in Jeju Province, an autonomous self-governing province of South Korea.
