Jeju-do

Jeju Province, officially Jeju Special Self-Governing Province, is one of the nine provinces of South Korea. The province comprises Jeju Island, formerly transliterated as Cheju or Cheju Do, the country's largest island. It was previously known as Quelpart to Europeans and during the Japanese occupation as Saishū. The island lies in the Korea Strait, southwest of South Jeolla Province, of which it was a part of before it became a separate province in 1946. Its capital is Jeju City and it is home to South Korea's tallest mountain, Mt. Halla.
