Liancourt Rocks dispute Japan. In 1954, Japan proposed a reference to the International Court of Justice, which South Korea rejected, believing that the Liancourt Rocks are irrefutably South Korean territories, and thus should not be dealt through diplomatic negotiations or judicial settlement between South Korea and Japan. There are conflicting interpretations about the historical state of sovereignty over the islets. Korean claims are partly based on references to a Korean island called "Usan-do" in various historical records, maps and encyclopedias such as the "Samguk Sagi", "Annals of the Joseon Dynasty", "Dongguk Yeoji Seungnam" (), and "Dongguk munheon bigo" (). According to the Korean
Liancourt Rocks dispute and thus Liancourt Rocks was still officially part of Korea as an ancient territory since 512. Korea presents evidence that Koreans living on Ulleungdo referred to Liancourt Rocks as Dokseom (or Dolseom; literally "rocky island") in speech and Dokdo 獨島 in writing as a phonetic transcription (음독 音讀, umdok; おんよみ 音読み on-yomi), while the name "Seokdo" 石島 ("rocky island") in the Ordinance was an instance of logographic translation (훈독, 訓讀, hundok; くんよみ 訓読み kun-yomi). Korea also states that Liancourt Rocks was effectively managed by seasonal fishermen and divers in recent times as a result of King Gojong's Ulleungdo Reclamation Program
