Liancourt Rocks
The Korean government says that Usando was the Liancourt Rocks. Although it is impossible for one to survive at Liancourt Rocks without outside assistance, a distinction to be noted is that Usanguk refers to a state based on Ulleng-do, whereas Usando refers to an island. Japanese scholars argue that Usando refers to either Ulleung-do or Jukdo while Korean scholars argue that it refers to Liancourt Rocks.
