Takeshima is wrong expression of Tokdo. 
 Tokdo is called '독도(Tokdo, Dokdo)' in Korea. 
 Japan claimed that Tokdo belonged to Japan 
 Historically, Korea has been taking full control over Tokdo for 1500 years except the JApanese Occupation Period(1910-1945). 
 and now Thousand of tourist every year are going to visit the Tokdo  for sightseeing. 
 Unfortunately, when a country dominate another, the main thing lost is the territory, such was the case of korea, when Korea was occupied by japan(1910-1945). 
 However After the Second World War, Korea, being liberated from Japan, recovered its territory, including Tokdo. In spite of that history, Japan claimed that Tokdo is Japan's hidden policy and of imperialistic expansion. 
 The problem is that those fabrications have been well documented, many Western accpt the distorted history .
