Longstanding issues such as Japanese war crimes against Korean civilians, the negationist re-writing of Japanese textbooks relating Japanese atrocities during World War II, the territorial disputes over the Liancourt Rocks, known in South Korea as "Dokdo" and in Japan as "Takeshima", and visits by Japanese politicians to the Yasukuni Shrine, honoring Japanese people (civilians and military) killed during the war continue to trouble Korean-Japanese relations. The Liancourt Rocks were the first Korean territories to be forcibly colonized by Japan in 1905. Although it was again returned to Korea along with the rest of its territory in 1951 with the signing of the Treaty of San Francisco, Japan does not recant on its claims that the Liancourt Rocks are Japanese territory.
