paragraph_text: Japan
  
  Korea and Japan have had difficult relations since ancient times but also significant cultural exchange, with Korea acting as the gateway between East Asia and Japan. Contemporary perceptions of Japan are still largely defined by Japan's 35-year colonization of Korea in the 20th century, which is generally regarded in South Korea as having been very negative. There were no formal diplomatic ties between South Korea and Japan directly after independence at the end of World War II in 1945. South Korea and Japan eventually signed the Treaty on Basic Relations between Japan and the Republic of Korea in 1965 to establish diplomatic ties. Japan is today South Korea's third largest trading partner, with 12% ($46 billion) of exports in 2016.
  
  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. In 2009, in response to Prime Minister Junichiro Koizumi 's visits to the Yasukuni Shrine, President Roh Moo-hyun suspended all summit talks between South Korea and Japan in 2009. A summit between the nations' leaders was eventually held on February 9, 2018, during the Korean held Winter Olympics. South Korea asked the International Olympic Committee (IOC) to ban the Japanese Rising Sun Flag from the 2020 Summer Olympics in Tokyo, and the IOC said in a statement "sports stadiums should be free of any political demonstration. When concerns arise at games time we look at them on a case-by-case basis."
