Japan–South Korea relations
Japan–South Korea relations (; ) refers to the diplomatic relations between Japan and the Republic of Korea. As both nations are separated by the Sea of Japan and the Korea Strait, Korean-Japanese interactions have existed since ancient times; the southern portion of the Korean Peninsula acted as a closest entryway for Japan to engage in economic trade and cultural exchange to and from mainland Asia. By 1910, Korea would become a colony of Japan until 1945. Shortly after gaining independence, Korea was divided into two states. During the Korean War, Japan took part in aiding South Korea by providing military supplies to US and UN forces against the communist-led North Korea. Japan and South Korea formally established diplomatic relations in December 1965, under the Treaty on Basic Relations between Japan and the Republic of Korea, with Japan recognizing South Korea as the only legitimate government in the Korean peninsula. Japan and South Korea share many cultural, economic, and military ties. Their economies are respectively the second and fourth largest in Asia, and they are both military allies of the United States. Relations, however, are greatly complicated by a number of issues, including territorial claims on Liancourt Rocks and conflicting views on mutual history. According to a 2014 BBC World Service poll, 13% of Japanese view South Korea's influence positively, with 37% expressing a negative view, while 15% of South Koreans view Japanese influence positively, with 79% expressing negatively, making South Korea, after China, the country with the second most negative perception of Japan in the world.

Under the leaderships of South Korean president, Yoon Suk Yeol, and Japanese prime minister, Fumio Kishida, both countries are attempting to restore ties and trust with each other. History Between 1961 and 1979, South Korean's head of state was dictator Park Chung-hee, who had served in the Imperial Japanese military during World War II. Park took a strong interest in Japanese modernization since he witnessed development policies in Manchukuo firsthand. After the war, during a private lunch with Prime Minister Nobusuke Kishi, one of the masterminds behind the pre-war Manchukuo economy, Park compared his own South Korean military clique with "the young people who succeeded with Meiji restoration in Japan." He further added that he and his troops "look up to these people, and try to make our country escape from poverty and build a wealthy and powerful nation." Under Park's government, the two countries pursued the 1965 reconciliation treaty, which brought about normalized relations, despite considerable public opposition. Park was able to force the normalization through the National Assembly and shut down demonstrations through martial law. As a result, Tokyo provided $300 million as compensation to comfort women, forced laborers and other victims, and extended an additional $200 million credit to Seoul, and Prime Minister Sato attended official functions in July, the first visit of a
