Japan–Korea relations
Name	Japan–Korea relations

Japan–Korea relations describe the long-standing interactions between Japan and the Korean peninsula polities that evolved into relations between the Empire of Japan, Taisho Democracy, Shōwa period, Occupied Japan, State of Japan institutions and the modern Republic of Korea and Democratic People's Republic of Korea. Relations encompass diplomatic contacts involving the Treaty of Amity and Commerce (Japan–Korea), conflicts such as the Imjin War, and modern engagements through multilateral fora like the United Nations and the Asia-Pacific Economic Cooperation forum.

Historical relations

Early contacts involved envoys from Baekje, Silla, and Gaya confederacy visiting the Asuka period and Nara period courts, exchanging Buddhism and artisans with figures like Prince Shōtoku and transmissions of Seon and Zen practices. The Goryeo dynasty engaged in maritime trade and diplomatic missions with the Kamakura shogunate and later the Ashikaga shogunate, while cultural exchange included texts such as the Jikji and handicrafts influenced by Heian period aesthetics. The late 16th century saw the Imjin War when Toyotomi Hideyoshi launched invasions that involved commanders like Kato Kiyomasa and Yi Sun-sin, culminating in naval engagements including the Battle of Noryang. The 17th century established the Joseon dynasty’s Sakoku-era tributary and trade relations mediated via the Tsushima Domain and the Sō clan’s diplomacy culminating in the Mokpo exchanges and the Joseon missions to Japan.

The 19th century brought unequal diplomacy under treaties such as the Treaty of Ganghwa after Perry Expedition-era pressure by figures tied to Tokugawa shogunate transitions, leading to imperial competition including the First Sino-Japanese War and the Russo-Japanese War, reshaping influence over the peninsula. The Japan–Korea Treaty of 1910 formalized annexation under the Empire of Japan, prompting resistance movements epitomized by the March 1st Movement and exiled leaders like Kim Koo. Post-World War II division after Yalta Conference outcomes led to establishment of the Republic of Korea and the Democratic People's Republic of Korea, while occupation legacies influenced postwar treaties such as the Treaty on Basic Relations between Japan and the Republic of Korea (1965).

Diplomatic and political relations

Diplomatic ties between Tokyo and Seoul have alternated between rapprochement and tensions, mediated by summits between leaders such as Syngman Rhee, Park Chung-hee, Kim Dae-jung, Roh Moo-hyun, Lee Myung-bak, Moon Jae-in, and Japanese prime ministers including Shinzo Abe and Yasuhiro Nakasone. Bilateral normalization in 1965 created frameworks for reparations and cooperation involving the Ministry of Foreign Affairs (Japan) and the Ministry of Foreign Affairs (South Korea), while engagement in multilateral institutions like the Asia-Pacific Economic Cooperation and the ASEAN Regional Forum facilitated trilateral dialogues including United States mediation via summits with presidents such as Dwight D. Eisenhower and later secretariats like the United Nations Security Council often addressing Korean peninsula issues. Relations with the Democratic People's Republic of Korea involve negotiations over abductees such as the Abduction of Japanese citizens by North Korea and six-party talks with participants including China, Russia, and the United States Department of State.

Economic and trade relations

Economic integration includes bilateral commerce in goods and services between Japanese conglomerates such as Mitsubishi and Toyota and South Korean chaebol like Samsung and Hyundai. Trade ties expanded through supply chains linking Keiretsu networks, port hubs such as Busan and Kobe, and agreements influenced by instruments like the World Trade Organization dispute settlement mechanism when firms invoked trade remedies. Investment flows were shaped by post-1965 reparations financing and later by free trade dialogues including negotiations referencing frameworks like the Regional Comprehensive Economic Partnership and Comprehensive and Progressive Agreement for Trans-Pacific Partnership debates. Currency and financial linkages connect central banks, notably the Bank of Japan and the Bank of Korea, while tourism exchanges involve airlines such as Korean Air and Japan Airlines.

Security and military cooperation

Security interactions cover cooperation and friction over missile and nuclear concerns on the peninsula, involving alliances with the United States Armed Forces presence such as United States Forces Korea and the United States Indo-Pacific Command. Joint exercises and information-sharing engage organizations like the Japan Self-Defense Forces and the Republic of Korea Armed Forces alongside trilateral coordination with the U.S. Department of Defense. Historical legacy issues inform defense policy debates in legislatures including the National Diet and the National Assembly (South Korea), while regional security dialogues occur in formats like the Six-Party Talks and forums hosted by NATO observers and ASEAN partners. Incidents at sea involve coast guards such as the Japan Coast Guard and the Korea Coast Guard and have led to legal cases in venues like the International Court of Justice-referenced dispute resolution discourse.

Cultural and social exchanges

Cultural ties encompass the modern Korean Wave and J-pop cross-fandoms, with artists from BTS and AKB48 performing across both markets and festivals hosted in cities like Seoul and Osaka. Academic exchanges link universities such as Seoul National University and University of Tokyo, while museums like the National Museum of Korea and the Tokyo National Museum curate shared artifacts. Migration patterns include Zainichi Koreans with histories tied to Internment during World War II and postwar citizenship debates involving courts like the Supreme Court of Japan. Media and literature flows include translations of works by Haruki Murakami and Kim Young-ha, while culinary exchanges feature dishes such as kimchi and sushi influencing food industries.

Territorial and historical disputes

Territorial disputes focus on islets administered by Japan and South Korea known in Japan as Takeshima and in Korea as Dokdo, and associated administrative claims by provincial governments such as Shimane Prefecture and North Gyeongsang Province. Historical controversies involve wartime labor and comfort women claims litigated in courts like the International Criminal Court-referenced advocacy contexts and addressed in agreements such as the 2015 comfort women accord negotiated between Park Geun-hye and Shinzo Abe. Textbook controversies engage ministries including the Ministry of Education (South Korea) and the Ministry of Education, Culture, Sports, Science and Technology (Japan), while legacy reconciliation efforts cite commissions such as the Japanese Council for the Problem of Japanese Military Sexual Slavery by Korea and civil society groups like The Korean Council for Justice and Remembrance for the Issues of Military Sexual Slavery by Japan.
