A Complex Legacy: The 2,000-Year History of Japan-Korea Relations

Spanning over two millennia, these interactions have shaped the geopolitical landscape of East Asia. While Korea has historically served as a vital conduit for transmitting continental Asian culture, technology, religion, and political ideas to Japan, the shared history is also marked by deep-seated tensions and scars from periods of colonial rule.

Pre-Modern and Early Modern Eras
In the early centuries, the two regions engaged in various forms of contact. By the 16th century, relations were often defined by conflict, most notably during the Imjin War (1592–1598). This period of Japanese invasions remains a critical element in the historical consciousness of both nations.
The Tokugawa Era and Diplomatic Missions
Following the wars, a period of stabilized relations emerged under the Tokugawa shogunate. In 1609, the Treaty of Giyu was concluded with the Sō clan of Tsushima Island, establishing a relationship of near equality. This era was characterized by Tsushinshi—official Korean diplomatic missions sent to Japan to pay homage to the shogun or celebrate significant events. Between 1607 and 1811, Korean missions were dispatched to the Tokugawa shogunate 11 times, serving as a means of mutual prestige.
The 19th Century: Modernization and Encroachment
The 19th century brought rapid shifts in power. As the authority of the Qing dynasty in China weakened, Korea sought to resist traditional subservience to China. Simultaneously, Japan was undergoing rapid modernization and feared that China or Russia might use the Korean peninsula to threaten Japanese interests.
The Japan–Korea Treaty of 1876 marked a turning point, allowing Japan to expand its settlements and acquire an enclave in Busan. Internal Korean politics were also volatile, characterized by power struggles between Heungseon Daewongun and Empress Myeongseong. Following Japan's victory in the First Sino-Japanese War (1895), the Treaty of Shimonoseki removed China's suzerainty over Korea, effectively recognizing it as an "independent" nation while Japan began increasing its influence.
In an attempt to assert sovereignty, Joseon was renamed the Korean Empire in 1897. However, the empire gravitated closer to Russia, with the King often ruling from the Russian legation to protect against rising Japanese power.
The 20th Century: Annexation and Colonial Rule
The transition from a protectorate to full annexation was marked by intense resistance. In 1907, Japan imposed a treaty that gave it full control over Korea's domestic affairs and disbanded the Korean army. Despite efforts by Emperor Gojong to denounce these terms at the Hague Peace Conference, Japan moved toward outright annexation.
On August 22, 1910, the Japan-Korea Annexation Treaty was imposed, officially bringing Korea under Japanese rule. This period saw significant Korean resistance, including the independence movements led by figures like Kim Il Sung in the border regions of China and Russia, and the Provisional Government of the Republic of Korea, which coordinated armed resistance from locations such as Shanghai and Chongqing.
Wartime Service and Hardship
During the colonial period, more than 100,000 Koreans served in the Imperial Japanese Army through both voluntary and forced enlistment. This era was also marked by the profound suffering of "comfort women"—women sent to the war frontlines to serve the Imperial Japanese Army. The legacy of this period continues to influence modern diplomacy and historical interpretations.
Post-War Realities and Modern Diplomacy
Following Japan's defeat in World War II, Korea was divided into Soviet and American occupation zones, leading to the creation of North and South Korea in 1945. The subsequent Korean War (1950–1953) further complicated the regional landscape.
Diplomatic relations between Japan and South Korea were formally established in 1965 via the Treaty on Basic Relations. However, several issues remain unresolved, including territorial disputes over the Liancourt Rocks and disagreements over wartime memory and history textbooks. In 2015, a significant attempt was made to address the "comfort women" issue through a 1 billion yen donation and apologies from Prime Minister Shinzō Abe, though the agreement faced domestic criticism in South Korea.
Today, relations continue to evolve. While Japan and South Korea work through complex historical grievances, Japan and North Korea remain without formal diplomatic relations, with tensions persisting over the abduction of Japanese citizens in the 1970s and 1980s.
