Anti-Japanese sentiment Due to collective memory of the Korean society of cruelty brought upon them in the era of
Imperial Japanese rule, anti-Japanese sentiments have resided and still persists in Koreans through public education, although personal level interactions have proven to improve perceptions towards Japanese people. Contemporary Korean nationalism, at least in South Korea, often incorporates
anti-Japanese sentiment as a core component of its ideology. The legacy of the colonial period of Korean history continues to fuel recriminations and demands for restitution in both Koreas. North and South Korea have both lodged severe protests against visits by Japanese officials to the
Yasukuni Shrine, which is seen as glorifying the Class A
war criminals whose remains are held there. South Koreans claim that a number of Korean women who worked near Japanese military bases as
comfort women were forced to serve as sex slaves against their will for Japanese soldiers during
World War II which had been a persistent thorn in the side of Japan-South Korea relations from the 1990s to the 2010s. Disagreements over demands for reparations and a formal apology still remain unresolved despite the previous agreement and compensation in 1965, South Koreans started peaceful vigils in 1992 held by survivors on a weekly basis. Recent
Japanese history textbook controversies have emerged as a result of what some see as an attempt at historical negationism with the aim of whitewashing or ignoring Japan's war crimes during
World War II. These issues continue to separate the two countries diplomatically, and provide fuel for nationalism in both Koreas as well as anti-Japanese sentiment. According to
Robert E. Kelly, a professor at
Pusan National University, anti-Japanese sentiment in South Korea stems not just from Japanese atrocities during the occupation period, but also from the Korean Peninsula's division. Anti-Japanese sentiment in Korea has decreased in the 2020s; according to a poll in conducted in late 2025 by the Japanese Public Interest Incorporated Newspaper and the Communications Research Association, 56.4% of South Koreans had a favorable view of Japan, with favorability especially high in those in their 20s and 30s.
Liancourt Rocks dispute The
Liancourt Rocks dispute—concerning the islands known as Dokdo or Tokto (독도/獨島, literally "solitary island") in Korean and Takeshima in Japanese—has remained unresolved since the early post-World War II period. In the 1951
Treaty of San Francisco, the United States did not include the islands in the territories relinquished by Japan to South Korea, a decision South Korea contested, particularly in light of a U.S. diplomatic note (the
Rusk documents) favoring Japanese sovereignty. South Korea has exercised effective control over the islands since the mid-1950s, establishing a permanent coast guard presence in 1954, while Japan has maintained its claim through administrative measures, such as incorporating the islands into
Shimane Prefecture in 1905 and periodic diplomatic protests against what it views as an unlawful occupation. Both sides base their claims on historical records stretching back centuries, with interpretations often diverging due to ambiguities in ancient texts and maps. South Korea asserts ancient sovereignty, citing records from the
Three Kingdoms of Korea period, such as the
Samguk Sagi (1145, recording events from 512 CE), which describes the conquest of Usan-guk—an entity including Ulleungdo and what Koreans identify as Dokdo—by the
Silla kingdom. Medieval sources, including the geography section of the
Sejong sillok (part of the
Veritable Records of the Joseon Dynasty), note that Usando (Dokdo) and Mureungdo (Ulleungdo) are visible from each other on clear days, affirming their proximity and Korean administration under
Gangwon-do. In the 17th century, Korean official
An Yong-bok's voyages (1693–1696) reportedly secured acknowledgments from Japanese authorities that both Ulleungdo (Takeshima) and Dokdo (Matsushima) belonged to Korea, as documented in the
Sukjong sillok (Annals of King Sukjong). 16th-century geographies, such as the
Sinjŭng Tongguk yŏji sŭngnam (1530, revised 1531), depict Usando as part of Korean territory. Later maps like the
Haejwa Jeondo (c. 1822) also include depictions interpreted by Korea as showing the rocks. In 1900, Imperial Ordinance No. 41 of the
Korean Empire explicitly included Seokdo (a phonetic rendering of Dokdo) under the administration of Uldo County (Ulleungdo). Japan, conversely, argues that the rocks were historically terra nullius (unclaimed land) until their formal incorporation in 1905. Japanese interpretations suggest that early Korean references to Usan-do likely refer to Jukdo (a small islet near Ulleungdo) or a non-existent island, rather than the Liancourt Rocks, due to inconsistencies in described visibility and location. In the Edo period, documents like the 1667 *Inshu Shicho Goki* mention Matsushima but do not assert sovereignty. Japan points to the 1695 inquiry by the Tokugawa shogunate to the Tottori clan, which confirmed that neither Takeshima (Ulleungdo) nor Matsushima (Liancourt Rocks) belonged to Japanese provinces, leading to the revocation of fishing licenses in 1696 as they were foreign territory. An 1877 directive from the
Daijō-kan (Japan's early Meiji government) excluded Takeshima and "another island" (interpreted by Japan as not referring to Liancourt) from Japanese land registries. Japan emphasizes its 1905 Cabinet decision to annex the uninhabited rocks amid fishing interests and the
Russo-Japanese War, following a petition by fisherman Nakai Yozaburo, with no prior effective Korean occupation documented. The dispute is intertwined with nationalist sentiments in both countries, though the expressions and underlying motivations differ due to historical asymmetries. In South Korea, the islands hold profound symbolic significance as a representation of reclaimed sovereignty after Japan's colonial rule over Korea from 1910 to 1945. Many Koreans perceive Dokdo as the initial territory seized during Japan's imperial expansion—incorporated amid fishing interests and the
Russo-Japanese War—and thus emblematic of overcoming historical humiliation and affirming post-colonial independence. This emotional attachment elevates the issue beyond material value, linking it to broader grievances like forced labor, comfort women, and history textbook disputes, and making concessions politically sensitive as they could be seen as undermining national dignity. South Korean governments have at times leveraged this symbolism in response to diplomatic tensions or for domestic political purposes. For instance, during a 2006 flare-up involving Japanese maritime surveys and exclusive economic zone (EEZ) claims, President
Roh Moo-hyun framed the issue in a speech as tied to historical rectification, stating: Roh connected it to other controversies, such as
Yasukuni Shrine visits and textbook distortions, emphasizing that it would be addressed in the context of safeguarding Korea's sovereignty and independence, with no room for compromise under those circumstances. Such rhetoric has contributed to public mobilization, where the islands serve as a rallying point for national pride and resistance to perceived Japanese revisionism. Nationalist mobilization, however, is mutual. In Japan, conservative politicians, Shimane Prefecture officials—who have observed "Takeshima Day" annually since 2005—and civic groups portray the islands as inherent territory from historical times, unlawfully occupied by South Korea post-war. This framing often ties into narratives of defending Japan's territorial integrity against what is seen as Korean overreach or politicization of history. Public opinion in both nations reflects strong majorities supporting their respective claims, with protests and media attention more pronounced in South Korea, but Japanese educational materials and diplomatic statements reinforcing the claim. Scholars highlight that while identity-based and emotional factors complicate resolution, the impasse is also driven by diverging historical interpretations, legal ambiguities in post-war treaties, strategic interests in fishing rights and EEZs, and domestic political incentives to avoid appearing conciliatory. As French theorist
Ernest Renan noted, "Where national memories are concerned, griefs are of more value than triumphs, for they impose duties, and require a common effort," a dynamic evident in territorial narratives on both sides. Despite these challenges, periods of improved bilateral relations—such as through economic partnerships or summits—have seen de-escalation in rhetoric, indicating that nationalism, while influential, is modulated by broader political contexts rather than an insurmountable barrier.
Manchuria and Gando disputes Expressions of Korean interest in Manchuria (now
Northeast China) can be traced to the late
Joseon dynasty, when writings frequently evoked nostalgia for the "old lands of Goguryeo" as part of a broader cultural and historical memory of northern territories once associated with ancient kingdoms. In the early 20th century, nationalist historians such as
Shin Chaeho advocated for the unification of the Korean Peninsula with Manchuria, framing it as the restoration of the "ancient lands of
Dangun" and emphasizing shared ethnic and historical heritage. In modern times, some nationalist Korean historians and fringe groups have put forward irredentistF claims asserting that parts of Manchuria—particularly the
Gando region (known in China as Jiandao and encompassing the
Yanbian Korean Autonomous Prefecture bordering China, North Korea, and Russia)—should belong to Korea. These arguments are based on the historical control or influence of ancient entities such as
Gojoseon,
Goguryeo (37 BCE–668 CE), and
Balhae (698–926 CE) over much of what is now Northeast China, which Korean historiography regards as foundational proto-Korean states. The term "Greater Korea" occasionally appears in such nationalist literature to describe an expanded historical territory that includes these regions. Claims to Gando tend to be more focused than broader Manchurian irredentism. Supporters point to Balhae's continued presence in the area after Goguryeo's fall, the significant ethnic Korean population in Yanbian (approximately one-third of residents), and the 1909
Gando Convention, which many Koreans view as having illegitimately ceded the region to Chinese control under Japanese colonial coercion. From the Chinese perspective, Goguryeo and Balhae are framed as integral components of China's multi-ethnic historical narrative. Chinese historiography typically describes them as "local regimes" or "minority states" founded by ethnic groups (such as the Yemaek or Mohe) that operated on the northeastern frontier, interacted with and often paid tribute to successive Chinese dynasties (Han, Sui, Tang, etc.), and were eventually absorbed into Chinese imperial territory. This framing presents the kingdoms as part of the continuous, multi-ethnic evolution of what became modern China, rather than as exclusively Korean polities. The differing framings of Goguryeo and Balhae reflect nationalist sensitivities on both sides. Korean interpretations often emphasize the kingdoms as core elements of Korean ethnic identity and lost northern homelands, while Chinese interpretations stress historical unity, frontier interactions, and multi-ethnicity to reinforce territorial integrity and national cohesion in border regions. These issues came to the forefront in South Korea during the 2004
Goguryeo controversies, sparked by China's
Northeast Project (2002–2007), a state-sponsored research effort that reclassified Goguryeo and Balhae as part of Chinese history. Many Koreans perceived this as an attempt to appropriate shared heritage and preempt potential irredentist claims. In response, 59 South Korean lawmakers introduced a bill declaring the 1909 Gando Convention "null and void" and asserting Korean territorial rights over Gando. The proposal did not become law and remained a fringe position without official government endorsement. Later in 2004, the governments of South Korea and China reached a verbal understanding to refrain from official involvement in historical controversies, agreeing to leave such debates to academic historians. Scholars from various backgrounds note that these disputes largely stem from the anachronistic application of modern national identities to ancient, multi-ethnic polities that did not correspond neatly to contemporary borders or ethnic categories. While irredentist claims concerning Manchuria or Gando have remained marginal and unofficial in South Korea, and China continues to administer the region while maintaining its historical framing of the kingdoms, the episode illustrates how competing interpretations of ancient history can intersect with modern national identity and bilateral relations. Since the 2004 agreement, both countries have generally managed the issue through dialogue rather than politicization, allowing economic and diplomatic cooperation to take precedence. ==See also== •
