South Korea’s sharp criticism of Japan over the commemoration of “Takeshima Day” has once again brought the long-running territorial dispute over a small cluster of islets in the Sea of Japan (East Sea) into focus. While the territory is geographically tiny, its historical symbolism, strategic location, and potential economic value make it a sensitive diplomatic flashpoint in Northeast Asia.
What Triggered the Latest Diplomatic Protest?
The controversy followed the annual observance of “Takeshima Day” by Shimane Prefecture, a Japanese administrative region that claims jurisdiction over the disputed islets. The event, established in 2005, commemorates Japan’s assertion of sovereignty over the territory.
South Korea reacted strongly, objecting to the participation of a senior Japanese government official in the ceremony. Seoul summoned a senior diplomat from the Japanese Foreign Ministry to lodge a formal protest, calling the event an unjustified claim over what it considers its sovereign territory.
Dokdo or Takeshima: A Legacy of Colonial History
The islets are known as “Dokdo” in South Korea and “Takeshima” in Japan. The dispute dates back to Japan’s colonial rule over the Korean Peninsula (1910–1945). After World War II and Korea’s liberation, the question of sovereignty over several territories, including these islets, became contentious.
In 1954, South Korea stationed a coastguard detachment on the islands and has since exercised effective administrative control. Japan, however, continues to assert its claim, arguing that the territory historically belongs to it and was incorporated into Japan prior to the colonial annexation of Korea.
Geographical and Strategic Significance of the Islets

The disputed territory comprises two main islets and around 30 smaller rocks, located roughly midway between the Korean Peninsula and Japan’s Honshu island. Internationally, they are sometimes referred to as the Liancourt Rocks.
Their significance stems from multiple factors:
- Strategic Location: The islets sit in important maritime routes in the Sea of Japan (East Sea).
- Fishing Grounds: The surrounding waters are rich in marine resources, making them economically valuable.
- Energy Potential: South Korea argues that the seabed may contain natural gas hydrate deposits, sometimes called “combustible ice,” which could have substantial economic worth.
- Maritime Jurisdiction: Control over the islets affects the delimitation of Exclusive Economic Zones (EEZs) under international law.
Legal and Diplomatic Dimensions of the Dispute
South Korea maintains that Dokdo is its sovereign territory “historically, geographically and under international law.” It argues that effective control since 1954 strengthens its legal position. Japan, on the other hand, has proposed referring the dispute to the International Court of Justice (ICJ), a move Seoul has consistently rejected, stating that there is no dispute to adjudicate.
The issue regularly resurfaces in diplomatic exchanges, parliamentary speeches, and school textbook revisions in Japan, which South Korea views as reinforcing territorial claims.
Why the Issue Matters Beyond Symbolism?
Although the islands themselves are small and sparsely habitable, the dispute carries wider geopolitical implications:
- Historical Memory: The dispute is deeply linked to unresolved grievances from Japan’s colonial rule.
- National Identity: Both countries frame the issue as a matter of sovereignty and national pride.
- Regional Security: Tensions complicate trilateral cooperation among South Korea, Japan, and the United States in dealing with North Korea and broader Indo-Pacific challenges.
- Resource Competition: Maritime resources and potential energy deposits heighten the stakes.
What to Note for Prelims?
- Location of Dokdo/Takeshima (Sea of Japan/East Sea).
- Alternate international name: Liancourt Rocks.
- South Korea exercises effective control since 1954.
- Dispute linked to Japan’s colonial rule (1910–1945).
- Relevance to EEZ and maritime boundary issues under UNCLOS.
What to Note for Mains?
- Role of historical memory in shaping contemporary foreign policy.
- Territorial disputes and their impact on regional cooperation in East Asia.
- Strategic importance of small islands in maritime geopolitics.
- Limits of international adjudication when one party rejects third-party arbitration.
