Context
Russian President Vladimir Putin visited the disputed Kuril Islands (specifically Iturup Island) for the first time, triggering strong protests from Japan. The dispute centres around four islands—Iturup, Kunashir, Shikotan, and Habomai—which have been under Russian control since World War II but are claimed by Japan as its 'Northern Territories.' This long-standing territorial dispute has prevented the two nations from signing a formal peace treaty to officially end World War II hostilities.
UPSC Perspectives
Geographical
For UPSC Prelims, mapping questions frequently test knowledge of disputed territories and maritime boundaries. The Kuril Islands are a volcanic archipelago stretching approximately 1,200 km across the North Pacific Ocean, separating the Sea of Okhotsk from the main Pacific Ocean. They lie just north of Japan's northernmost prefecture, Hokkaido. The specific dispute focuses on the four southernmost islands: Iturup, Kunashir, Shikotan, and the Habomai islets. Russia administers these as part of its Sakhalin region, while Japan claims them as part of Hokkaido, referring to them as the Northern Territories. Aspirants should locate these islands on a map relative to the Kamchatka Peninsula (Russia) and Hokkaido (Japan), and understand their strategic location controlling access between the Sea of Okhotsk and the Pacific.
Polity
The dispute highlights the complexities of international law and the interpretation of historical treaties in resolving territorial conflicts. Japan's claim is rooted in 19th-century agreements, notably the [Treaty of Shimoda] (1855), which first established the boundary between the two nations, and the [Treaty of St. Petersburg] (1875). Conversely, Russia's claim rests on post-World War II agreements. Moscow points to the [Yalta Agreement] (1945), where the Allied powers promised the Kurils to the Soviet Union in exchange for entering the war against Japan. Russia also cites the [San Francisco Peace Treaty] (1951), where Japan renounced claims to the Kuril Islands. However, Tokyo argues that the is invalid regarding this dispute because the Soviet Union refused to sign it, and further contends that the four specific islands in question are not geographically part of the 'Kuril chain' that was renounced. This differing interpretation of treaty law is a classic example of how historical ambiguities perpetuate modern geopolitical standoffs.
International Relations
From a strategic perspective, the Kuril Islands dispute is a major impediment to bilateral relations between Russia and Japan. The lack of a formal peace treaty means the two nations remain technically at war since 1945. The islands hold significant geostrategic value. For Russia, they secure naval access for its Pacific Fleet (based in Vladivostok) out to the open ocean and provide a buffer zone. For Japan, resolving the issue is a matter of national pride and sovereignty. The timing of Putin's visit is also critical; occurring shortly before Japan's commemoration of its WWII surrender and amid rising regional tensions involving North Korea, South Korea, and the US. This move signals Russia's intent to assert its sovereignty unequivocally, complicating any future diplomatic negotiations and potentially driving Japan closer to its Western allies in the broader Indo-Pacific security architecture.
