Putin's Kuril Islands Visit Ignites Japan-Russia Dispute

Russian President Vladimir Putin's inaugural visit to the South Kuril Islands, a territory Japan claims as its Northern Territories, has escalated the enduring territorial dispute between Moscow and Tokyo. This archipelago, strategically situated between Russia's Kamchatka Peninsula and Japan's Hokkaido, remains the core of a conflict that has prevented the two nations from formally concluding World War II.

The islands, which Japan asserts include Iturup, Kunashir, Shikotan, and Habomai, are the southernmost in a chain of 56 islands stretching from the Kamchatka Peninsula to Hokkaido. Currently administered by Russia's Sakhalin Oblast, Japan denounces their "illegal occupation" and considers these four islands an integral part of its territory. The dispute's roots trace back to the 18th century, with Russia claiming sovereignty based on exploration, and subsequent treaties in the 19th century defining borders and exchanging territories.

Following Japan's defeat in World War II, Soviet forces occupied the islands in the final days of the conflict in August 1945. Russia bases its claim on the Yalta Conference, where it contends U.S. President Franklin Roosevelt agreed to the Soviet Union regaining the Kuril Islands in exchange for entering the war against Japan. Despite numerous attempts over seven decades, the unresolved occupation has blocked a formal peace treaty.

Economically and strategically, the islands hold significant value. The surrounding waters are rich in fishery resources, and the land contains deposits of minerals and rare metals, including rhenium, crucial for supersonic aircraft. Control of the islands grants Russia's Pacific Fleet year-round access to the Pacific Ocean, as the straits between Kunashir and Iturup remain ice-free in winter. Russia maintains military bases and has deployed missile systems on the islands.

The dispute shows no signs of abating. Japan has adopted a firmer stance since Russia's full-scale invasion of Ukraine in 2022. Prime Minister Fumio Kishida stated that Putin's visit "harms the feelings of the Japanese people and is absolutely unacceptable," further complicating any potential for normalized relations. Russia, however, maintains its legal ownership of the islands, asserting there is no room for negotiation.
