Putin's First Visit to the Disputed Kuril Islands Escalates Tensions With Japan
Russian President Vladimir Putin visited the disputed Kuril Islands on Thursday, August 13, 2026, making his first-ever trip to the Russian-administered island chain that Japan also claims as its Northern Territories. The visit drew immediate condemnation from Tokyo, with Prime Minister Sanae Takaichi calling it "absolutely unacceptable" and saying it "offends the sentiments of the Japanese people and goes against Japan's position on the Northern Territories" Al Jazeera.
Putin's itinerary on the southernmost isle of Iturup included meetings with the regional governor and site visits to a fish-processing plant, a hospital, and a school. The islands are home to roughly 20,000 Russian citizens and hold mineral deposits including gold and silver, alongside rich fishing grounds. The Kremlin's presidential website separately reported that between April 24 and August 6, 2026, a total of 1,001 vessels transited the exclusive economic zone of the Russian Federation along the Kuril Islands Kremlin.
Japan's Foreign Minister Toshimitsu Motegi criticized the visit, stating that the disputed islands are "an inherent part of Japan's territory both historically and under international law." Tokyo also lodged two protests with Russia over Moscow's announcement of military exercises around the Kuril Islands France 24.
The territorial dispute dates to the final days of the Second World War. The Soviet Union seized the four southernmost Kuril islands in 1945 and subsequently deported their Japanese population of about 17,000 people. Japan asserts sovereignty over the four islands, known in Russian as Kunashir, Habomai, Shikotan, and Iturup, and in Japanese as Kunashiri, Habomai, Shikotan, and Etorofu. No peace treaty formally concluding hostilities between the two countries has ever been signed.
Putin's visit was preceded by a stop on the nearby island of Sakhalin on Wednesday, August 12, where Russia's navy was conducting drills. On the same day, Putin claimed that international documents confirm Russian sovereignty over the Kuril Islands, including the four islands Japan also claims Nippon.com. He further stated on Wednesday that Japan's sanctions against Russia were "unprovoked," asserting that Russia is not threatening Japan and that it is Japan which holds territorial claims against Russia.
The broader context here is the near-total collapse of Tokyo-Moscow relations since 2022. Japan joined other G7 countries in imposing sanctions — penalties meant to pressure Russia economically — following the full-scale conflict in Ukraine, and also provided financial and non-lethal defense aid to Kyiv. These moves worsened bilateral ties to their lowest point in decades, effectively freezing the tentative engagement that had characterized earlier periods. In 2017, Russia had announced plans to organize a trip by Japanese businesspeople and officials to the South Kuril Islands to study specific cooperation Kremlin. Putin had also previously told the Japanese newspaper Asahi that Japanese citizens and former inhabitants of the Kurils can visit the islands under a simplified procedure and that Japanese fishermen operate in the islands' waters Kremlin. That cooperative framework now appears moribund.
Putin had signaled his intent as early as January 2024, when he said he would "definitely" visit the Southern Kuril Islands one day Reuters. Russia has a history of rejecting Japanese diplomatic protests over official visits to the chain; in July 2021, Moscow dismissed what it called a "hostile" Japanese protest following a visit by the Russian prime minister to the disputed islands Reuters. The difference in 2026 is that the visitor is the head of state, not the head of government.
The Kuril Islands visit also fits into a wider pattern of Russian diplomatic and military activity in the Pacific Far East. Putin's August 2025 talks with U.S. President Donald Trump in Anchorage, Alaska, signaled an effort by Moscow to reposition its diplomatic posture toward the Asia-Pacific Kremlin. The naval drills on Sakhalin and the transit data highlighting over a thousand vessels through the Kuril EEZ in recent months point to a sustained Russian effort to normalize both its civilian and military footprint across the chain.
For Japan, the visit complicates an already constrained strategic position. Tokyo's alignment with G7 sanctions and support for Ukraine has drawn Moscow's ire, and Putin's framing of Japanese sanctions as "unprovoked" signals that Russia intends to use the territorial dispute as leverage rather than as a subject for negotiation. With a peace treaty nowhere in sight and bilateral channels effectively severed, the Northern Territories dispute has shifted from a dormant diplomatic question to an active flashpoint in the broader confrontation between Russia and the U.S.-aligned bloc.
