Russian President Vladimir Putin traveled to the disputed Kuril Islands for the first time, prompting an immediate and strong protest from the Japanese government regarding the sovereignty of the territory known in Japan as the Northern Territories. According to statements published by Japanese Foreign Minister Toshimitsu Motegi on August 13, 2026, Tokyo considers Etorofu Island and the surrounding chain to be its inherent territory.
Japanese Government Response and Diplomatic Protests
Foreign Minister Motegi posted a formal protest on X (formerly Twitter) immediately following the visit, stating that the islands are historically and under international law a part of Japan. According to the Yomiuri Shimbun, government officials in Tokyo are actively evaluating the broader strategic implications of Putin’s unannounced visit to the region.
Itinerary and Military Inspections in the Kuril Islands
During his tour of Siberia and the Russian Far East, Putin arrived directly in the island chain to inspect the flagship of the Russian Pacific Fleet and receive military readiness reports, as reported by Russian state news agency TASS and Agence France-Presse. Following the naval inspection, Putin met with Sakhalin Region Governor Valery Limarenko and visited civilian infrastructure on Etorofu Island, including a seafood processing plant, a local school, and a medical facility. Dmitry Medvedev, Russia’s Security Council Deputy Chairman and former President, visited the islands in 2010, marking the first visit by a Russian leader; this journey marked Putin’s first personal trip to the territory.
Geopolitical Context and Bilateral Friction
The visit underscores hardening positions amid the nearly four and a half years of conflict in Ukraine. Speaking in Yuzhno-Sakhalinsk prior to his island tour, Putin criticized Tokyo for enacting unilateral sanctions against Moscow without accounting for the underlying causes of the Ukraine crisis. At the same time, Putin asserted that Russia poses no military threat to Japan and harbors no territorial claims against it, responding to Tokyo’s defense white paper released earlier in the month which expressed deep concern over expanding military cooperation between Russia, China, and North Korea.
Resource Significance and Historical Background
The Kuril Islands comprise four southern islands—Kunashir, Etorofu, Shikotan, and Habomai—administered by Moscow since Soviet forces seized them in the final days of World War II in 1945. Though the current population stands at approximately 20,000 residents, the surrounding waters and landmasses hold immense strategic value, featuring rich fisheries and substantial deposits of gold and silver. Despite decades of intermittent diplomatic talks aimed at signing a formal post-WWII peace treaty, the sovereignty dispute over the islands remains a central obstacle in Russo-Japanese relations.
