Russian President Vladimir Putin visited Itouroup, one of the four islands in the southern Kuril chain, on August 13, 2026, marking a rare and contentious presidential trip to the territory. The visit, which included stops at a fish processing plant, a hospital, and a school, has triggered a sharp diplomatic rebuke from Japan, which claims the islands as its own "Northern Territories."
Diplomatic Fallout Between Tokyo and Moscow
The Japanese government reacted swiftly to the visit, with Prime Minister Sanae Takaichi describing the trip as "absolutely, unacceptable" and stating it "hurts the feelings of the Japanese people," according to reporting by TV5Monde. Foreign Minister Toshimitsu Motegi summoned the Russian ambassador to Japan, Nikolaï Nozdrev, to issue a formal protest.
Japan maintains that the four islands are integral parts of its territory, both historically and legally. This position has been reinforced since the start of the conflict in Ukraine in February 2022, when Japan officially labeled the southern Kurils as being "illegally occupied."
The Russian Position on Sovereignty
Russian officials have dismissed the Japanese protests as groundless. Maria Zakharova, a spokesperson for the Russian Foreign Ministry, rejected the criticism in a formal statement, characterizing Japan’s reaction as a "policy of anti-Russian sentiment bordering on hostility."
According to Zakharova, Russia’s jurisdiction over the islands is not in doubt, and she criticized the Japanese leadership for attempting to dictate which regions of Russia its head of state may visit. President Putin himself addressed the tension during his time in the region, stating that Russia does not view Japan as a threat. Instead, he argued that it is Tokyo that continues to pursue territorial claims against Russia.
Historical Context of the Kuril Dispute
The territorial disagreement stems from the final days of World War II, when Soviet forces seized the four islands in 1945. The two nations rely on different historical frameworks to justify their claims:
- Japan’s Stance: Tokyo points to the Treaty of 1855, which established the border between the two nations just north of the four islands.
- Russia’s Stance: Moscow relies on the 1945 Yalta Conference, where Allied powers agreed that the Kuril Islands would be ceded to the Soviet Union in exchange for its entry into the war against Japan.
This ongoing dispute has prevented Russia and Japan from signing an official peace treaty to formally conclude their World War II hostilities.
Did you know? Approximately 20,000 Russian citizens live in the Kuril Islands, according to TV5Monde.
Military Tensions and Regional Security
The presidential visit occurred shortly after significant Russian naval exercises in the Far East, which involved 60 vessels and 30 aircraft. While the Russian government maintains these are internal security measures, the proximity of such exercises to Japanese territory remains a point of friction.
Japan’s defense posture has evolved as it monitors increased cooperation between Russia and China in the region. The two nations have conducted joint naval and air patrols, forcing Japanese aircraft to scramble in response hundreds of times annually. Meanwhile, the United Nations has called for restraint from all parties involved, with spokesperson Shirin Yassen noting that the situation is a bilateral matter between two member states that requires responsible action to avoid escalating tensions.
