Putin Visits Disputed Kuril Island, Drawing Strong Protest From Japan

Russian President Vladimir Putin has visited the Kuril Islands, according to Russian state media reporting on a Thursday, drawing an immediate and forceful protest from Tokyo. Japan's foreign minister, Toshimitsu Motegi, said in a statement on X that the Kuril islands are "inherently Japanese territory both historically and under international law" and that the Government of Japan strongly protests Putin's visit BBC.

The island Putin visited is known in Russia as Iturup and in Japan as Etorofu. It sits at the centre of a territorial dispute between Moscow and Tokyo that has persisted for decades and prevented the two countries from signing a peace treaty after World War Two BBC.

The dispute traces back to the closing days of the Second World War, when Soviet forces seized the southernmost Kuril islands, which Japan calls the Northern Territories. The 1855 Treaty of Shimoda, Commerce and Navigation had established Japan's possession of what Putin himself later acknowledged as the South Kuril ridge, though Moscow has never accepted any obligation to return all four disputed islands. In a past interview with journalists, Putin said that "no one has stated the Russian government plans to return the South Kuril Islands" and that Russia is negotiating "while recognising the problem" Kremlin. Putin also discussed visa-free travel by Japanese citizens to the South Kuril Islands in a 2016 interview with Nippon TV and Yomiuri Kremlin.

Putin's visit fulfils a pledge he made in January 2024, when he said he would definitely one day visit the Southern Kuril Islands, which are at the centre of the dispute with Japan Reuters. The visit is the latest in a pattern of high-profile Russian official trips to the island chain, each of which has provoked diplomatic friction.

In 2019, Japan called Russian Prime Minister Dmitry Medvedev's visit to an island claimed by both countries "extremely regrettable" Reuters. Two years later, in July 2021, Russia rejected what it called a hostile Japanese diplomatic protest following a visit by the Russian prime minister to the disputed island chain Reuters. In 2017, Japan lodged a formal protest against Russia's naming of five uninhabited islands in the Kuril chain CNN.

The current visit comes amid heightened tension. On August 5, 2026, Japan issued a protest over Russian military drills conducted near the disputed Kuril Islands The Moscow Times. That protest and Putin's trip, occurring within the same month, place the territorial question at the forefront of the bilateral relationship at a moment when diplomatic channels between Moscow and Tokyo are already strained by broader geopolitical alignments.

Putin had previously been scheduled to visit Japan for the 150th anniversary of the Treaty of Shimoda, a diplomatic event tied directly to the origins of the Kuril dispute Georgetown University. The treaty, signed in 1855, established the border between Russia and Japan between the islands of Etorofu and Uruppu, placing the southern Kurils under Japanese sovereignty. That arrangement held until the Soviet occupation at the end of the Second World War.

Russian engagement with the islands has extended beyond political visits to infrastructure and economic development. A Kremlin-published report documents a presidential trip to the Kuril Islands that included visits to a geothermal station, a church on Kunashir Island, a food shop, and the Yuzhno-Kurilsk fish plant Kremlin. In 2014, senior Russian official Sergei Ivanov visited the town of Kurilsk on Iturup, where he toured a local school and its sports field and spoke with students Kremlin.

The broader context here is that Putin's visit consolidates Russia's de facto administrative control over the disputed islands in the most visible way available to a head of state. Each such visit serves multiple functions: it signals domestic audiences that the territory is non-negotiable, it tests the temperature of Tokyo's response, and it complicates any future diplomatic framework that might contemplate even partial territorial concessions. Japan's reaction, while consistent with decades of policy, faces limits. Tokyo can issue protests and suspend diplomatic engagement, but it lacks leverage to alter the facts on the ground. With Russia increasingly oriented away from Western-aligned partners and toward partnerships that do not condition engagement on the Kurils question, the cost to Moscow of Japan's displeasure has arguably diminished.

For Japan, the dispute carries weight beyond the four islands themselves. Tokyo's inability to reclaim the Northern Territories complicates its post-war reconciliation narrative and constrains the strategic calculus in the northwestern Pacific. The absence of a formal peace treaty between Japan and Russia, now over eight decades in the making, is not merely symbolic: it limits the scope of bilateral cooperation on energy, maritime security, and regional defence architecture at a time when the Indo-Pacific balance is in flux.
