On Thursday, August 13, 2026, Russian President Vladimir Putin made his first-ever personal visit to the Kuril Islands, stepping onto the volcanic soil of Iturup—one of the four southernmost islands in the chain that Russia administers but Japan also claims. The trip, which came after Putin oversaw Russian Pacific Fleet military exercises in the Far East, included tours of local infrastructure and brief interactions with residents, drawing an immediate and strong diplomatic protest from Tokyo. In a move laden with symbolism, Putin’s presence on Iturup underscored Moscow’s resolve to maintain control over the disputed archipelago while relations with Japan remain at a post–Cold War low.
The Visit Unfolds: From Military Drills to Fish Roe
The schedule of Putin in Iturup involved a mixture of security and domestic development-related elements. At least according to the reports of the Russian state media, the president flew to the island after having attended the last part of Pacific Fleet exercises in Yuzhno-Sakhalinsk, where he inspected several important facilities. First of all, he saw a local fish-processing plant named Yasny, from which he was shown how the local fishing industry operates and tasted some caviar and fish roe—an acknowledgment of the economic opportunities of the area.
Moreover, Putin visited the Kuril Central District Hospital and a school with the name of a Hero of Russia, where he met with the locals and discussed issues with the governor of Russia’s Sakhalin Region Valery Limarenko, who governs the islands. Thus, in the Russian media, the trip of Putin was associated with reviewing eastern border security and development of the Far East; according to TASS, “these islands are an important region of our country.”
Tokyo’s Immediate Rebuke: “Strongly Protests This Visit”
Japan’s reaction was swift and unequivocal. Within hours of the visit, Tokyo lodged a formal, strong protest, reiterating its claim that the islands are Japanese territory. Foreign Minister Toshimitsu Motegi issued a statement that captured the government’s position in stark terms:
“The Northern Territories are an inherent part of Japan’s territory both historically and under international law, and the government of Japan strongly protests this visit.”
The phrase “Northern Territories” is Japan’s preferred name for the four southernmost Kuril Islands—Iturup (Etorofu), Kunashir (Kunashiri), Shikotan, and the Habomai islets—which Tokyo considers illegally occupied by Russia.
Prime Minister Sanae Takaichi echoed the sentiment, calling Putin’s trip “absolutely unacceptable” and emphasizing that Japan would continue to press its claim through diplomatic channels. The Japanese government’s stance has long tied resolution of the islands dispute to signing a formal peace treaty ending World War II hostilities with Russia, a treaty that remains elusive eight decades after the war’s end.
The Kuril Islands Dispute: Eight Decades of Stalemate
The origin of the conflict regarding the Kuril Islands goes back to the last months of World War II and the occupation of the southern Kuril Islands by Soviet troops in August 1945. With the signing of the San Francisco Peace Treaty in 1951, Japan formally renounced its claims on the Kuril Islands; however, without recognition of Russian or Soviet sovereignty of the southern four islands, giving Japan an opportunity for legal claim for their return. In contrast to Japan, Russia bases its claim on wartime agreements like the Yalta Conference in 1945 and the outcome of World War II as the justification of its sovereign claim.
At the moment, the disputed four islands of Iturup, Kunashir, Shikotan, and Habomai are under Russian administration as a part of Sakhalin region of the Russian Far East. Geographically, the disputed islands are part of the volcanic islands forming the boundary between Japan and Russia from the Hokkaido area of Japan to the Kamchatka Peninsula of Russia and providing access to the Sea of Okhotsk. Despite previous visits by Russian officials, including Dmitry Medvedev in 2010, Putin’s visit was the first for him personally in 2026.
Strategic Context: Why Now, and What It Signals
The fact that Putin made his visit at this particular time was not coincidental at all. This came in light of the deteriorating relations between Russia and Japan following the war in Ukraine, with the latter adopting an approach that was aligned with the sanctions imposed by the West on Moscow. Indeed, in February 2026, the Kremlin stated that relations with Japan had “become zero,” with no talks ongoing toward signing a peace treaty because of the latter’s “unfriendly” attitude. Given this context, there were several objectives in Putin’s visit to Iturup.
Analysts view the visit as a calculated move to cement Russia’s position ahead of any future negotiations, while also reminding Japan and its allies that the islands are integrated into Russia’s security architecture. Iturup, in particular, hosts Russia’s primary military air base in the region, underscoring the archipelago’s role in Pacific defense planning. By walking the ground and engaging with locals, Putin personalized Moscow’s claim, making it harder for future leaders to backtrack without appearing weak.
Diplomatic Fallout and the Path Ahead
The Japanese objection was more than just words; it was a formal diplomatic note sent in the official channel and strengthening the legal and historical claims made by Japan. But since Moscow rejects the interpretation by Japan and insists on the sovereignty over the disputed territories not being negotiable, the path to a solution remains closed for now. The actions by the Russians, such as renaming one of the disputed islands after a spy of the Soviet Union working in Imperial Japan, make the situation even more heated, demonstrating that the official position of Russia is still hardening.
It seems like for Japan, it is quite difficult to find a balance between standing on principle and negotiating with the enemy. On the one hand, the dispute must be solved in favor of Japan, but the truth is that the control over the disputed territory is firmly established by Russia, and it does not give any incentives to the Russians to come up with a solution.
Voices from the Ground: What Residents and Officials Said
On Iturup, residents greeted Putin with a mix of curiosity and pride, with some expressing appreciation for the attention to local infrastructure. Russian officials framed the visit as a boost for the region’s development, with Governor Limarenko highlighting ongoing projects in healthcare, education, and fisheries. Meanwhile, Japanese officials emphasized the human cost of the dispute, pointing to elderly former residents who still dream of returning to their ancestral homes.
The contrast in narratives is stark: Moscow sees the islands as an integral part of Russia’s Far East, while Tokyo views them as stolen territory that must be returned. As Motegi put it,
“The Northern Territories are an inherent part of Japan’s territory both historically and under international law,”
a line that encapsulates Japan’s legalistic approach. For Russia, the message is equally clear: the islands are Russian, and Putin’s footsteps on Iturup are proof.
The Bigger Picture: A Dispute That Defines a Relationship
The problem of the Kuril Islands is much more than just a territorial conflict – it defines Russian-Japanese relations, influences diplomatic and security policies and even cultural memories. For almost eight decades, the problem has blocked any progress toward a formal peace agreement, raised nationalist feelings in both nations and hindered their regional cooperation efforts. The visit of Putin has been symbolic, but it has only deepened the conflict, making it difficult to envision a compromise acceptable to both parties. Still, this issue shows how ineffective diplomacy can be when facing deeply established positions and national strategies. Until Russia sees the islands as a crucial part of its Pacific defense and Japan treats the problem as an issue of honor, the situation will stay the same. For the time being, Putin’s first visit to the Kuril Islands is only a confirmation that some problems are difficult to solve and symbolism can be just as important as strategy.
