Japan Condemns Putin’s First Visit to Disputed Kuril Islands as Russia-Tokyo Tensions Intensify!
Japan has strongly protested Russian President Vladimir Putin’s first visit to the disputed Kuril Islands, describing the move as unacceptable and warning that it further complicates already strained relations between Tokyo and Moscow.
Putin visited Iturup, known as Etorofu in Japan, on Thursday, August 13, 2026, marking the first time the Russian president has travelled to the disputed island chain since taking office. The visit immediately triggered a diplomatic response from Tokyo and revived attention on one of East Asia’s longest-running territorial disputes. (Reuters)
The islands, controlled by Russia but claimed by Japan, have remained at the centre of a territorial disagreement dating back to the final days of the Second World War. Japan refers to the four southernmost disputed islands as the “Northern Territories”, while Russia incorporates them into the southern Kuril chain.
The dispute has prevented Russia and Japan from concluding a formal post-World War II peace treaty, despite decades of intermittent negotiations and attempts at diplomatic rapprochement.
Putin’s decision to visit Iturup therefore carries significance beyond the itinerary of a Russian head of state. For Tokyo, the presence of the Russian president on territory Japan considers its own represents a direct challenge to its longstanding sovereignty position.
Putin tours Iturup during first presidential visit
During his visit, Putin toured local facilities on Iturup, including a fish-processing plant, a hospital and a school, before meeting Sakhalin regional governor Valery Limarenko.
Russian state media and Kremlin footage showed the president examining local fish products and sampling fish roe during his visit to the island. The trip was presented by Moscow as part of the Russian government’s efforts to develop the country’s Far Eastern territories and promote economic activity in the region. (Reuters)
Putin also used the occasion to reaffirm Moscow’s position on the sovereignty question.
According to reports from the visit, the Russian leader argued that the status of the islands was established in the aftermath of World War II and rejected the premise that Russia’s control over the territory should be reconsidered. At the same time, he said Moscow had historically remained open to improving relations with Japan. (AP News)
The visit consequently delivered two messages at once: Russia intends to maintain its territorial position, while Moscow continues to leave some space rhetorically for broader relations with Tokyo.
Tokyo describes visit as unacceptable
Japan responded strongly to the visit.
Prime Minister Sanae Takaichi described Putin’s presence on the disputed islands as “absolutely unacceptable”, according to Reuters, reflecting Tokyo’s longstanding position that the territories are Japanese sovereign territory. (Reuters)
Japanese officials also lodged a formal protest through diplomatic channels.
The reaction illustrates the continuing sensitivity surrounding the islands in Japan, where the Northern Territories issue has retained political and historical significance for generations.
Tokyo’s position is that Iturup, Kunashir, Shikotan and the Habomai islets are Japanese territory illegally occupied by the Soviet Union at the end of World War II.
Moscow rejects that interpretation and maintains that Russian sovereignty over the islands is supported by the post-war international settlement.
The two positions have remained fundamentally incompatible, making the territorial dispute one of the principal unresolved issues between the two countries.
A dispute rooted in the final stages of World War II
The modern dispute centres on events in August 1945, when Soviet forces moved into the Kuril Islands after Japan announced its surrender.
The Soviet Union subsequently took control of the four islands that Japan now calls the Northern Territories.
Japan has continued to demand their return, while Russia has maintained sovereignty over them.
The territorial disagreement became closely linked to the absence of a formal peace treaty between Moscow and Tokyo following World War II.
Although the two countries normalised diplomatic relations in 1956, they never completed a comprehensive peace settlement resolving the territorial question.
Over the decades, successive Japanese and Russian governments have attempted to find a compromise, but negotiations have repeatedly stalled.
One of the most notable diplomatic efforts centred on the 1956 Soviet-Japanese Joint Declaration, which envisaged the possible transfer of Shikotan and the Habomai islets after the conclusion of a peace treaty. However, Japan continued to seek a broader resolution involving all four disputed territories.
Putin’s visit comes amid deteriorating bilateral relations
The latest development comes at a particularly difficult moment in Russia-Japan relations.
Tokyo joined Western countries in imposing sanctions on Moscow following Russia’s full-scale invasion of Ukraine in 2022. Russia subsequently suspended peace treaty negotiations with Japan and introduced countermeasures against Tokyo.
The deterioration in relations has also been accompanied by increased Russian military activity around the Kuril Islands.
Japan has expressed concern over Russia’s military deployments and exercises in the area, particularly because of the islands’ proximity to Hokkaido and their strategic location between the Pacific Ocean and the Sea of Okhotsk.
The Kuril chain provides Russia with important access routes into the Pacific and has considerable strategic significance for the Russian Pacific Fleet.
Analysts have therefore viewed the territorial dispute not only through the lens of historical sovereignty but also in the context of wider military and geopolitical competition in the Asia-Pacific region.
Strategic importance extends beyond territory
The Kuril Islands are strategically significant because of their geographical position.
The chain stretches between Russia’s Kamchatka Peninsula and Japan’s northern island of Hokkaido, creating a natural maritime corridor linking the Sea of Okhotsk with the Pacific Ocean.
Control of the islands therefore carries implications for naval access, fisheries, maritime boundaries and military operations.
Russia has strengthened its military presence in the region over the past decade, including the deployment of coastal defence systems and increased military exercises.
Japan, meanwhile, has been strengthening its defence capabilities as it confronts a wider set of security concerns involving Russia, China and North Korea.
The territorial dispute consequently exists within a broader regional security environment that has become increasingly competitive.
Russia’s position hardened after Ukraine sanctions
The relationship between Moscow and Tokyo deteriorated significantly after Japan joined the US and European countries in imposing sanctions on Russia.
Moscow has repeatedly criticised Japan’s participation in those measures.
Putin’s latest comments reportedly reflected this deterioration, with the Russian president indicating that relations had worsened because of Japan’s sanctions policy.
Nevertheless, he also maintained that Russia remained interested in cooperation with countries in the region, including Japan. (AP News)
That dual message is consistent with Moscow’s broader approach to its relationship with Tokyo: rejecting Japan’s territorial demands while leaving open the possibility of economic and diplomatic engagement where interests overlap.
Timing adds further political significance
The timing of Putin’s visit is also noteworthy.
The trip occurred just days before Japan’s annual August 15 commemoration marking the country’s surrender in World War II.
That historical timing gives the visit additional sensitivity in Japan, where the end of the war remains deeply connected to the Northern Territories question.
The visit also came amid heightened security concerns in the wider region, including a recent North Korean missile launch and ongoing military activity involving major regional powers. Reuters reported that the regional security environment had become increasingly tense, adding another layer of geopolitical significance to Putin’s trip. (Reuters)
For Tokyo, therefore, the visit is not simply a bilateral territorial disagreement. It is unfolding against a backdrop of broader concerns about Russia’s military posture and the changing balance of power in the Indo-Pacific.
The diplomatic dispute remains unresolved
Despite decades of negotiations, there is little indication that the territorial disagreement will be resolved in the immediate future.
Russia’s position is that the post-war territorial settlement established its sovereignty over the islands.
Japan maintains that the four disputed territories were unlawfully occupied and continues to demand their return.
The gulf between the two positions has widened since Russia’s invasion of Ukraine.
Before the deterioration of relations, Japan and Russia had explored economic cooperation on the disputed islands as a possible confidence-building measure.
Those initiatives have largely faded as diplomatic relations have deteriorated.
The result is a territorial dispute that remains frozen while military and political tensions continue to evolve.
Implications for Japan’s regional security policy
For Japan, the latest Russian move could reinforce arguments for maintaining a strong defence posture in its northern regions.
Tokyo is already pursuing a broader defence strategy designed to respond to threats across multiple fronts, including China’s growing military capabilities and North Korea’s missile programme.
Russia’s increased military activity around the Northern Territories adds another dimension to Japan’s security calculations.
The government must therefore balance its historical claim to the islands with the practical realities of managing relations with a nuclear-armed neighbour.
The diplomatic protest against Putin’s visit demonstrates that Japan has no intention of abandoning its sovereignty claim, even as the broader relationship with Moscow remains severely strained.
Wengglobal’s assessment
Putin’s first visit to the disputed Kuril Islands represents a significant symbolic development in one of East Asia’s longest-standing territorial disputes.
The visit does not change the underlying legal and political positions of either Russia or Japan, but it reinforces Moscow’s determination to maintain control of the islands and signals that the territorial issue remains firmly embedded in Russia’s strategic outlook for the Far East.
For Japan, the visit is a reminder that the Northern Territories dispute remains unresolved and that prospects for a comprehensive peace treaty with Russia are increasingly remote under current conditions.
The immediate consequence is likely to be further diplomatic friction rather than direct military confrontation.
Yet the wider implications are important.
With Russia strengthening its military position in the Pacific, Japan expanding its defence capabilities and China and North Korea adding further pressure to the regional security environment, the Kuril Islands dispute is no longer simply a historical disagreement over territory.
It is increasingly part of a broader contest over security, maritime access and strategic influence in the Indo-Pacific.
For Tokyo and Moscow, the challenge remains finding a diplomatic pathway through a dispute shaped by the legacy of World War II and intensified by the geopolitical divisions of the present.
For now, Putin’s arrival on Iturup has demonstrated that the issue remains far from settled.
