Putin’s First Visit to Japan-Claimed Kuril Island Sparks Strong Protest From Tokyo

Moscow/Tokyo, August 13, 2026 — Russian President Vladimir Putin has made his first reported personal visit to the disputed Kuril Islands, travelling to Iturup, an island controlled by Russia but claimed by Japan as part of its Northern Territories. The visit has triggered a strong diplomatic reaction from Tokyo and placed the long-running territorial dispute between the two countries back in the international spotlight.

Putin’s appearance on Iturup comes at a particularly sensitive moment for security in the wider Asia-Pacific region. The Russian leader’s trip followed major military activity involving Russia’s Pacific Fleet, while North Korea also carried out a missile launch. The combination of the presidential visit, military exercises and heightened regional tensions has given the development significance beyond the territorial dispute itself.

Putin Visits Iturup

According to Russian media reports, Putin travelled to Iturup, known as Etorofu in Japan, during a wider trip through Russia’s Far East. The island is one of the four southern islands that Japan claims as its own and calls part of the Northern Territories.

During his visit, Putin toured a local fish-processing facility, visited public institutions and met local officials and residents. He also inspected Russian military activity in the broader Far Eastern region.

The visit is notable because, although other senior Russian officials have travelled to the disputed islands in previous years, Putin himself had not previously made such a visit. His decision to go there personally gives the trip additional political weight.

Moscow administers the islands and regards them as Russian territory. Japan disputes that position and continues to demand the return of the four southern islands: Iturup, Kunashir, Shikotan and the Habomai island group.

Japan Lodges Strong Protest

Tokyo responded sharply to Putin’s visit.

Japanese Foreign Minister Toshimitsu Motegi reiterated Japan’s position that the islands are an inherent part of Japanese territory. The Japanese government formally protested the Russian leader’s presence on Iturup, describing the visit as unacceptable from Tokyo’s perspective.

Japan has consistently regarded the Northern Territories issue as one of its most important unresolved territorial questions. The latest visit is therefore likely to reinforce political pressure within Japan for a firm response to Moscow.

The dispute has remained unresolved for decades and has complicated broader relations between Russia and Japan.

A Dispute Dating Back to World War II

The roots of the disagreement stretch back to the final stages of World War II.

Soviet forces took control of the Kuril Islands in 1945 as Japan was defeated. Japan subsequently maintained its claim to the four southern islands, while Russia inherited administrative control following the dissolution of the Soviet Union.

The disagreement became one of the central reasons Moscow and Tokyo never concluded a formal post-World War II peace treaty. The territorial question has repeatedly prevented the two governments from completely normalizing relations.

Japan refers to the disputed islands as the Northern Territories, while Russia treats them as part of its Sakhalin region.

The two countries have held numerous negotiations over the decades, but none has produced a final settlement acceptable to both sides.

Why Iturup Matters

Iturup is the largest of the four islands claimed by Japan and occupies a strategically important position in the northern Pacific.

The island lies between the Pacific Ocean and the Sea of Okhotsk and forms part of the chain stretching toward Russia’s Kamchatka Peninsula. Its location gives the broader Kuril chain considerable military and maritime importance.

The waters surrounding the islands are also rich in marine resources, particularly fisheries. Economic activity on the islands includes fishing and seafood processing, sectors that Putin highlighted during his visit.

For Moscow, maintaining infrastructure and economic activity in the region helps demonstrate its effective administration of the islands. For Tokyo, continued Russian development and military activity there are viewed as evidence that Moscow is strengthening its presence in territory Japan continues to claim.

Military Context Raises the Stakes

Putin’s visit did not occur in isolation.

Before travelling to Iturup, the Russian president was involved in activities connected with Russia’s Pacific Fleet. Russian military exercises were being conducted in the Far East, including naval activity around Sakhalin.

The timing has attracted attention because North Korea also launched a ballistic missile around the same period.

The combination of Russian naval exercises, Putin’s visit to the disputed islands and North Korean missile activity highlights the increasingly complicated security environment in Northeast Asia.

Japan is closely aligned with the United States and South Korea on regional security issues, while Russia has strengthened its strategic relationship with North Korea. Moscow’s growing military and political engagement in the region is therefore being watched closely by Tokyo.

Russia’s Strategic Message

Putin’s decision to visit Iturup can be interpreted as a strong demonstration of Russia’s position that the southern Kuril Islands are under its sovereignty.

A presidential visit carries a different symbolic impact from a statement issued by government officials. By physically travelling to the island and meeting people there, Putin has projected an image of Russian administrative control.

The trip also comes at a time when Russia’s relations with Japan have deteriorated significantly because of the broader geopolitical confrontation surrounding the war in Ukraine.

Japan has joined Western sanctions against Moscow, while Russia has criticized Tokyo’s policies and placed Japan among countries it considers unfriendly.

Under those circumstances, expectations of a rapid breakthrough on the territorial issue have become increasingly low.

Japan-Russia Relations Under Pressure

The Kuril dispute has historically complicated economic and political cooperation between Moscow and Tokyo. At various points, both countries attempted to separate economic relations from the territorial disagreement.

There were periods when negotiations appeared more promising, including discussions over possible economic cooperation on the disputed islands. However, geopolitical tensions have repeatedly undermined those efforts.

The Ukraine conflict further damaged the relationship. Japan’s alignment with Western sanctions made negotiations more difficult, while Moscow subsequently suspended or abandoned several initiatives involving Tokyo.

Putin’s latest visit could make diplomatic engagement even harder.

Wider Regional Implications

The significance of the visit extends beyond Russia and Japan.

The Kuril chain sits close to major sea routes linking Northeast Asia with the northern Pacific. Russia’s military presence in the region is therefore relevant to the strategic calculations of Japan, the United States and other regional powers.

Japan has been increasing its attention to security around its northern and southwestern approaches, while Russia has sought to reinforce its Far Eastern military capabilities.

At the same time, China-Russia relations and Russia-North Korea cooperation have become increasingly important factors in the region’s strategic balance.

Against this backdrop, any high-profile Russian activity around the disputed islands is likely to attract greater attention than it might have several years ago.

What Happens Next?

The immediate consequence of Putin’s visit is likely to be another period of diplomatic tension between Moscow and Tokyo.

Japan is expected to continue emphasizing its territorial claim, while Russia is unlikely to signal any willingness to surrender control over the islands.

The absence of a peace treaty between the two countries means the territorial issue will remain an unresolved element of their relationship.

For now, Putin’s trip sends a clear political message: Moscow intends to maintain its authority over the disputed territory and continue developing the Russian Far East.

For Tokyo, however, the visit represents another challenge to its longstanding claim over the Northern Territories.

The episode demonstrates that a dispute originating in the final days of World War II continues to influence diplomacy and security in Northeast Asia more than eight decades later. With military activity increasing across the region, the Kuril question is likely to remain an important source of tension between Russia and Japan.
