Putin’s Kurils visit provokes Tokyo

What's happened

Russian president Vladimir Putin has visited Iturup (Etorofu) in the disputed Kuril Islands, watched Pacific Fleet drills and toured local facilities. Japan has summoned the Russian ambassador and Prime Minister Sanae Takaichi and Foreign Minister Toshimitsu Motegi have called the visit unacceptable, saying the islands are Japan’s territory under history and international law.

What's behind the headline?

What this move signals

• Putin has travelled to Iturup while Russia’s Pacific Fleet is conducting live-fire drills. That shows Moscow is prioritising a visible military and political presence in the islands.

Diplomatic impact

• Japan has summoned Moscow’s ambassador and labelled the visit "absolutely unacceptable." That will harden Tokyo’s rhetoric and make short-term rapprochement on a peace treaty impossible.

Strategic consequences

• The islands provide air and naval basing and access to rich fishing and mineral resources; Russia is reinforcing those advantages by staging drills and hosting senior leadership visits. This will increase security tensions around Hokkaido and the north Pacific.

Forecast

• Tokyo will increase diplomatic pressure and is likely to sustain protests and formal complaints. Russia will continue integrating the islands into regional defence postures. The dispute will therefore remain a barrier to bilateral warming and will complicate wider security cooperation in the Asia–Pacific.

How we got here

The four southernmost Kuril islands were seized by the Soviet Union in 1945 and remain administered by Russia. Tokyo has long claimed them as the Northern Territories. The dispute has prevented a formal peace treaty since World War II and has resurfaced amid stronger Russian military activity and Tokyo’s new defence white paper.

Our analysis

The Guardian reports that Russia’s Pacific fleet has fired Bastion surface-to-ship missiles from Etorofu and that the drills include submarines and guided-missile cruisers; it quotes Japan’s foreign minister saying the moves "go against our country’s stance" (The Guardian, 21 Aug 2026). Al Jazeera described Putin’s itinerary — a fish-processing plant, hospital and school on Iturup — and quoted Prime Minister Sanae Takaichi calling the visit "absolutely unacceptable" (Al Jazeera, 13 Aug 2026). Politico and The Moscow Times cited Foreign Minister Toshimitsu Motegi’s X post: "The Northern Territories... are inherently Japanese territory both historically and under international law" (Politico, 13 Aug 2026; The Moscow Times, 13 Aug 2026). The Japan Times editorial context and reporting highlight Tokyo’s caution over responses because of concerns about energy supplies and broader security ties, and note the new defense white paper warning that Japan’s security environment "is as severe and complex as it has ever been" (The Japan Times, 14 & 21 Aug 2026). CNBC noted Putin’s visit followed inspection of Russian facilities and reported Tokyo’s strong protest and links to the defense white paper (CNBC, 14 Aug 2026). These accounts converge on the facts of the visit and Japan’s strong protest; reporting differs in emphasis, with Russian and Western outlets focusing respectively on Kremlin messaging and on diplomatic fallout and regional security consequences.

• Could this visit freeze any remaining talks over a Russia–Japan peace treaty?

  The Kuril Islands or Kurile Islands are a volcanic archipelago administered as part of Sakhalin Oblast in the Russian Far East. The islands stretch approximately 1,300 km (810 mi) northeast from Hokkaido in Japan to Kamchatka Peninsula in Russia, separating the Sea of Okhotsk from the north Pacific Ocean. There are 56 islands and many minor islets. The Kuril Islands consist of the Greater Kuril Chain and, at the southwest end, the parallel Lesser Kuril Chain. The group termed the 'South Kurils' consists of those of the Lesser Kuril Chain together with Kunashir and Iturup in the Greater Kuril Chain. The Vries Strait between Iturup and Urup forms the Miyabe Line dividing the North and South Kurils. The Kuril Islands cover an area of around 10,503.2 square kilometres (4,055.3 sq mi), with a population of roughly 20,000. The islands have been under Russian administration since their 1945 invasion by the Soviet Union near the end of World War II. Japan claims the four southernmost islands, including two of the three largest (Iturup and Kunashir), as part of its territory, as well as Shikotan and the unpopulated Habomai islets, which has led to the ongoing Kuril Islands dispute.
