Key Points
Putin visited Etorofu Island, the largest of four disputed Kuril Islands claimed by Japan, for the first time on August 13.
Japan's Prime Minister Sanae Takaichi called the visit 'absolutely unacceptable' and said it offends Japanese sentiments.
The Soviet Union seized the islands in 1945, deporting 17,000 Japanese residents; roughly 20,000 Russians now live there.
Russia-Japan relations deteriorated after Japan joined Western sanctions over Putin's 2022 invasion of Ukraine.
Russian President Vladimir Putin visited Etorofu, the largest of four disputed islands off Hokkaido, on Thursday, drawing an immediate “strong protest” from Tokyo. Prime Minister Sanae Takaichi called the visit “absolutely unacceptable” and said it offends Japanese sentiments. The islands, seized by the Soviet Union in 1945 and known in Japan as the Northern Territories, remain a core obstacle to a formal peace treaty between the nations.
Why Putin’s visit matters now
Putin’s trip marks the first time a sitting Russian president has visited the contested Kuril Islands. Former President Dmitry Medvedev visited in 2010, but Putin’s visit carries greater symbolic weight. The timing is deliberate: it comes two days before Japan marks 81 years since its World War II surrender and amid heightened regional tensions involving North Korea missile tests.
Japan’s formal response and diplomatic fallout
Japan’s Foreign Minister Toshimitsu Motegi issued a statement declaring the islands “an inherent part of Japan’s territory both historically and under international law.” Prime Minister Takaichi told reporters the visit “offends the sentiments of the Japanese people and is absolutely unacceptable.” Tokyo summoned the Russian ambassador to lodge a formal protest.
The unresolved territorial dispute
The Soviet Union seized the four islands in the final days of World War II, deporting approximately 17,000 Japanese residents. Today, roughly 20,000 Russian citizens inhabit the islands. The unresolved dispute has prevented Moscow and Tokyo from signing a formal peace treaty, blocking closer economic ties. Russia and China’s ambassadors to Japan issued a joint statement on Thursday opposing any revision of World War II outcomes.
How Ukraine sanctions worsened the rift
Russia-Japan relations deteriorated sharply after Putin’s 2022 invasion of Ukraine. Japan joined Western nations in condemning the attack and imposing sanctions on Russia. Putin, speaking from a warship during Pacific Fleet exercises on Wednesday, said Japan imposed sanctions “in no way provoked by us” and claimed Russia has “absolutely no claims” against Japan, while reaffirming Russia’s control of the islands.
Putin’s broader Pacific strategy
Putin visited the islands after overseeing Russian Pacific Fleet naval drills near Sakhalin. During those exercises, he threatened retaliation against Western nations seizing Russian commercial vessels used to evade Ukraine sanctions. He said Russia would respond “not necessarily in the waters where they plan to raid our own ships but anywhere we consider necessary or reasonable, including in the Pacific Fleet’s area of responsibility.”
Final Thoughts
Putin’s visit signals Moscow’s hardening stance on the Northern Territories and reflects deteriorating Russia-Japan ties. With no peace treaty signed and territorial claims unresolved, the diplomatic rift will likely persist as long as sanctions remain in place.
