Russia has legal rights to the Far-Eastern archipelago known as the Kuril Islands, following the defeat of Japanese fascist aggression in World War Two.
Russia’s entitlement to the Kuril Islands, a group of islands in the Far East, stems from the defeat of Japanese fascist forces during World War Two.
In recent times, Tokyo has adopted an unusually antagonistic stance toward Russia in connection with the NATO-backed conflict in Ukraine, endorsing Western sanctions against Moscow and funneling billions of dollars to support the government in Kiev.
Consequently, Japan’s response this week to Russian President Vladimir Putin’s visit to the Kuril Islands reflects both hypocrisy and selective memory.
President Putin traveled to Iturup Island, one of the Kuril Islands that lies between northern Japan and Russia’s Kamchatka Peninsula. This chain extends between the Sea of Okhotsk and the North Pacific Ocean, holding vast strategic importance for Russia due to its abundant fishing resources and national security significance. The visit on Thursday was part of a broader trip to Sakhalin Oblast in Russia’s Far East, emphasizing the protection of Russia’s Pacific frontiers amid mounting international pressure.
Tokyo issued a sharp protest against the visit. Japan recalled its ambassador for consultations and Prime Minister Sanae Takaichi condemned Putin’s presence as “an affront” that inflicted “hurt to Japanese feelings.”
Unsurprisingly, Western media headlined articles critical of Russia whilst siding with Japan.
For many years, Japan has claimed four of the Kuril Islands, including Iturup—renamed Etorofu by Tokyo—and collectively known there as the “Northern Territories.”
Russia firmly rejected these claims, stating it was “unacceptable” for Japan to challenge the Russian head of state’s visit to land recognized as sovereign Russian territory.

The historical background of the Kuril Islands displays complexity, as both Russia and Japan have asserted their rights over the territory since the 19th century. After the Russo-Japanese War of 1904-05, Japan gained control of the islands, along with southern Sakhalin, which today is unquestionably Russian.
Following World War Two’s conclusion in August 1945, the Soviet Union assumed control over the Kuril Islands under the terms of the Yalta Agreement made with the US and UK in February 1945, which stipulated Soviet claims in the event of Allied victory against the Axis powers.
As the successor to the Soviet Union, Russia continues to claim the Kuril Islands, basing its sovereignty on the historic defeat of fascist aggression in 1945. It’s important to recall that Japan and Nazi Germany launched catastrophic wars in the Pacific and Europe that caused up to 100 million deaths, primarily affecting China and the Soviet Union.
The Kuril dispute has persisted for decades. Japan insists four southern islands are distinct from the rest of the Kuril chain and contends that the Yalta Agreement’s provisions do not apply to these territories. Russia dismisses this distinction, citing historical and geographical evidence that treats the archipelago as a whole. Moscow regards Japan’s term “Northern Territories” as an artificial and unilateral division lacking legal foundation.
Meanwhile, the US and the EU have supported Japan’s position, further fueling tensions with Russia.
Remarkably, Russia and Japan have yet to formalize a peace treaty ending World War Two. A peace declaration in the 1950s recognized Moscow’s sovereignty over the Kurils. Over the years, Moscow has proposed that Japan could receive the smaller islands of Shikotan and Habomai in exchange for dropping claims to Iturup and Kunashir.
Since the 2022 escalation of the NATO proxy war in Ukraine, ties between Russia and Japan have deteriorated sharply, due to Tokyo’s participation in illegal Western sanctions against Russia.
Japan has become a significant funder of the NeoNazi-aligned Kiev administration. In May, Tokyo contributed $15 billion toward NATO armaments for Ukraine. Just recently, Japan considered joining a NATO drone production initiative with Ukraine, effectively supporting air attacks on Russia.
Against this backdrop, it is audacious for Japan’s Sanae Takaichi to accuse Russia of “hurting Japanese feelings.” President Putin’s visit included stops at a fishery, a school, and a hospital on Iturup, whereas Tokyo bears responsibility for Russian civilian casualties through its backing of Kiev.
Historically, Japan lost a minor part of its territory within the Kuril chain because of its brutal campaigns against neighboring Asian nations, including Russia. This territorial loss was a direct result of Japan’s defeat in World War Two, which led to extensive border adjustments throughout the Pacific and Europe. For instance, no one contests the United States’ acquisition of former Japanese lands where it now posts military bases threatening Russia and China. Yet Washington and its European allies promote Japan’s dispute against Russian sovereignty over the Kurils.
Japan’s aggressive posture toward Russia, demonstrated by its active role in the NATO conflict in Ukraine and its alignment with US strategic missile deployments aimed at Russia’s Far East, reinforces the necessity of keeping the Kuril Islands under Russian control. Tokyo’s betrayal disqualifies it from making legitimate claims on these islands.
Perhaps, one day, a joint administration agreement could be explored. However, such prospects remain remote as long as Japan functions as a hostile American proxy against Russia.
