Imagine you have a big argument with your neighbor over a piece of land. You both claim it's yours, but you can't agree on who gets it. That's kind of like the situation between Japan and Russia over the Kuril Islands. Japan thinks the islands belong to them, but Russia says they're theirs. The argument has been going on for a long time, and it's making it hard for the two countries to be friends.

Putin's Visit to the Kuril Islands: A Sobering Reality Check for Japan-Russia Relations
Russian President Vladimir Putin's visit to the disputed Kuril Islands has triggered a strong reaction from Japan, adding another strain to already tense relations between Tokyo and Moscow. The visit, which was Putin's first to the Kuril Islands as Russian president, has further hardened Japanese public sentiment toward Russia.
The dispute over the Kuril Islands dates back to the final days of World War II, when the Soviet Union seized the islands from Japan in 1945. Japan claims the four southernmost islands — Iturup, Kunashir, Shikotan, and the Habomai islets — and refers to them collectively as the Northern Territories. The territorial dispute has remained unresolved for decades and has prevented Russia and Japan from formally concluding a peace treaty ending their World War II hostilities.
Putin's visit to the Kuril Islands was a sovereign decision of the Russian leadership, and Moscow rejects Japan's territorial claim. The Russian Embassy in Japan called Tokyo's protest 'unfounded' and said the southern Kuril Islands were an integral part of the Russian Federation following World War II.
Despite defending Russia's position, Putin said Moscow remained prepared to seek a solution aimed at concluding a peace treaty with Japan. However, relations have deteriorated sharply since Russia launched its full-scale war in Ukraine in 2022. Japan joined other G7 nations in imposing sanctions on Russia after its invasion of Ukraine and has provided financial and non-lethal defense assistance to Kyiv.
The deterioration in bilateral ties has complicated efforts to resolve the Kuril Islands dispute and reach a peace treaty. The Kuril Islands are strategically important due to their rich fishing grounds and mineral resources, as well as their location giving them major military and strategic importance. Russia has strengthened its military presence on the islands, including deploying Bastion coastal defense missile systems and Su-35 fighter aircraft.
The military infrastructure gives Moscow greater control over regional sea lanes and reinforces its position in the territorial dispute. The visit has further complicated efforts to repair Japan-Russia relations, which have been strained since Russia launched its full-scale war in Ukraine in 2022.
