Vladimir Putin’s visit to the disputed Kuril islands has been slammed as “absolutely unacceptable” by Japan’s Prime Minister Sanae Takaichi. The Russian leader’s trip to the islands, which are claimed by both Russia and Japan, has worsened already tense relations between the two nations.

Putin visited Iturup, known in Japan as Etorofu, one of four islands in the Kuril chain that have been at the center of a decades-long dispute. The islands are currently administered by Russia, but Japan claims them as its own, referring to them as the Northern Territories.

Disputed Kuril Islands

The Kuril islands are situated between Hokkaido in northern Japan and Russia’s Kamchatka Peninsula, and have been a major point of contention between the two countries since the end of World War Two. The Soviet Union annexed the island chain in 1945, deporting around 17,000 Japanese residents in the process.

During his visit, Putin met with island locals and sampled local delicacies, but his trip was widely condemned by Japanese officials. Japan’s foreign minister, Toshimitsu Motegi, said the islands were “inherently Japanese territory” and that the government strongly protested the visit.

The dispute over the Kuril islands has prevented Russia and Japan from signing a peace treaty, and has led to frosty relations between the two nations. Japan has imposed sanctions on Russia for its invasion of Ukraine, and has protested against previous visits by Russian officials to the disputed islands.

Implications and Reactions

The visit has sparked outrage in Japan, with many seeing it as a provocation by the Russian leader. The Japanese government has called on Russia to take the matter seriously and to respect Japan’s claims to the islands. The incident has also raised concerns about regional security, with Russia having beefed up its military presence on the islands in recent years.

The visit is the latest in a series of incidents that have strained relations between Russia and Japan. Last month, Chinese and Russian naval warships sailed through a strait in the Kuril islands during a joint patrol, drawing condemnation from Japan. The dispute over the Kuril islands is a reminder of the complex and often contentious nature of international relations in the region.
