Russian President Vladimir Putin recently visited Iturup, one of the Kuril Islands, sparking a strong rebuke from Japan. The islands are claimed by both Russia and Japan, a dispute dating back to the end of World War II. Tokyo condemned the visit as “absolutely unacceptable,” highlighting the ongoing tensions over the territory. This marks Putin’s first trip to the islands, a move seen as a demonstration of Russian sovereignty. Japan maintains its claim to the four islands, referring to them as the Northern Territories. The visit is likely to further complicate diplomatic relations between the two countries, hindering potential progress in resolving the longstanding territorial dispute. It underscores Russia’s firm stance on the issue and its control over the islands.
