The long-running dispute over the Kuril Islands remains a barrier to a full political settlement between Russia and Japan. BBC World Service programming scheduled for October 20 is examining whether an agreement is possible, although the prospects are constrained by broader strategic tensions.
The dispute concerns islands controlled by Russia but claimed by Japan. The disagreement has prevented the two countries from signing a formal peace treaty ending the legal state of war left over from the Second World War. For decades, negotiations have focused on sovereignty, access arrangements and the possibility of transferring some islands or creating joint economic activity.
The issue is important because the islands sit in a strategically sensitive area between the Pacific Ocean and the Sea of Okhotsk. They are linked to fishing grounds, maritime routes and Russia’s wider military posture in the Far East. Japan’s position is also shaped by domestic politics and its alliance relationship with the United States.
The geopolitical environment has made progress more difficult. Russia’s relations with Japan deteriorated after Tokyo joined sanctions and other measures against Moscow following the invasion of Ukraine. Moscow suspended some negotiations, while military activity and security cooperation in the region increased.
Any future settlement would require more than a bilateral compromise. It would need to address security guarantees, fishing rights, movement between communities and the practical administration of territory. Economic cooperation could create confidence, but it could also be constrained by sanctions and competing strategic interests.
The dispute illustrates how unresolved historical questions can remain relevant to current security policy. Territorial disagreements often affect military planning, resource access and national identity long after the original conflict has ended.
A breakthrough does not appear imminent based on the present political environment. Yet the issue remains important because changes in Russia–Japan relations could influence the broader security balance in Northeast Asia and the management of maritime resources.
