Why Russia and Japan have remained technically at war for nearly eighty years
In short: The Kuril Islands dispute is a lingering ghost of World War II. Despite decades of negotiations, Russia and Japan have never signed a formal peace treaty. At the heart of the deadlock is a cluster of islands that both nations claim, fueled by conflicting interpretations of post-war international agreements.
The conflict centers on four islands: Iturup, Kunashir, Shikotan, and the Habomai chain. These territories were annexed by the Soviet Union in the final days of World War II, following a 1945 invasion. While the 1951 Treaty of San Francisco required Japan to renounce its rights to the Kuril Islands, it failed to explicitly recognize Soviet sovereignty over them. Japan has since argued that the disputed islands are not part of the Kuril chain and thus remain outside the treaty's scope, a position Russia rejects.
Diplomatic efforts have repeatedly stalled. In 1956, the Soviet–Japanese Joint Declaration ended the state of war between the two nations and included a Soviet offer to return the two smaller islands, Shikotan and the Habomai Islands, upon the signing of a peace treaty. Japan initially accepted this compromise, but later hardened its stance to demand the return of all four islands. This shift, which some historians attribute to internal political pressure and external warnings from the United States, created a permanent stalemate that persists today.
The dispute remains a volatile feature of regional relations. Russia currently administers the islands as part of the Sakhalin Oblast, while Japan continues to assert its sovereignty through textbook guidelines and diplomatic protests. Tensions occasionally flare, such as during high-profile visits by Russian officials to the islands, which Tokyo has labeled as unacceptable. Despite ongoing economic interactions, including Japanese payments for fishing rights in the area, the lack of a definitive legal resolution ensures that the islands remain a symbol of unfinished post-war business.
