Kuril Islands: What to know about the islands at the centre of a territorial dispute between Russia and Japan
- The feud over a string of volcanic islands has prevented the two countries from signing a formal second world war peace treaty
- The islands are rich in hot springs and minerals and rare metals such as rhenium, which is used in the production of supersonic aircraft
Called the Kurils by Russia and the Northern Territories by Japan, a string of volcanic islands are at the heart of a feud between the two countries that has prevented them signing a formal World War II peace treaty.
Talks stalled for decades due to Japan’s claim to the four strategic islands seized by the Soviet army in the final days of the war. Here are some key facts about the Kuril Islands.
Location
The disputed islands of Iturup (Etorofu in Japanese), Kunashir (Kunashiri), Shikotan and Habomai lie at their closest point just a few kilometres off the north coast of Hokkaido in Japan. They are the southernmost islands in a volcanic chain that separates the Sea of Okhotsk and the Pacific Ocean.
They are located to the southeast of the Russian island of Sakhalin and are administratively part of the same region, although Tokyo considers them part of its Hokkaido prefecture and “illegally occupied by Russia”.

Treaties
Russian Empress Catherine the Great claimed sovereignty over the Kuril Islands in 1786 after her government declared they were discovered by “Russian explorers” and therefore “undoubtedly must belong to Russia”.
