# Habomai Islands

The Habomai Islands (Japanese: 歯舞群島, romanized: Habomai guntō; Russian: Хабомаи, romanized: Khabomai) are a group of uninhabited islets (but for the Russian guards stationed there) in the southernmost Kuril Islands.
The islands have been under Soviet/Russian administration since the 1945 invasion by the Soviet Union near the end of World War II. But together with Iturup (Etorofu), Kunashir (Kunashiri), and Shikotan, the islands are claimed by Japan.

## History

In the seventeenth century the Matsumae clan made efforts to administer the islands; by 1644 the islands had been mapped as Japanese territories.
In 1732 the islands were mapped during the Russian Great Eastern Expedition.
The Treaty of Shimoda, signed by Russia and Japan in 1855, recognised Japanese ownership of Iturup, Kunashir, Shikotan, and the Habomai Islands.
The Habomai Islands were occupied by Soviet forces in the last few days of World War II. The islands were eventually annexed by the Soviet Union, which deported all the island residents to Japan. Moscow claimed the islands as part of a war-time agreement between the Allies (Yalta Agreement), which provided for the transfer of the Chishima (Kurile) Islands to the USSR in return for its participation in the Pacific War. However, Japan maintains that the Habomai Islands are not part of the Kuriles and are in fact part of Hokkaido prefecture. On May 26, 1955, the United States submitted an application for proceedings against the Soviet Union. As part of the proceedings, the United States questioned the validity of the Soviet Union's claim to the Habomai Islands.
In 1956, after difficult negotiations, the Soviet Union agreed to cede the Habomai to Japan, along with Shikotan, after the conclusion of a peace treaty between the two countries. As the treaty was never concluded, the islands remained under Soviet jurisdiction. However, the promise of a two-island solution (for the purpose of simplicity, the Habomai rocks count as one island) has been renewed in the Soviet-Japanese, and later Russo-Japanese negotiations. Formerly home to a Japanese fishing community, the islands are now uninhabited except for the Russian border guard outpost.
