Japanese administration

At the very end of the 19th century, the Japanese administration started the forced assimilation of the native Ainu people. Also at this time the Ainu were granted automatic Japanese citizenship, effectively denying them the status of an indigenous group. Many Japanese moved onto former Ainu lands, including the Kuril islands. The Ainu required to adopt Japanese names, and ordered to cease religious practices such as animal sacrifice and the custom of tattooing. Although not compulsory education, education was conducted in Japanese. Prior to Japanese colonization (in 1868) about 100 Ainu reportedly lived on the Kuril islands.

These include ethnic Russians, Ukrainians, Belarusians, Tatars, Nivkh people, Nivkhs, Oroch people, Oroch, and Ainu in Russia, Ainus.

following recent tensions). Others are inhabited by civilians, which are mostly fishers, workers in fish factories, dockers, and social sphere workers (police, medics, teachers, etc.). Recent construction works on the islands attracts a lot of migrant workers from the rest of Russia and other post-Soviet states. , there were only 8 inhabited islands out of a total of 56. Iturup Island is over 60% ethnically Ukrainian.


Economy

Fishing is the primary occupation. The islands have strategic and economic value, in terms of fisheries and also mineral deposits of pyrite, sulfur, and various polymetallic ores. There are hopes that oil exploration will provide an economic boost to the islands. In 2014, construction workers built a pier and a breakwater in Kitovy Bay, central Iturup, where barges are a major means of transport, sailing between the cove and ships anchored offshore. A new road has been carved through the woods near Kurilsk, the island's biggest village, going to the site of Yuzhno-Kurilsk Mendeleyevo Airport. Gidrostroy, the Kurils' biggest business group with interests in fishing, construction and real estate, built its second fish processing factory on Iturup island in 2006, introducing a state-of-the-art conveyor system. To deal with a rise in the demand of electricity, the local government is also upgrading a state-run geothermal power plant at Baransky, Mount Baransky, an active volcano, where steam and hot water can be found.


Military

The main Russian force stationed on the islands is the 18th Machine Gun Artillery Division, which has its headquarters in Goryachiye Klyuchi on Iturup Island. There are also Border Guard Service troops stationed on the islands. In February 2011, Russian President Dmitry Medvedev called for substantial reinforcements of the Kuril Islands defences. Subsequently, in 2015, additional anti-aircraft missile systems Tor missile system, Tor and Buk missile system, Buk, Coastal defence and fortification, coastal defence missile system Bastion, Kamov Ka-50, Kamov Ka-52 combat helicopters and one Kilo-class submarine, ''Varshavyanka'' project submarine came on defence of Kuril Islands. During the 2022 Russian Invasion of Ukraine it was reported that parts of the 18th Machine Gun Artillery Division were redeployed to Eastern Ukraine.


List of main islands

While in Russian sources the islands are mentioned for the first time in 1646, the earliest detailed information about them was provided by the explorer Vladimir Atlasov in 1697. In the 18th and early 19th centuries, the Kuril Islands were explored by Danila Antsiferov, I. Kozyrevsky, Ivan Yevreinov, Fyodor Luzhin, Martin Shpanberg, Adam Johann von Krusenstern, Vasily Golovnin, and Henry James Snow.
