The Kuril Islands or Kurile Islands (/ˈkʊərɪl/, /ˈkjʊərɪl/, or /kjʊˈriːl/; Russian: Кури́льские острова́, tr. Kurilskiye ostrova; IPA: [kʊˈrʲilʲskʲɪjə ɐstrɐˈva]; Japanese: Kuriru rettō (クリル列島, "Kuril Islands") or Chishima rettō (千島列島, "Chishima Islands")), in Russia's Sakhalin Oblast region, form a volcanic archipelago that stretches approximately 1,300 km (810 mi) northeast from Hokkaido, Japan, to Kamchatka, Russia, separating the Sea of Okhotsk from the North Pacific Ocean. There are 56 islands and many minor rocks. It consists of Greater Kuril Ridge and Lesser Kuril Ridge. The total land area is 10,503.2 square kilometres (4,055.3 sq mi) and the total population is 19,434.
All the islands are currently under Russian jurisdiction. Japan claims the two southernmost large islands (Iturup and Kunashir) as part of its territory, as well as Shikotan and the Habomai islets, which has led to the ongoing Kuril Islands dispute. The disputed islands are known in Japan as the country's "Northern Territories".
The name Kuril originates from the autonym of the aboriginal Ainu, the islands' original inhabitants: "kur", meaning man. It may also be related to names for other islands that have traditionally been inhabited by the Ainu people, such as Kuyi or Kuye for Sakhalin and Kai for Hokkaidō. In Japanese, the Kuril Islands are known as the Chishima Islands (Kanji: 千島列島 Chishima Rettō pronounced [t͡ɕiɕima ɾet̚toː], literally, Thousand Islands Archipelago), also known as the Kuriru Islands (Katakana: クリル列島 Kuriru Rettō [kɯɾʲiɾɯ̥ ɾet̚toː], literally, Kuril Archipelago). Once the Russians reached the islands in the 18th century they found a pseudo-etymology from Russian kurit ("курить" – "to smoke") due to the continual fumes and steam above the islands from volcanoes.
The Kuril Islands form part of the ring of tectonic instability encircling the Pacific Ocean referred to as the Ring of Fire. The islands themselves are summits of stratovolcanoes that are a direct result of the subduction of the Pacific Plate under the Okhotsk Plate, which forms the Kuril Trench some 200 kilometres (120 mi) east of the islands. The chain has around 100 volcanoes, some 40 of which are active, and many hot springs and fumaroles. There is frequent seismic activity, including a magnitude 8.5 earthquake in 1963 and one of magnitude 8.3 recorded on November 15, 2006, which resulted in tsunami waves up to 1.5 metres (5 ft) reaching the California coast.
The climate on the islands is generally severe, with long, cold, stormy winters and short and notoriously foggy summers. The average annual precipitation is 30–40 inches (760–1,020 mm), most of which falls as snow.
The chain ranges from temperate to sub-Arctic climate types, and the vegetative cover consequently ranges from tundra in the north to dense spruce and larch forests on the larger southern islands. The highest elevations on the islands are Alaid volcano (highest point: 2,339 m or 7,674 ft) on Atlasov Island at the northern end of the chain and Tyatya volcano (1,819 m or 5,968 ft) on Kunashir Island at the southern end.
Landscape types and habitats on the islands include many kinds of beach and rocky shores, cliffs, wide rivers and fast gravelly streams, forests, grasslands, alpine tundra, crater lakes and peat bogs. The soils are generally productive, owing to the periodic influxes of volcanic ash and, in certain places, owing to significant enrichment by seabird guano. However, many of the steep, unconsolidated slopes are susceptible to landslides and newer volcanic activity can entirely denude a landscape. Only the southernmost island has large areas covered by trees, while more northerly islands have no trees, or spotty tree cover.
Owing to their location along the Pacific shelf edge and the confluence of Okhotsk Sea gyre and the southward Oyashio Current, the Kuril islands are surrounded by waters that are among the most productive in the North Pacific, supporting a wide range and high abundance of marine life.
Invertebrates: Extensive kelp beds surrounding almost every island provide crucial habitat for sea urchins, various mollusks and countless other invertebrates and their associated predators. Many species of squid provide a principal component of the diet of many of the smaller marine mammals and birds along the chain.
Fish: Further offshore, walleye pollock, Pacific cod, several species of flatfish are of the greatest commercial importance. During the 1980s, migratory Japanese sardine was one of the most abundant fish in the summer and the main pinnipeds were a significant object of harvest for the indigenous populations of the Kuril islands, both for food and materials such as skin and bone. The long term fluctuations in the range and distribution of human settlements along the Kuril island presumably tracked the pinniped ranges. In historical times, fur seals were heavily exploited for their fur in the 19th and early 20th centuries and several of the largest reproductive rookeries, as on Raykoke island, were extirpated. In contrast, commercial harvest of the true seals and Steller sea lions has been relatively insignificant on the Kuril islands proper. Since the 1960s there has been essentially no additional harvest and the pinniped populations in the Kuril islands appear to be fairly healthy and in some cases expanding. The notable exception is the now extinct Japanese sea lion which was known to occasionally haul out on the Kuril islands.
Seabirds: The Kuril islands are home to many millions of seabirds, including northern fulmars, tufted puffins, murres, kittiwakes, guillemots, auklets, petrels, gulls and cormorants. On many of the smaller islands in summer, where terrestrial predators are absent, virtually every possibly hummock, cliff niche or underneath of boulder is occupied by a nesting bird.
The composition of terrestrial species on the Kuril islands is dominated by Asian mainland taxa via migration from Hokkaido and Sakhalin Islands and by Kamchatkan taxa from the North. While highly diverse, there is a relatively low level of endemism.
The WWF divides the Kuril Islands into two ecoregions. The southern Kurils, along with southwestern Sakhalin, comprise the South Sakhalin-Kurile mixed forests ecoregion. The northern islands are part of the Kamchatka-Kurile meadows sparse forests, a larger ecoregion that extends onto the Kamchatka peninsula and Commander Islands.
Because of the generally smaller size and isolation of the central islands, few major terrestrial mammals have colonized these, though red and Arctic foxes were introduced for the sake of the fur trade in the 1880s. The bulk of the terrestrial mammal biomass is taken up by rodents, many introduced in historical times. The largest southernmost and northernmost islands are inhabited by brown bear, foxes, and martens. Some species of deer are found on the more southerly islands. It is claimed that a wild cat, the Kurilian Bobtail, originates from the Kuril Islands. The bobtail is due to the mutation of a dominant gene. The cat has been domesticated and exported to nearby Russia and bred there, becoming a popular domestic cat.
The Ainu people were early inhabitants of Kuril Islands, although there are few records that predate the 17th century. The Japanese administration first took nominal control of the islands in the Edo period of Japan, in the form of claims by the Matsumae clan. It is claimed that the Japanese knew of the northern islands 370 years ago. On "Shōhō Onkuko Ezu", a map of Japan made by the Tokugawa shogunate, in 1644, there are 39 large and small islands shown northeast of the Shiretoko peninsula and Cape Nosappu.
Choka seems to have been the Ainu name for Paramushir and its neighbouring islands. Then Rakkoshima ("sea-otter isles") extended from Onnekotan to Shimushir. Urup, Iturup and Kunashir are the three southern islands.
In 1811, Russian Captain Vasily Golovnin and his crew, who stopped at Kunashir during their hydrographic survey, were captured by retainers of the Nambu clan, and sent to the Matsumae authorities. Because a Japanese trader, Takadaya Kahei, was also captured by Petr Rikord, Captain of a Russian vessel near Kunashir in 1812, Japan and Russia entered into negotiations to establish the border between the two countries.
American whaleships caught right whales off the islands between 1847 and 1892. Three of the ships were wrecked on the islands: two on Urup in 1855 and one on Makanrushi in 1856. In September 1892, the bark Cape Horn Pigeon, of New Bedford, was seized by a Russian schooner north of Kunashir Island and escorted to Vladivostok, where it was detained for nearly two weeks.
The Treaty of Commerce, Navigation and Delimitation was concluded in 1855, and the border was established between Iturup and Urup. This border confirmed that Japanese territory stretched south from Iturup and Russian territory stretched north of Urup. Sakhalin remained a place where people from both countries could live. The Treaty of Saint Petersburg in 1875 resulted in Japan relinquishing all rights over Sakhalin in exchange for Russia ceding all of the Kuril Islands south of Kamchatka.
During the Russo-Japanese War of 1904–1905, Gunji, a retired Japanese military man and local settler in Shumshu, led an invading party to the Kamchatka coast. Russia sent reinforcements to the area to capture and intern this group. After the war was over, Japan received fishing rights in Russian waters as part of the Russo-Japanese Fisheries Agreement until 1945.
During their armed intervention in Siberia 1918–1925, Japanese forces from the northern Kurils, along with United States and European forces, occupied southern Kamchatka. Japanese vessels made naval strikes against Petropavlovsk-Kamchatsky.
The Soviet Union conquered South Sakhalin and the Kuril islands at the end of World War II. Japan maintains a claim to the four southernmost islands of Kunashir, Iturup, Shikotan, and the Habomai rocks, together called the Northern Territories (see Kuril Islands dispute).
In 1869, the Meiji government established the Colonization Commission in Sapporo to aid in the development of the northern area. Ezo was renamed Hokkaidō and Kita Ezo later received the name of Karafuto. Eleven provinces and 86 districts were founded by Meiji government and were put under the control of feudal clans. Because the Meiji government could not sufficiently cope with Russians moving to south Sakhalin, Japan negotiated with Russia over control of the Kuril Islands, resulting in the Treaty of Saint Petersburg that ceded the eighteen islands north of Uruppu to Japan and all of Sakhalin to Russia.
Road networks and post offices were established on Kunashiri and Etorofu. Life on the islands became more stable when a regular sea route connecting islands with Hokkaidō was opened and a telegraphic system began. At the end of the Taishō period, towns and villages were organized in the northern territories and village offices were established on each island. The Habomai island towns were all part of Habomai Village for example. In other cases the town and village system was not adopted on islands north of Uruppu, which were under direct control of the Nemuro Subprefectural office of the Hokkaidō government.
Each village had a district forestry system, a marine product examination center, salmon hatchery, post office, police station, elementary school, Shinto temple, and other public facilities. In 1930, 8,300 people lived on Kunashiri island and 6,000 on Etorofu island, and most of them were engaged in coastal and high sea fishing.
As of 2013[update], 19,434 people inhabited the Kuril Islands. These include ethnic Russians, Ukrainians, Belarusians, Tatars, Nivkhs, Oroch, and Ainus. Russian Orthodoxy and Islam are the only religions with significant following among the population. Some of the villages are permanently manned by Russian soldiers (especially in Kunashir following recent tensions). Others are manned by civilians, which are mostly fishermen, workers of the fish factories, dockers, and social sphere workers (policemen, medics, teachers, etc.). Recent construction works on the islands attracts a lot of migrant workers from the rest of Russia and former USSR. As of 2014[update], there were only 8 inhabited islands out of a total of 56. Iturup Island is over 60% ethnically Ukrainian. On 8 February 2017 the Russian government gave names to five previously unnamed Kuril islands in Sakhalin Oblast: Derevyanko Island (after Kuzma Derevyanko, ), Gnechko Island (after Alexey Gnechko, ), Gromyko Island (after Andrei Gromyko, ), Farkhutdinov Island (after Igor Farkhutdinov, ) and Shchetinina Island (after Anna Shchetinina, ).
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.
The economic rise of the Russian Federation has been seen on the Kurils too. The most visible sign of improvement is the new construction in infrastructure. 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 Mount Baransky, an active volcano, where steam and hot water can be found.
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. In 2015 anti-aircraft missile systems 'Tor', 'BUK' missile systems, coastal defence missile systems 'Bastion', combat helicopters K-52 'Alligator' and 1 'Varshavyanka' project submarine came on defence of Kuril Islands.
The northernmost, Atlasov Island (Oyakoba in Japanese), is an almost perfect volcanic cone rising sheer out of the sea; it has been praised by the Japanese in haiku, wood-block prints, and other forms, in much the same way as the better-known Mt. Fuji.
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.
