Sakhalin is an island in Northeast Asia. Its north coast lies 6.5 km (4.0 mi) off the southeastern coast of Khabarovsk Krai in Russia, while its southern tip lies 40 kilometres (25 mi) north of the Japanese island of Hokkaido. An island of the West Pacific, Sakhalin divides the Sea of Okhotsk to its east from the Sea of Japan to its southwest. It is administered as part of Sakhalin Oblast and is the largest island of Russia, with an area of 72,492 square kilometres (27,989 sq mi). The island has a population of roughly 500,000, the majority of whom are Russians. The indigenous peoples of the island are the Ainu, Oroks, and Nivkhs, who are now present in very small numbers.
The Russian Far East is a region in North Asia. It is the easternmost part of Russia and the Asian continent, and is coextensive with the Far Eastern Federal District, which encompasses the area between Lake Baikal and the Pacific Ocean. The area's largest city is Khabarovsk, followed by Vladivostok. The region shares land borders with the countries of Mongolia, China, and North Korea to its south, as well as maritime boundaries with Japan to its southeast, and with the United States along the Bering Strait to its northeast.
The Japanese diaspora and its individual members, known as Nikkei or as Nikkeijin, comprise the Japanese emigrants from Japan residing in a country outside Japan. Emigration from Japan was recorded as early as the 15th century to the Philippines, but did not become a mass phenomenon until the Meiji period (1868–1912), when Japanese emigrated to the Philippines and to the Americas. There was significant emigration to the territories of the Empire of Japan during the period of Japanese colonial expansion (1875–1945); however, most of these emigrants repatriated to Japan after the 1945 surrender of Japan ended World War II in Asia.
The Kuril Islands dispute, known as the Northern Territories dispute in Japan, is a territorial dispute between Japan and Russia over the ownership of the four southernmost Kuril Islands. The Kuril Islands are a chain of islands that stretch between the Japanese island of Hokkaido at their southern end and the Russian Kamchatka Peninsula at their northern end. The islands separate the Sea of Okhotsk from the Pacific Ocean. The four disputed islands, like other islands in the Kuril chain which are not in dispute, were unilaterally annexed by the Soviet Union following the Kuril Islands landing operation at the end of World War II. The disputed islands are under Russian administration as the South Kuril District and part of the Kuril District of the Sakhalin Oblast. They are claimed by Japan, which refers to them as its Northern Territories or Southern Chishima, and considers them part of the Nemuro Subprefecture of Hokkaido Prefecture.
Sakhalin Oblast is a federal subject of Russia comprising the island of Sakhalin and the Kuril Islands in the Russian Far East. The oblast has an area of 87,100 square kilometers (33,600 sq mi). Its administrative center and largest city is Yuzhno-Sakhalinsk. As of the 2021 Census, the oblast has a population of 466,609.
Yuzhno-Sakhalinsk is a city and the administrative center of Sakhalin Oblast, Russia. It is located on Sakhalin Island in the Russian Far East, north of Japan. Gas and oil extraction as well as processing are amongst the main industries on the island. It was called Vladimirovka (Влади́мировка) from 1882 to 1905, then Toyohara during its period of Imperial Japanese control from 1905 to 1946. As of the 2010 Census, its population was 181,728.
Karafuto Agency, from 1943 Karafuto Prefecture, commonly known as South Sakhalin, was a part of the Empire of Japan on Sakhalin. It was part of the gaichi from 1907 to 1943 and later a prefecture as part of the naichi until 1945.
Relations between the Soviet Unionand Japan between the Communist takeover in 1917 and the collapse of Communism in 1991 tended to be hostile. Japan had sent troops to counter the Bolshevik presence in Russia's Far East during the Russian Civil War, and both countries had been in opposite camps during World War II and the Cold War. In addition, territorial conflicts over the Kuril Islands and South Sakhalin were a constant source of tension. These, with a number of smaller conflicts, prevented both countries from signing a peace treaty after World War II, and even today matters remain unresolved.
Relations between the Russian Federation and Japan are the continuation of the relationship of Japan with the Soviet Union from 1917 to 1991, and with the Russian Empire from 1855 to 1917. Historically, the two countries had cordial relations until a clash of territorial ambitions in the Manchuria region of northeastern China led to the Russo–Japanese War in 1904, ending in a Japanese victory which contributed to the weakening of the monarchy in Russia. Japan would later intervene in the Russian Civil War from 1918 until 1922, sending troops to the Russian Far East and Siberia. That was followed by border conflicts between the new Soviet Union and the Empire of Japan throughout the 1930s. The two countries signed a nonaggression pact in 1941, although the Soviet government declared war on Japan anyway in August 1945, invading the Japanese puppet state of Manchukuo as well as seizing the Kuril chain of islands just north of Japan. The two countries ended their formal state of war with the Soviet–Japanese Joint Declaration of 1956, but as of 2022 have not resolved this territorial dispute over ownership of the Kurils. Due to the 2022 Russian invasion of Ukraine, relations became very tense after Japan imposed sanctions against Russia. Russia placed Japan on a list of "unfriendly countries", along with South Korea, European Union members, NATO members, Australia, New Zealand, Switzerland, Singapore, Taiwan, and Ukraine.
The Soviet–Japanese War was a campaign of the Second World War that began with the Soviet invasion of Manchuria following the Soviet declaration of war against Japan on 8 August 1945. The Soviet Union and Mongolian People's Republic toppled the Japanese puppet states of Manchukuo in Manchuria and Mengjiang in Inner Mongolia, as well as northern Korea, Karafuto on the island of Sakhalin, and the Kuril Islands. The defeat of Japan's Kwantung Army helped bring about the Japanese surrender and the end of World War II. The Soviet entry into the war was a significant factor in the Japanese government's decision to surrender unconditionally, as it was made apparent that the Soviet Union was not willing to act as a third party in negotiating an end to hostilities on conditional terms.
Sakhalin Koreans are Russian citizens and residents of Korean descent living on Sakhalin Island, who can trace their roots to the immigrants from the Gyeongsang and Jeolla provinces of Korea during the late 1930s and early 1940s, the latter half of the Japanese ruling era.
Japanese language education in Russia formally dates back to December 1701 or January 1702, when Dembei, a shipwrecked Japanese merchant, was taken to Moscow and ordered to begin teaching the language as soon as possible. A 2006 survey by the Japan Foundation found 451 teachers teaching the language to 9,644 students at 143 institutions; the number of students had grown by 4.8% since the previous year. Aside from one Japanese-medium school serving Japanese people in Russia, virtually all Japanese language education in Russia throughout history has been aimed at non-native speakers. As of 2021, according to the Japan Foundation, 12,426 people were learning Japanese in Russia.
Russia–South Korea relations or Russian–South Korean relations are the bilateral foreign relations between Russia and South Korea. Modern relations between the two countries began on September 30, 1990. Due to the 2022 Russian invasion of Ukraine, relations became very tense after South Korea imposed sanctions against Russia. Russia placed South Korea on a list of "unfriendly countries", along with Taiwan, Japan, Singapore, the United States, European Union members, NATO members, Australia, New Zealand, Switzerland, Micronesia and Ukraine.
Ethnic Chinese in Russia officially numbered 39,483 according to the 2002 census. However, this figure is contested, with the Overseas Community Affairs Council of Taiwan claiming 998,000 in 2004 and 2005, and Russian demographers generally accepting estimates in the 200,000–400,000 range as of 2004. Temporary migration and shuttle trade conducted by Chinese merchants are most prevalent in Russia's Far Eastern Federal District, but most go back and forth across the border without settling down in Russia; the Chinese community in Moscow has a higher proportion of long-term residents. Their number in Russia has been shrinking since 2013.
North Koreans in Russia consist mainly of three groups: international students, guest workers, and defectors and refugees. A 2006 study by Kyung Hee University estimated their total population at roughly 10,000.
After World War II there were from 560,000 to 760,000 Japanese personnel in the Soviet Union and Mongolia interned to work in labor camps as POWs. Of them, it is estimated that between 60,000 and 347,000 died in captivity.
The evacuation of Karafuto (Sakhalin) and the Chishima (Kuril) islands refers to the events that took place during the Pacific theater of World War II as the Japanese population left these areas, to August 1945 in the northwest of the main islands of Japan.
The Japan–Russia border is the de facto maritime boundary that separates the territorial waters of the two countries. According to the Russia border agency, the border's length is 194.3 km (120.7 mi).
The Soviet invasion of South Sakhalin, also known as the Battle of Sakhalin, was the Soviet invasion of the Japanese portion of Sakhalin Island known as Karafuto Prefecture. The invasion was part of the Soviet–Japanese War, a minor campaign in the Asian Theatre during Second World War.
The Sakhalin Regional Museum is a museum in Yuzhno-Sakhalinsk on the Russian island of Sakhalin. It is the largest museum in the Sakhalin Oblast. The Museum collects, researches, and displays materials relating to the natural history, archaeology, history, and ethnography of the region.
