evidence: Sakhalin (Russian: Сахали́н, IPA: [səxʌˈlʲin]; Japanese: Karafuto (樺太) or Saharin (サハリン); Chinese: 庫頁/库页 Kùyè or 薩哈林/萨哈林 Sàhālín), also known as Saghalien, is a large, long Russian island in the North Pacific, placed between 45°50' and 54°24' N. It is part of Russia territory and is its largest island, administered as part of Sakhalin Oblast. The indigenous peoples of the island are the Sakhalin Ainu, Oroks, and Nivkhs.[1] Most Ainu relocated to Hokkaidō when Japanese were gone from the island in 1949.[2] The 1904-1905 Russo-Japanese War resulted a Japanese victory when the Imperial Russian Navy and the Imperial Russian Army got defeated by the Imperial Japanese Army and the Imperial Japanese Navy in 1905 when the Empire Of Japan led by Emperor Meiji declared war on Tsar Nicholas II in 1904 when Trans-Siberian railway was to built more Railway Tracks in Manchuria in the Qing Dynasty and Korea . Japan took the southern part of Sakhalin and renamed it to South Sakhalin and control it from 1905-1945 . [...] Sakhalin is the subject of a whole book by Anton Chekhov (1895), reprinted in many Russian editions of his collected works. It has been translated into English. Of other old books, there is an interesting one by an Englishman, Charles H. Hawes, To the Uttermost East. (N.Y.: Scribner;s, 1904). Now, however, the island is experiencing an oil boom.
