Khabarovsk Krai in the context of "Krai"

Sakhalin (Russian: Сахалин, IPA: [səxɐˈlʲin]) 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 island's name is derived from the Manchu word Sahaliyan (ᠰᠠᡥᠠᠯᡳᠶᠠᠨ), which was the name of the Qing dynasty city of Aigun. The Ainu people of Sakhalin paid tribute to the Yuan, Ming, and Qing dynasties and accepted official appointments from them. Sometimes the relationship was forced but control from dynasties in China was loose for the most part.

Okhotsk (Russian: Охотск, IPA: [ɐˈxotsk]) is an urban locality (a work settlement) and the administrative center of Okhotsky District of Khabarovsk Krai, Russia, located at the mouth of the Okhota River on the Sea of Okhotsk. Population: 4,215 (2010 census); 5,738 (2002 census); 9,298 (1989 Soviet census).

The Okhota (Russian: Охота) is a river in Okhotsky District, Khabarovsk Krai, which flows south to the Sea of Okhotsk. It is 393 kilometres (244 mi) long, and its drainage basin covers 19,100 square kilometres (7,400 sq mi).

Manchuria is a historical region in northeast Asia encompassing the entirety of present-day northeast China and parts of the modern-day Russian Far East south of the Uda River and the Tukuringra-Dzhagdy Ranges. The exact geographical extent varies depending on the definition: in the narrow sense, the area constituted by three Chinese provinces of Heilongjiang, Jilin, and Liaoning as well as the eastern Inner Mongolian prefectures of Hulunbuir, Hinggan, Tongliao, and Chifeng; in a broader sense, historical Manchuria includes those regions plus the Amur river basin, parts of which were ceded to the Russian Empire by the Manchu-led Qing dynasty during the Amur Annexation of 1858–1860. The parts of Manchuria ceded to Russia are collectively known as Outer Manchuria or Russian Manchuria, which include present-day Amur Oblast, Primorsky Krai, the Jewish Autonomous Oblast, the southern part of Khabarovsk Krai, and the eastern edge of Zabaykalsky Krai.

The name Manchuria is an exonym (derived from the endonym "Manchu") of Japanese origin. The history of "Manchuria" (Manzhou) as a toponym in China is disputed, with some scholars believing it was never used while others believe it was by the late 19th century. The area was historically referred to by various names in the Qing dynasty such as Guandong (East of the Pass) or the Three Provinces referring to Fengtian (Liaoning), Heilongjiang, and Jilin. Manchuria as a geographical term was first used in the 18th or 19th centuries by the Japanese before spreading to Europe. The term was promoted by the Empire of Japan in support for the existence of its puppet state, Manchukuo. Although the toponym is still used, some scholars treat the term with caution or avoid it altogether due to its association with Japanese colonialism. The term is deprecated in China due to its association with Japanese imperialism and ethnic connotations. As a result, areas once considered part of Manchuria are simply referred to as the Northeast. The Three Provinces and the Northeast were also in concurrent use among the Japanese along with Manchuria until the Mukden incident of 1931.

Sakhalin Oblast (Russian: Сахали́нская о́бласть, romanized: Sakhalinskaya oblastʹ, IPA: [səxɐˈlʲinskəjə ˈobləsʲtʲ]) is a federal subject of Russia (an oblast) 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.

The vast majority of the oblast's residents are ethnic Russians, with a small minority of Sakhalin Koreans. Sakhalin Oblast is rich in natural gas and oil, and is Russia's second wealthiest federal subject after the Tyumen Oblast. It borders by sea Khabarovsk Krai to the west and Kamchatka Krai to the north, along with Hokkaido, Japan to the south.

The Ainu in Russia are an Indigenous people of Siberia located in Sakhalin Oblast, Khabarovsk Krai and Kamchatka Krai. The Russian Ainu people (Aine; Russian: айны, romanized: Ayny), also called Kurile (курилы, kurily), Kamchatka's Kurile (камчатские курилы, kamchatskiye kurily / камчадальские айны, kamchadalskiye ayny) or Eine (эйны, eyny), can be subdivided into six groups.

Although only around 100 people currently identify themselves as Ainu in Russia (according to the census of 2010), it is believed that at least 1,000 people are of significant Ainu ancestry. The low numbers identifying as Ainu are a result of the refusal by the government of the Russian Federation to recognise the Ainu as a "living" ethnic group. Most of the people who identify themselves as Ainu live in Kamchatka Krai, although the largest number of people who are of Ainu ancestry (without acknowledging it) are found in Sakhalin Oblast. Many local people are ethnically Ainu or have significant Ainu ancestry but identify as Russian or Nivkh and speak Russian as mother tongue, often not knowing of their Ainu ancestry.

Khabarovsk (Russian: Хабаровск [xɐˈbarəfsk] ) is the largest city and the administrative centre of Khabarovsk Krai, Russia, located 30 kilometers (19 mi) from the China–Russia border, at the confluence of the Amur and Ussuri Rivers, about 800 kilometers (500 mi) north of Vladivostok. As of the 2021 Russian census, it had a population of 617,441. It was known as Khabarovka until 1893.

The city was the administrative center of the Far Eastern Federal District of Russia from 2002 until December 2018, when the status was given to Vladivostok. As is typical of the interior of the Russian Far East, Khabarovsk has an extreme climate with strong seasonal swings resulting in strong, cold winters and relatively hot and humid summers.
