Ainu peopleThe Ainu are an indigenous people of the lands surrounding the Sea of Okhotsk, including Hokkaido Island, Northeast Honshu Island, Sakhalin Island, the Kuril Islands, the Kamchatka Peninsula, and Khabarovsk Krai, since before the arrival of the Yamato Japanese and Russians. These regions are referred to as Ezo in historical Japanese texts. Official estimates place the total Ainu population of Japan at 25,000.
History of JapanThe first human inhabitants of the Japanese archipelago have been traced to the Paleolithic, around 38-40,000 years ago. The Jōmon period, named after its cord-marked pottery, was followed by the Yayoi period in the first millennium BC when new inventions were introduced from Asia. During this period, the first known written reference to Japan was recorded in the Chinese Book of Han in the first century AD. Around the 3rd century BC, the Yayoi people from the continent immigrated to the Japanese archipelago and introduced iron technology and agricultural civilization.
Cold WarThe Cold War was a period of geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc. The term cold war is used because there was no large-scale fighting directly between the two superpowers, but they each supported opposing sides in major regional conflicts known as proxy wars. The conflict was based on the ideological and geopolitical struggle for global influence by these two superpowers, following their roles as the Allies of World War II that led to victory against Nazi Germany and Imperial Japan in 1945.
Wakkanaiis a city located in Sōya Subprefecture, Hokkaido, Japan. It is the capital of Sōya Subprefecture. It contains Japan's northernmost point, Cape Sōya, from which the Russian island of Sakhalin can be seen.

Sea of JapanThe Sea of Japan is the marginal sea between the Japanese archipelago, Sakhalin, the Korean Peninsula, and the mainland of the Russian Far East. The Japanese archipelago separates the sea from the Pacific Ocean. Like the Mediterranean Sea, it has almost no tides due to its nearly complete enclosure from the Pacific Ocean. This isolation also affects faunal diversity and salinity, both of which are lower than in the open ocean. The sea has no large islands, bays or capes.
Kamchatka PeninsulaThe Kamchatka Peninsula (Poluostrov Kamchatka, pəlʊˈostrəf kɐmˈt͡ɕætkə) is a peninsula in the Russian Far East, with an area of about . The Pacific Ocean and the Sea of Okhotsk make up the peninsula's eastern and western coastlines, respectively. Immediately offshore along the Pacific coast of the peninsula runs the Kuril–Kamchatka Trench. The Kamchatka Peninsula, the Commander Islands, and the Karaginsky Island, constitute the Kamchatka Krai of the Russian Federation.
KunashirKunashir Island (Kunashír; Kunashiri-tō; クナシㇼ), possibly meaning Black Island or Grass Island in Ainu, is the southernmost island of the Kuril Islands archipelago. The island has been under Russian administration since the end of World War II, when Soviet forces took possession of the Kurils. It is claimed by Japan (see Kuril Islands dispute). Kunashir lies between the straits of Kunashir Island, Catherine, Izmena, and South Kuril. Kunashir Island is visible from the nearby Japanese island of Hokkaido, from which it is separated by the Nemuro Strait.
