Ainu language in the context of "Cape Tappi"

Hokkaido (Japanese: 北海道, Hepburn: Hokkaidō; pronounced [hok.kaꜜi.doː] , lit. 'Northern Sea Circuit'; Ainu: Aynu Mosir, lit. 'Land of the Ainu') is the second-largest and northernmost of Japan's four main islands. Together with its surrounding islands, it comprises the largest and northernmost prefecture, making up its own region. The Tsugaru Strait separates Hokkaidō from Honshu. The two islands are connected by railway via the Seikan Tunnel.

The largest city on Hokkaido is its capital, Sapporo, which is also its only ordinance-designated city. Sakhalin lies about 43 kilometres (27 mi) to the north of Hokkaidō. To the east and northeast are the Kuril Islands, which are administered by Russia. The four most southerly are claimed by Japan. Hokkaido's position on the northern end of the Japanese archipelago results in a colder climate, with the island seeing significant snowfall each winter. Despite the harsher climate, it serves as an agricultural breadbasket for many crops.

A language isolate, or an isolated language, is a language that has no demonstrable genetic relationship with any other languages. Basque in Europe, Ainu and Burushaski in Asia, Sandawe in Africa, Haida and Zuni in North America, Kanoê and Trumai in South America, and Tiwi in Oceania are all examples of such languages. The exact number of language isolates is yet unknown due to insufficient data on several languages.

One explanation for the existence of language isolates is that they might be the last remaining member of a larger language family. Such languages might have had relatives in the past that have since disappeared without being documented, leaving them an orphaned language. One example is the Ket language spoken in central Siberia, which belongs to the wider Yeniseian language family; had it been discovered in recent times independently from its now extinct relatives, such as Yugh and Kott, it would have been classified as an isolate. Another explanation for language isolates is that they arose independently in isolation and thus do not share a common linguistic genesis with any other language but themselves. This explanation mostly applies to sign languages that have developed independently of other spoken or signed languages.

Kana (仮名; Japanese pronunciation: [ka.na]) are syllabaries used to write Japanese phonological units, morae. In current usage, kana most commonly refers to hiragana and katakana. It can also refer to their ancestor magana (真仮名; lit. 'true kana'), which were Chinese characters used phonetically to transcribe Japanese (e.g. man'yōgana); and hentaigana, which are historical variants of the now-standard hiragana.

Katakana, with a few additions, are also used to write Ainu. A number of systems exist to write the Ryūkyūan languages, in particular Okinawan, in hiragana. Taiwanese kana were used in Taiwanese Hokkien as ruby text for Chinese characters in Taiwan when it was under Japanese rule.

Hokkaido (Japanese: 北海道, Hepburn: Hokkaidō; pronounced [hok.kaꜜi.doː] , lit. 'Northern Sea Circuit'; Ainu: Aynu Mosir, lit. 'Land of the Ainu') is the second-largest and northernmost of Japan's four main islands.

Kunashir Island (Russian: Кунаши́р, romanized: Kunashír; Japanese: 国後島, romanized: Kunashiri-tō; Ainu: クナシㇼ, romanized: Kunasir), possibly meaning Black Island or Grass Island in Ainu, is the southernmost island of the Kuril Islands. 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).

Urup (Japanese: 得撫島, romanized: Uruppu-tō; Russian: Уру́п, romanized: Urúp, Ainu: ウルㇷ゚, romanized: Urup) is an uninhabited volcanic island in the Kuril Islands chain in the south of the Sea of Okhotsk, northwest Pacific Ocean. Its name is derived from the Ainu language word urup, meaning "sockeye salmon".

The Ainu are an indigenous ethnic group who reside in northern Japan and southeastern Russia, including Hokkaido and the Tōhoku region of Honshu, as well as the land surrounding the Sea of Okhotsk, such as Sakhalin, the Kuril Islands, the Kamchatka Peninsula, and the Khabarovsk Krai. They have occupied these areas, known to them as "Ainu Mosir" (Ainu: アイヌモシㇼ, lit. 'the land of the Ainu'), since before the arrival of the modern Yamato and Russians. These regions are often referred to as Ezochi (蝦夷地) and its inhabitants as Emishi (蝦夷) in historical Japanese texts. Along with the Yamato and Ryukyuan ethnic groups, the Ainu people are one of the primary historic ethnic groups of Japan and are along with the Ryukyuans and Bonin Islanders one of the few ethnic minorities native to the Japanese archipelago.

Official surveys of the known Ainu population in Hokkaido received 11,450 responses in 2023, and the Ainu population in Russia was estimated at 300 in 2021. Unofficial estimates in 2002 placed the total population in Japan at 200,000 or higher, as the near-total assimilation of the Ainu into Japanese society has resulted in many individuals of Ainu descent having no knowledge of their ancestry.
