Final answer:
The Ainu people were not the last to settle in feudal Japan.
Step-by-step explanation:
Ainu, indigenous people of Hokkaido, Sakhalin, and the Kuril Islands who were culturally and physically distinct from their Japanese neighbours until the second part of the 20th century. The Ainu may be descendants of an indigenous population once widely spread over northern Asia; many contemporary Ainu claim some connection to Japan’s prehistoric Jōmon culture. The traditional Ainu language, an isolate with a number of dialects, had been almost completely supplanted by Japanese by the early 21st century; a language-revitalization movement initiated formal instruction in Ainu in the 1980s.
The Ainu people were not the last to settle in feudal Japan. The Ainu are indigenous people who inhabited Hokkaido, the northernmost island of Japan. Their presence in Japan dates back to prehistoric times, long before the establishment of feudal Japan during the medieval period.
