In Indigenizing Japan, archaeologist Joe E. Watkins provides a comprehensive look at the rich history and cultural resilience of the Ainu, the Indigenous people of Hokkaido, Japan, tracing their journey from ancient times to their contemporary struggles for recognition. Relaying the deep history of the islands of Japan, Watkins tells the archaeological story from the earliest arrivals some 40,000 years ago to 16,000 years ago when local cultures began utilizing pottery and stone tools. About 2,300 years ago, another group of people immigrated from the Korean peninsula into the Japanese archipelago, bringing wet rice agriculture with them. They intermarried with the people who were there, forming the basis of the contemporary Japanese majority culture. As the Japanese state developed on the central Islands of Honshu, Ryukyu, and Shikoku, the people of Hokkaido continued developing along a different trajectory with minimal interaction with the mainland until colonization in the mid-nineteenth century, when the people known as the Ainu came under Japanese governmental policy. Watkins’s insightful analysis highlights the Ainu’s enduring spirit and their resurgence as part of the global Indigenous movement. Key events such as the 1997 Nibutani Dam case and the 2007 recognition of the Ainu as Japan’s Indigenous people are explored in depth, showcasing the Ainu’s ongoing fight for cultural preservation and self-determination. By situating the Ainu’s experiences within broader global colonial histories, Indigenizing Japan underscores the shared struggles and resilience of Indigenous communities worldwide.
