This study will examine the integral role of owls in Ainu spiritual belief systems through the means of Ainu oral literature and Ainu material arts. In the past, the indigenous people known as Ainu lived only in northern Japan, including Kurile Islands (“Kurile Ainu”), Sakhalin (“Sakhalin Ainu”), and Hokkaido (“Hokkaido Ainu”). Today, Ainu people live across Japan; however, Hokkaido is considered their spiritual homeland and the majority of the population lives in this northern prefecture. This paper will focus on the group of people called “Hokkaido Ainu”. Before a large number of Japanese migrated to Hokkaido during the Meiji era (1868-1912), Ainu people had lived close to nature through various activities such as fishing, hunting, and gathering. As a result of these daily activities involving nature, the Ainu developed their spiritual belief systems. For example, they believe that various spirits exist in natural phenomena such as plants, insects, and animals. Among these animals, the bear, killer whale and owl are considered in many Ainu societies as the highest-ranked animal kamuy, meaning gods or deities. The Owl God in particular, is believed to be the guardian of the village. In this project, the symbolic representation of the Owl God in four different Ainu traditional folklores and various forms of arts will be carefully examined. The goal of this study is to demonstrate that although the language and physical communities are under threat by Japanese migration and a modern industrial economy, the spiritual belief in the Owl God as the guardian of the village continues to exist in contemporary Ainu works of art. In addition, I will argue that the representation of the Owl God, Kotan-kor-kamuy, is an important symbolic expression of Ainu cultural identity. / Graduate
