the most eminent scholar in Shintō and Japanese classics. His father, a textile merchant, died when Norinaga was 11 years old, but with his mother's encouragement he studied medicine in Kyōto and became a physician. In time he came under the influence of the National Learning (Kokugaku) movement, which emphasized the importance of Japan's own literature. Motoori applied careful philological methods to the study of the Koji-ki (Kojiki), The Tale of Genji, and other classical literature and stressed mono no aware (“sensitiveness to beauty”) as the central concept of Japanese literature.

Motoori's study of Japanese classics, especially the Koji-ki, provided the theoretical foundation of the modern Shintō revival. Rejecting Buddhist and Confucian influence on the interpretation of Shintō, he instead traced the genuine spirit of Shintō to ancient Japanese myths and the sacred traditions transmitted from antiquity. Motoori also reaffirmed the ancient Japanese concept of musubi (the mysterious power of all creation and growth), which has become one of the main tenets of modern Shintō. While he accepted ethical dualism, he believed that evil existed for the sake of good, as an antithetic element of the dialectical higher good.

Motoori's 49-volume commentary on the Koji-ki (Koji-ki-den), completed in 1798 after 35 years of effort, is incorporated in the Moto-ori Norinaga Zenshū, 12 vol. (1926–27; “Complete Works of Motoori Norinaga”).
