The "I Ching" in the Shinto Thought of Tokugawa Japan

The "I Ching" had an important influence on Tokugawa Shinto. First, it played a crucial role in the discussion of Confucian-Shinto relations; many Tokugawa Confucians and Shintoists used it to uphold the doctrine of the unity of Confucianism and Shinto, and Shintoists and scholars of National Learning (kokugaku) used it for its metaphysical and divinational value. Second, scholars of National Learning transformed it from a Confucian classic into a Shinto text, claiming that it was the handiwork of a Japanese deity.
