Abstract
Neo-Confucian influence in early modern Japan was highly intellectual, indicating that Confucian ideals did not change the nature of Japanese norms of social lives. For early modern Japanese intellectuals, the conflict and contradiction between reality and ideals had always been a source of debate and inspiration. Within the theme of Neo-Confucian rites, the contradiction was highlighted owing to the fact that it included a guideline for authentic ancestral worship and religious policy. Once introduced within the Japanese circumstances of the day, Confucian understanding on spirits and proper rites lead Japanese scholars to define what was legitimate worship in the format of state religion: it was necessary to authorize traditional Japanese worship toward domestic shrines. Within thepractical process of policy making, it must be noted that a keen interest toward local beliefs had emerged through the discussion. Arai Hakuseki (1657‐1725) reflects such political interest within his work ‘Kishinron’. In order to understand the impact of Japanese interpretation of Neo-Confucian ideals, it is essential to focus on the interrelationship between religious policy and interest toward local beliefs.
