Abstract Buddhism during the Heian period underwent significant transformations in the history of Japanese Buddhism. Under the influence of Emperor Kanmu’s religious policies, Buddhism in Japan experienced remarkable development. During this period, Japanese Buddhism was profoundly shaped by Chinese Buddhism in terms of sects, doctrines, and scriptures. Through their journeys to China, the monks Saichō and Kūkai founded two major Buddhist schools in Japan-Tendai and Shingon-which attracted a large number of followers across the country. Moreover, Heian-period Buddhism permeated deeply into the spiritual life and cultural consciousness of the Japanese people, influencing their lifestyles, customs, festivals, and moral conduct. Buddhism became a crucial component of Japan’s medieval cultural structure and functioned as a spiritual instrument of the ruling class. Its core values contributed to shaping the personality and character of the Japanese people, forming the spiritual foundation of the nation. The introduction of Buddhism from China enriched and diversified Japan’s spiritual life. The syncretism between Shinto and Buddhism further created distinctive features in the cultural and spiritual life of medieval Japan.
