Towering over the Kanto Plain, the sacred mountain oyama (literally, "Big Mountain") has loomed large over the religious landscape of early modern Japan.

By the Edo period (1600-1868), the revered peak had undergone a transformation from secluded spiritual retreat to popular pilgrimage destination. Its status as a regional landmark among its devotees was boosted by its proximity to the shogunal capital and the wide appeal of its amalgamation of Buddhism, Shinto, mountain asceticism, and folk beliefs. The influence of the oyama cult--the intersecting beliefs, practices, and infrastructure associated with the sacred site--was not lost on the ruling Tokugawa shogunate, which saw in the pilgrimage an opportunity to reinforce the communal ideals and social structures that the authorities espoused.

Barbara Ambros provides a detailed narrative history of the mountain and its place in contemporary society and popular religion by focusing on the development of the oyama cult and its religious, political, and socioeconomic contexts. Richly illustrated and carefully researched, this study emphasizes the importance of "site" or "region" in considering the multifaceted nature and complex history of religious practice in Tokugawa Japan.

The Sea and the Sacred in Japan is the first book to focus on the role of the sea in Japanese religions. While many leading Shinto deities tend to be understood today as unrelated to the sea, and mountains are considered the privileged sites of sacredness, this book provides new ways to understand Japanese religious culture and history. Scholars from North America, Japan and Europe explore the sea and the sacred in relation to history, culture, politics, geography, worldviews and cosmology, space and borders, and ritual practices and doctrines. Examples include Japanese indigenous conceptualizations of the sea from the Middle Ages to the 20th century; ancient sea myths and rituals; sea deities and sea cults; the role of the sea in Buddhist cosmology; and the international dimension of Japanese Buddhism and its maritime imaginary.
