Soka Gakkai is Japan's largest and most influential new religious organization: It claims more than 8 million Japanese households and close to 2 million members in 192 countries and territories. The religion is best known for its affiliated political party, Komeito (the Clean Government Party), which comprises part of the ruling coalition in Japan's National Diet, and it exerts considerable influence in education, media, finance, and other key areas.Levi McLaughlin's comprehensive account of Soka Gakkai draws on nearly two decades of archival research and non-member fieldwork to account for its institutional development beyond Buddhism and suggest how we should understand the activities and dispositions of its adherents. McLaughlin explores the group's Nichiren Buddhist origins and turns to insights from religion, political science, anthropology, and cultural studies to characterize Soka Gakkai as mimetic of the nation-state. Ethnographic vignettes combine with historical evidence to demonstrate ways Soka Gakkai's twin Buddhist and modern humanist legacies inform the organization's mimesis of the modern Japan in which the group took shape. To make this argument, McLaughlin analyzes Gakkai sources heretofore untreated in English-language scholarship; provides a close reading of the serial novel The Human Revolution, which serves the Gakkai as both history and de facto scripture; identifies ways episodes from members' lives form new chapters in its growing canon; and contributes to discussions of religion and gender as he chronicles the lives of members who simultaneously reaffirm generational transmission of Gakkai devotion as they pose challenges for the organization's future. Readers looking for analyses of the nation-state and strategies for understanding New Religions and modern Buddhism will find Soka Gakkai's Human Revolution to be an especially thought-provoking study that offers widely applicable theoretical models.
