This study introduces the jishū nuns who participated alongside monks as fellow practitioners—not as wives, daughters, or mothers. They were partners in a Pure Land religious school devoted to encompassing the world with the name Amida Buddha through their continuous chanting of the nembutsu. The popularity of the jishū rose in Japan during the late thirteenth century and continues to operate today, now as the Ji-sect. This book focuses on the activities of the nuns from the fourteenth and fifteenth centuries, before the various jishū groups were united into a single sect. During this time, female members were entrusted to run local practice halls which were mixed gender. They offered memorial services and other rituals to local lay believers and participated in itinerant missions, traveling across the provinces reaching out to as many people as possible. The prominent roles and history of these nuns and jishū’s mixed-gender past have been largely forgotten. This book is a step forward in bringing back the lost voices of the women, demonstrating how they held decisive roles in the formation, spread, and popularity of this religious movement.
