Uncertain Powers is an original and much-needed analysis of female leadership in medieval Japan. In challenging current scholarship by exploring the important political and economic roles of twelfth- and thirteenth-century Japanese royal women, Sachiko Kawai questions the traditional view of the era as one dominated by male retired monarchs and a warrior government. Instead the author populates it with royal wives and daughters who held the title of premier royal lady (nyoin) and owned extensive estates across the Japanese archipelago. Nyoin, whose power varied according to marital status, networks, and age, used their wealth and human networks to build temples and organize their entourages as salons to assert religious, cultural, and political influence. Confronted with social factors and gender disparities, they were motivated to develop coping strategies, the workings of which Kawai masterfully teases out from the abundant primary sources. Uncertain Powers presents a nuanced and groundbreaking study of the relationship between a nyoin's authority (her acknowledged rights) and her actual power (the ability to enforce those rights), demonstrating how, as members of political factions, as landlords, and as religious and cultural patrons, nyoin struggled to transform authority into power by means of cooperation, persuasion, compromise, and coercion.

Landed estates (shōen) produced much of the material wealth supporting all levels of late classical and medieval Japanese society. During the tenth through sixteenth centuries, estates served as sites of de facto government, trade network nodes, developing agricultural technology, and centers of religious practice and ritual. Although mostly farmland, many yielded nonagricultural products, including lumber, salt, fish, and silk, and provided livelihoods for craftsmen, seafarers, peddlers, and performers, as well as for cultivators. By the twelfth century, an estate "system" permeated much of the Japanese archipelago. This volume examines the system from three perspectives: the land itself; the power derived from and exerted over the land; and the religion institutions and individuals that were involved in landholding practices. Chapters by Japanese and Western scholars explore how the estate system arose, developed, and eventually collapsed. Several investigate a single estate or focus on agricultural techniques, while others survey estates in broad contexts such as economic change and maritime trade. Other chapters look at how we learn about estates by inspecting documents, landscape features, archaeological remains, and extant buildings and images; how representatives of every social stratum worked together to make the land productive and, conversely, how cooperative arrangements failed and rivals battled one another, making conflict as well as collaboration a hallmark of the system. On a more personal level, we follow the monk Chōgen's restoration of Ōbe Estate and his installation of a famous Amida triad in a temple he built on the premises; the strategies of royal ladies Jōsaimon - in, Hachijōin, and Kōkamon - in as they strove to keep their landholdings viable; and the murder of estate official Gorōzaemon, whose own neighbors killed him as a result of a much larger dispute between two powerful warrior families. Land, Power, and the Sacred represents a significant expansion and revision of our knowledge of medieval Japanese estates. A range of readers will welcome the primary source research and comparative perspectives it offers; those who do not specialize in Japanese medieval history but recognize the value of teaching the history of estates will find a chapter devoted to the topic invaluable.
