From the early seventeenth to the mid-nineteenth century Japan saw the creation, development, and apparent disappearance of the field of natural history, or "honzogaku." Federico Marcon traces the changing views of the natural environment that accompanied its development by surveying the ideas and practices deployed by "honzogaku" practitioners and by vividly reconstructing the social forces that affected them. These include a burgeoning publishing industry, increased circulation of ideas and books, the spread of literacy, processes of institutionalization in schools and academies, systems of patronage, and networks of cultural circles, all of which helped to shape the study of nature. In this pioneering social history of knowledge in Japan, Marcon shows how scholars developed a sophisticated discipline that was analogous to European natural history but formed independently. He also argues that when contacts with Western scholars, traders, and diplomats intensified in the nineteenth century, the previously dominant paradigm of "honzogaku "slowly succumbed to modern Western natural science not by suppression and substitution, as was previously thought, but by creative adaptation and transformation.

Japan’s monastic warriors have fared poorly in comparison to the samurai, both in terms of historical reputation and representations in popular culture. Often maligned and criticized for their involvement in politics and other secular matters, they have been seen as figures separate from the larger military class. However, as Mikael Adolphson reveals in his comprehensive and authoritative examination of the social origins of the monastic forces, political conditions, and warfare practices of the Heian (794–1185) and Kamakura (1185–1333) eras, these "monk-warriors"(sôhei) were in reality inseparable from the warrior class. Their negative image, Adolphson argues, is a construct that grew out of artistic sources critical of the established temples from the fourteenth century on. In deconstructing the sôhei image and looking for clues as to the characteristics, role, and meaning of the monastic forces, The Teeth and Claws of the Buddha highlights the importance of historical circumstances; it also points to the fallacies of allowing later, especially modern, notions of religion to exert undue influence on interpretations of the past. It further suggests that, rather than constituting a separate category of violence, religious violence needs to be understood in its political, social, military, and ideological contexts.
