Mikael S. Adolphson is associate professor of Japanese cultural studies at the University of Alberta.

After graduating from high school in Kalmar the late 1970s, he graduated with a B.A. in History, Museum and Cultural Studies in 1985 from Lund University. A premodernist, he was inspired by the similarities between medieval Europe and Japan to focus his attention on pre-1600 Japan. He spent two years studying Japanese at Stockholm University before receiving a scholarship from the Japanese Education Ministry in 1986.

During the next two and a half years he lived in Kyoto and Osaka while studying at Kyoto University under the guidance of Professor Oyama Kyohei. During that time, he also coached volleyball at Osaka University of Foreign Studies and later at Kyoto University. Upon returning to Sweden, he became the head coach of the KFUM Göteborg women’s team, which took fifth place in the Elite League, in addition to winning several tournaments.

In 1989, he entered Stanford University's Ph.D. program with Professor Jeffrey Mass as his mentor. Returning to Kyoto University in the spring of 1992 for dissertation research, he also worked for the Japan Volleyball Association as an interpreter. He resumed at Stanford in the fall of 1993 and finished his dissertation two years later.

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.
