First published as a Monumenta Nipponica monograph in 1971, this impressive study chronicles the H�gen Incident of 1156, the abortive coup d'�tat that marked the emergence of the military class as a political power in Japan. After being unavailable for years, this photo-reprint of the original edition contains not only the complete English translation of the work, but also virtually all that is needed for fully understanding it: footnotes, essays on the subject matter, appendices with references to other chronicles and histories, and a table of episodes from the various texts.
