Monsters, Animals, and Other Worlds is a collection of twenty-five medieval Japanese tales of border crossings and the fantastic, featuring demons, samurai, talking animals, amorous plants, and journeys to supernatural realms. The most comprehensive compendium of short medieval Japanese fiction in English, Monsters, Animals, and Other Worlds illuminates a rich world of literary, Buddhist, and visual culture largely unknown today outside of Japan.These stories, called otogizoshi, or Muromachi tales (named after the Muromachi period, 1337 to 1573), date from approximately the fourteenth through seventeenth centuries. Often richly illustrated in a painted-scroll format, these vernacular stories frequently express Buddhist beliefs and provide the practical knowledge and moral education required to navigate medieval Japanese society. The otogizoshi represent a major turning point in the history of Japanese literature. They bring together many earlier types of narrative court tales, military accounts, anecdotes, and stories about the divine origins of shrines and temples joining book genres with parlor arts and the culture of itinerant storytellers and performers. The works presented here are organized into three thematically overlapping sections titled, Monsters, Warriors, and Journeys to Other Worlds, Buddhist Tales, and Interspecies Affairs. Each translation is prefaced by a short introduction, and the book features images from the original scroll paintings, illustrated manuscripts, and printed books.
