Chushingura (The Treasury of Loyal Retainers), also known as the story of the Forty-Six (or Forty-Seven) Ronin, is the most famous and perenially popular of all Japanese dramas. Written around 1748 as a puppet play, it is now better know in Kabuki performances. In the twentieth century, cinema and television versions have been equally successful. Donald Keene here presents a complete translation of the original text, with notes and an introduction that increase the reader's comprehension and enjoyment of the play. The introduction also elucidates the idea of loyalty. This traditional virtue, as exemplified in Chushingura, has never completely lost its hold on audiences, in spite of twentieth-century changes in Japanese society and moral ideas. Moreover, as Professor Keene points out, the excitement, color and violence expressed in the play may be considered the counterpoint to the austere restraint and understatement which are more commonly thought to be "traditionally" Japanese.
