Chushingura (The Treasury of Loyal Retainers), also known as the story of the Forty-Six (or Forty-Seven) Ronin, is the most famous and perennially popular of all Japanese dramas. Written around 1748 as a puppet play, it is now better known through Kabuki theater performances. Donald Keene's translation of the original text is presented here with a new preface and an introduction and notes to aid readers in their comprehension and enjoyment of the play.
