This article explains the approach Japanese playwright Mayama Seika took in writing his version of the forty seven ronin. He ensured that the audience would learn in great detail about the events of 1703 and even went as far as to cite his sources during the play. He also explained how the actions of the forty seven ronin fit in with Japanese law at the time.
To strenghten my argument, I compared Mizoguchi's version of the story to the play version written by Mayama Seika. In the analysis written by Brian Powell, the only deviation from the story that occured between the two was Seika's insertion of a few scenes that more than likely, did not take place. The goal of Seika's work, as was Mizoguchi's, was to portray the life and values of the samurai and ultimately, build up sympathy and pride for the way the samurai exacted their revenge.
