Noh and kyōgen plays written after the Meiji era are known as shinsaku, or “new works” (shinsaku-noh, shinsaku-kyōgen) to differentiate them from the classical works (genkō-kyoku). Some shinsaku rework classical productions, while some take up current issues. Some have gained such popularity that they have been performed repeatedly. The creation of shinsaku plays calls for a sort of energy traditional arts seem to lose, an energy which gives the performers and the audience a new perspective and emotional response, providing a valuable opportunity to reconsider the classics. Plays that haven’t been performed for a long time and are revived to be performed again are known as fuk'kyoku, or “revived plays.”
