In this paper, first I clarify the formation of the theory of theatrical reform and the state of construction of improved theaters that were based on reforms in theatrical performance. Then I consider the influences on architecture of the reform of theatrical performance. Through the question of the Imperial Theater performance (a reaction to the 1911 request for a Noh performance at the Imperial Theater), which was a debate in the world of Noh, I examine, through the opinions and dissatisfactions of relevant figures regarding Noh theaters, the influence of the reform theaters on Noh theaters.
