This paper introduces the generation of explanations for a stage-performing structural simulation system using the animation of kabuki dance that we have developed. After considering the explanation function in the context of narratives and kabuki knowledge, we present a mechanism in the aforementioned system that automatically determines the content and method of an explanation according to the degree of the user’s interest and knowledge. Through this trial, we consider effective explanation methods for narrative generation and, in this study, the use of kabuki-related knowledge.
