This paper critically examines the concept and role of production dramaturg through Inner Grooming choreographed and directed by Kim Youngjin. In the 21st century, while awareness and acceptance of dramaturg are increasing in the domestic performing arts world, discussions on the concept and role of production dramaturg in dance creation remains underexplored and warrants further scholarly attention. The discussion draws on the characteristics of contemporary dance, the conceptual framework of the dramaturg, and an overview of Inner Grooming. To compensate for the scarcity of prior research, the study employs performance observation, program materials, dramaturg notes, and an interview with the dramaturg as primary sources. The analysis reveals that in the work Inner Grooming, Sako Kanako functioned as a production dramaturg throughout the entire production process, undertaking text analysis and research, script writing, assistant choreographer/director, and connection between the audience and the work.
