'Backstage tours' are gaining popularity at domestic performance venues recently. Major performance venues such as the Sejong Culture Center and the Sungnam Art Center provide audiences with opportunities to deepen their understanding of performances through various contents, including backstage tours, rehearsal room openings, and demonstrations of lighting and sound equipment. Although some tours are operated for a fee, they are sold out every day, showing high demand. This is analyzed as being due to the maturity of domestic performance art culture and the increase in fans who want to understand works from multiple angles. Backstage tours allow audiences to experience the hidden stories of performances, contributing to increased satisfaction with the work.
