Gunsanjwa is a theater established in Gunsan during the Japanese colonial period, and was a representative local theater that grew up with the floating population and commercial capital of Gunsan. Since Gunsanjwa was a theater located in an area separate from the Gyeongbu Line railway, there were many disadvantages in supplying and distributing theater/movie/performance content. However, Gunsanjwa was a theater where it was possible to perform tours to Honam(Jeollado), and it also had a relative advantage that it could be occupied exclusively if it aimed for the route(the western part of Korea). As a result, Gunsanjwa was able to operate as a theater that attracted attention from the early days. In order to study Gunsanjwa, it is necessary to understand not only the aspect of the theater, but also the geographical situation, the size of the city, and the transportation network(railway network) at the time. In order to examine the reality and characteristics of Gunsanjwa, this study aimed to synthesize data on maps, newspaper articles, performance photos, and related persons at the time. In addition, this study attempted to analyze the location, scale, facilities, managers, and performance contents of Gunsanjwa based on this.
