Gunsan is a port city on the west coast of Korea. The Foreign Settlement at Gunsan was formed in 1899, and Gunsan city government was founded in 1914. This paper aims to clarify the Gunsan urban planning in 1938, which was implemented under the Chosen urban planning ordinance.
 This study focuses on two points, one is consensus-building of Gunsan urban planning (1938) and the other is the analysis of its characteristics.
 Previous studies of Korean cities in the former Japanese colonial period were concentrated in large cities such as Seoul, Busan and Incheon. Therefore, significance of this study is that focused on the local city which has insufficient study.
 This study concludes followings;
 1) The Gunsan urban planning (1938) was set as the urban planning area about six times the size of the administrative district at that time. In comparison with this, other cities were designated planning area that are about two to three times as large as administrative district. This characteristic was intended to secure a vast industrial area, not an urban plan due to the population growth rate of Gunsan. In addition, this was planned by the Gunsan City Government before the Chosen Government-general starting to make a planning of Gunsan.
 2) The Gunsan urban planning (1938) was planned a street network in which a circular square was placed at the intersection of a wide street by the Chosen Government-general. This was influenced from a Baroque urban planning method that was applied to urban planning in various major cities of Europe in the late 19th century, and applied to urban planning in Daegu, Daejeon, and Pyongyang in Korea at that time.
 3) In other words, Gunsan urban planning (1938) is one of the cases in which this urban planning method was applied by the Chosen Government-general. According to previous studies, it is widely believed that Chosen's urban planning during the Japanese colonial period were made by the Chosen Government-general. However, as a result, the Gunsan City Government created the Gunsan urban planning map before the Chosen Government-general doing, which was applied to the final draft. In addition, the Gunsan City Government and the Chosen Government-general exchanged detailed opinions to decide the final draft. In other words, the Gunsan urban planning (1938) was not a one-sided urban plan by the Chosen Government-general, and part of the Gunsan City Government's opinion was reflected in the final plan.
