This study is about the wedding culture of Seoul and Kyungsangdo. This paper is a qualitative study that is based on interviews. As a result of this study, it became clear that before the industrialization of South Korea, there were different characteristics of wedding culture in each region. However, the unique characteristics of wedding customs in each region have been degenerated or exterminated, in tandem with the influx of customs from other regions, due to the dramatic urbanization of South Korea, and the development of transport and communication that appeared in the process of modernization. Furthermore, wedding customs were transformed from ceremonies based on a regional and kin-based community into those that were no more than mere events, which was derived from the industrialization and urbanization of Korea.
