This study aims to analyze the regional differences of respondents on the image of food in Busan and the influence of the image of restaurants in Busan on the tourism motivation and participation intention from July 15 to August 25, 2021, targeting tourists who want to do marine tourism in Busan. As a result of the study, First, the image of food in Busan region was different according to the residential area of the respondents. On national wide of average, the food image of Busan such as grilled stomach chain, Nampo-dong food street & Jokbal Street was high. Second, the image of restaurants in Busan will have a positive effect on the tourism motivation, which shows that the reputation and the quality of food factors do not have an effect. This may be because the quality of food is lower than other regions, which means that the reputation is lower. Third, the marine tourism motivation will have a positive effect on the participation intention. Food and shopping were adopted, and experience and learning were rejected. This reason suggests that many tourist attractions centered on many oceans and cities can experience tourism, but there is not enough place to hand on experience to related learning.
