This study analysed tourism system described in Yorha Diary, which was written by Ji-won Park in the late Choson Dynasty during the 18th century. Yonam``s motivations of the tour to China were the desire to trip to China as a realistic intellectual, the desire to learn culture and institutions of Ching Dynasty, and the desire to communicate with Chinese distinguished persons for academic exchange. His trips were done on the basis of his thorough preparation, critical intention for learning, active investigation of Chinese environment, and methodological understanding. Tourism thoughts described in Yorha Diary were realization of trips to China and realistic attractions. His realistic approach was realized by his application of bricks for construction of houses and fortification after coming back to his country. The motivations and purposes of Yonam`s trip to China were clear and his trip styles and attitudes were also active. All through his trips, his concerns were focused on realistic applications of materials. These characteristics mentioned above so far show that he is not only the greatest intellectual at his time but also a real tourist who had abundant knowledge and oral and written fluency. In this vein, Yorha Diary, as a representative tourism record in the late Choson Dynasty, should take a remarkable position in Korean traditional tourism history, in a sense that it recorded tourism and tourism phenomena realistically.
