Seong Dae-jung , who participated in the 11th Tongsinsa of the late Joseon Dynasty(1763) , demonstrates various perceptions of Japan through ~ 日本錄~ (Il bonrok) and ~춤城雜 記~ (Cheongseongjapgi). Seong Dae-jung overcame the limitations of his status as child of a concubine and established his own awareness of the country of Japan by interacting with various scholars. Seong Dae-jung , who had more vivid knowledge of Japan than anyone else under the pride that he has been involved in the "Tongsinsa" from generation to generation, found information about Japan and learned about it by reading the previous book. In addition, after visiting Japan he developed a sense of foreign countries by listening to the vivid stories of various people who had been to China as members of the ‘ Yeonam Group'. As seen above, ~홈城雜記~ (Cheongseongjapgi) is a book containing miscellaneous records, and various records related to Japan can be found. He mentioned "geumsi(今市)，" a place from the Japanese fiction "Samrangjeon," which was popular in Joseon at that time, and introduced "野談" of Japan (an unofficial historical tale) in order to directly reveal his hostility toward Japan after the Japanese Invasion of Korea in 1592. In addition, he wrote an interesting description of the first encounter between Ryu Seong-ryong and Admiral Yi Sun-sin, and described absorbingly the performance of Yi Sun-shin, who played an essential role in the Japanese War. As such , it was confirmed that in W 좁城雜 記Jl (Cheongseongjapgi) there were many records that were difficult to leave in the official works such as "Ilbonrok". In addition, there is a great literary significance since there are either some essays containing fictional factor like ghost stories which are related to the Japanese Invasion of Korea in 1592 , or unofficial tales that are difficult to appear in history.
