This paper examines the collection of Joseon legends published during the Japanese occupation. The analysis focuses on the characteristics of the legendary categories and category settings applied to the Legendary collection. First of all, the name and terminology of legend are considered. As a result, the name legend has been used in Joseon society for a long time, and it is also confirmed that it is used close to the legend in the classification of tales today. However, considering the series of situations identified in the Japanese colonial period, this did not seem to lead to the modern Korean academic system. In 1913, Chosun Government-General published a report entitled “Legendary Fairy Tale Survey” by examining legends and fairy tales across Korea. Old stories are collected in large quantities, and the collection of materials is named Legend , and the category of Joseon legend is very limited. Since then, more than 10 books on Joseon legends have been published. And the legendary category established by Chosun Government-General spreads throughout the Japanese occupation. In the process, the perspective of recognizing Joseon mythology as a category of legend is also understood. These points are noted in connection with the legendary book published by the Koreans and the future of the legend that will walk the path of popularization.
