With the recent rapid increase in the number of Koryo-people in Korean society, issues such as Korean society's views and stereotypes toward Koryo-people, their maladaptation to society and culture, and consequent non-participation in leisure activities require academic attention. The purpose of this study is to understand leisure constraints experienced by Koryo-people who migrated to Korea and the process of overcoming them. In order to achieve this purpose, this study used theoretical sampling, and in-depth interviews were conducted with 15 Koryo-people residing in Korea in November 2020. Grounded theory approach was used which consisted of open coding, axial coding, and selective coding. The concepts derived from the interviews were grouped into 37 subcategories. As a result of classifying subcategories, a total of 13 upper categories were presented: daily stress, maladjustment to life in Korea, inappropriate perception of leisure, COVID-19 situation, stress as a Koryo-people, willingness to overcome leisure constraints, intrapersonal constraints, interpersonal constraints, structural constraints, behavioral negotiation strategies, cognitive negotiation strategies, maintaining work life balance, and social adaptation. The core category was analyzed as participation in leisure activities through negotiation strategies and willingness to overcome perceived constraints.
