The importance of community attitude and participation for the success and sustainability of cultural festivals has been steadily increasing in recent years. The Chuncheon Puppet Festival (CPF) is an international festival that has been held every year since 1989 in Chuncheon, Korea. The festival has several distinctive characteristics as a sustainable event because: (a) it maintains its single genre of puppet performances based on modern cultural art; (b) it is well-established as the festival for the local residents of Chuncheon City and is planned by local community residents and local small companies, not by government agencies or global large entrepreneurs; (c) it helps children to have an interesting cultural experience in the local environment; and (d) it is regularly hosted in August, an off-season for festivals in Korea that was chosen by residents as it is a school holiday season. However, there is still room for improvement to secure its place as a successful sustainable festival. The following might be considered: (i) increased exchange of human resources among the festival executive members, community groups, and the public staff in Chuncheon City; (ii) local residents should maintain full control of the festival; and (iii) a local cultural trust should be established by cultural art professionals, local resident organizations, puppet show professionals, and public agency staff. The CPF is a typical example of a successful sustainable festival with proactive and supportive community participation and a large number of volunteers that help to increase local competitiveness and sustainable local development. This case report delivers insightful lessons and messages to guide what needs to be preconditioned for local cultural festivals to be sustainable and successful for a long time in many destinations, where they can contribute as efficient catalysts for regional tourism development.
