The importance of preserving intangible cultural heritage (ICH) for sustainable development has been widely acknowledged by the international society. Various forms of cooperation have taken place to prevent deterioration and destruction due to its inherent characteristic of ‘intangibleness’. Public engagement, however, has largely been excluded from the system in spite of its significance in safeguarding ICH by inducing people to be trained as successors. In this respect, this paper discusses and emphasises the necessity of public engagement in safeguarding ICH. To this end, it suggests the use of digital technologies to create museum content to encourage public involvement with and learning about ICH. Focusing on ICH in Korea, digital exhibitions on Jultagi and Daemokjang utilising virtual reality technology are proposed. The ultimate aim of this article is to contribute to the sustainability of world ICH for humanity through digital exhibitions.
