he upheaval and extinction faced by traditional culture is a core issue in today’s world. It has brought us to the realization that we are living in an important transition period where the future of humanity will be determined. In particular, the advent of digital platforms has provided a communication channel to link people together; the importance of these platforms seems poised to become much greater. In this era, in which means of communication are facing remarkable qualitative changes, oral tradition is under considerable threat. In past eras where humankind created languages and memories to resolve all kinds of issues and share information, speech was a way to achieve totality. Through speech, people delivered their thoughts and opinions, created new things, and embraced differences to become one. As such, spoken language became an absolute means and solution to maximize the immense capacity of humankind. People discovered interests and meanings through conversations; they combined work and enjoyment by singing; they wore masks and gave movement-based performances accompanied by amusing anecdotes. By reciting and dedicating bonpuri, a ritual song to pray to deities and receive oracles, their creations became content passed down through oral culture.

Intangible cultural heritage (ICH) refers to the non-physical aspects of cultural heritage. We can preserve tangible cultural heritage, such as buildings and artifacts, to pass them down to the next generation. It is, however, difficult to determine what specifically should be preserved when it comes to ICH. Generally, ICH elements are selected and then practitioners of the arts or skills are designated to preserve and transmit the elements. The essence of ICH preservation, therefore, is to transmit the arts and skills of ICH from people to people and from generation to generation.
