Masks have been passed down all over the world, which is a cultural achievement, a cultural similarity, and a symbol of the shared dream of humankind. In other words, masks are a DNA of human culture. In this regard, the mask is a cultural tool that best reveals the cultural diversity that UNESCO pursues. There is nowhere that masks do not exist, masks are everywhere. The mask contains many historical traditions common in human lives. Masks and the mask culture have existed all over the world. However, IMACO is the only NGO organization accredited by UNESCO in the field of masks. Since its establishment, IMACO has regularly held a number of international conferences and proposed to create the World Mask & Symbol Map. This map shall chart the symbols of the masks to reveal the very DNA of human culture, collecting world masks that contain the characteristics of each culture and cultural symbols that humanity has accumulated. In addition, IMACO has held numerous domestic and international symposiums related to masks. Protecting the mask is to acknowledge cultural diversity through masks, which are a crystallization of the cultural symbols. It is a valuable work for understanding human culture and for sustainable development. IMACO aims to protect the rapidly disappearing mask culture by building archives of masks and mask culture for the people of the world. IMACO will establish an international network of mask craftsman, actors, museums researchers, festivals, and related governments, and expand their objectivities and activities, IMACO will cooperate with UNESCO to contribute to the values of world peace and human life culturally. IMACO will continue to actively participate in UNESCO’s itinerary to faithfully fulfill the values of cultural diversity and to help improve the quality of human life through culture. As an accredited NGO by UNESCO, we promise to do our best to globalize this intangible cultural heritage with all our will and passion in our mask culture project that will become a basis for future generations.
