Abstract: This paper discusses lion dances as an example of shared heritage. In the local communities of Japan, there are several thousand lion dance troupes. These types of performances, where the dancers don animal costumes, can be found in various locations across Asia. While the dances are similar in shape, they vary in meaning, religious background, music, style, etc. Such differences are a manifestation of diversity. As such, when considering shared heritage, it is important to recognize the aspect of diversity. Japan has never made a multinational nomination to the UNESCO’s List of Intangible Cultural Heritage (ICH). The reason for this lies in Japan’s method of selecting candidate properties for nomination. That is, Japan abides by a unique policy of selecting candidate properties from among those designated as cultural properties by the national government. “Cultural properties” refer comprehensively to the system for safeguarding cultural heritage in Japan and can be designated not only by the national government but also by local administrative units such as prefectures and municipalities. However, only nationally designated cultural properties have so far been eligible for nomination as a UNESCO’s List of ICHs, and the national designation criteria include no requirement to consider international compatibility. The designation criteria of local governments include no such requirement, either. In other words, as long as Japan’s criteria for selecting candidate properties for nomination to the UNESCO’s List of ICHs conform to the domestic criteria for selecting cultural properties, making a multinational nomination would continue to be extremely difficult. Under the present system, responding to proposals from other countries would also be difficult. Yet, I have hope. In 2021, the cultural properties system for ICH in Japan was slightly modified. In place of the conventional system of designation, a system of registration was adopted with respect to intangible cultural heritage to provide more flexibility in safeguarding a wider scope of properties than ever before. Such a new system might promote the awareness of the need to take a more international perspective. At the same time, views that Japan should strive to make multinational nominations are emerging within discussions about UNESCO’s List of ICHs. When considering such trends, the prospect of Japan making multinational nominations or responding to proposals from other countries may be realized in the future. Thus, in this paper, I wish to discuss what types of multinational nominations would be possible, based on case examples of folk performing arts, my specialty area. It should firstly be noted, however, that there are two categories of performing arts in Japan, namely traditional performing arts and folk performing arts. Traditional performing arts are fundamentally performed in theaters by professional performers. There are also amateur performers of traditional performing arts, who generally study under a specific master. Folk performing arts, on the other hand, are fundamentally performed by amateur performers within a specific event held in a particular region. Most are linked to faith and have been inherited through festivals and annual events. In placing them under the domestic system for safeguarding cultural properties, traditional performing arts are judged by their artistic and historical value, and folk performing arts are evaluated mainly by their folkloric value (stipulated by law as performing arts that show transitions in lifestyles). A large number of folk performing arts exist in Japan. As of 2020, as many as 8443 properties, including festivals and annual events, have been nationally or locally designated for safeguarding as intangible folk cultural properties. When including properties that have not been designated, more than several tens of thousands of performing arts are thought to exist. These folk performing arts have emerged from diverse historical contexts and are further classified into a number of subcategories. Among these performing arts, I wish to focus on Lion Dances, or “Shishi-mai.” I must, however, confess that I am regrettably not well-versed in the intangible cultural heritage situation in East Asia as a whole. I, therefore, wish to apologize in advance that the case examples I present herein are not necessarily common to all countries in East Asia.
