Popular name for certified people with high levels of artistic skill who take part in performing arts such as Noh plays that are classified as important intangible cultural heritage by Japan's minister for education, culture, sports, science and technology. The formal name is "holders of important intangible cultural heritage (individual recognition)." For certification, they are required to have many achievements, including teaching younger people. Members of groups certified as highly skilled performers (e.g. Noh actors in the Japan Noh Association) are called "holders of important intangible cultural heritage (collective recognition)," but they are not usually called "living national treasures."
