The Japanese Folk Arts Movement 日本民芸運動 (Nihon mingei undō) was founded in the mid-1920s. It was originally composed by a small group of craftsmen grouped around the art theorist Yanagi Muneyoshi 柳宗悦 (1889-1961). The Movement attracted a dense network of supporters; it grew and quickly became national in scope. In the 1930s, an association and a museum followed the first exhibitions. With renewed public success, the Movement, which maintains complex relations with Japanese ethnology, continued to develop after WWII. It is an important milestone in modern discourse on Japanese aesthetics, a locally avant-garde structure in the study of folk material culture and a pioneering organization in the preservation of arts and crafts know-how.
