Visionary art, naive art, primitive art, folk art – outsider art can be all of these. And the 'outsider' tag reflects its audience as well as its practitioners: you don't need any theoretical knowledge of art to find it engaging. The Wellcome Collection's 'Outsider Art from Japan' exhibition brings together more than 300 exhibits, including ceramics, textiles, paintings, sculpture and drawings, by 46 artists, all of whom are residents and day patients at social welfare institutions on the main island of Honshu.
