Three organizations collaborated on an international exchange exhibition to introduce Art Brut artists from Japan and Belgium. The organizations involved were Kunsthuis Yellow Art in Geel, Belgium; Museum Dr. Guislain in Gent, Belgium; and the Social Welfare Organization Aiseikai based in Nakano City, Tokyo. Taking place at the Museum Dr. Guislain, the exhibition featured highly original works by 17 Japanese artists and 18 Belgian artists with mental disorders or intellectual disabilities. An additional international exchange project saw the exhibiting artists from Japan and Belgium engaging in an airmail-based exchange. This exchange gave the artists the opportunity to have contact with each other’s forms of expression, personas, and cultures through the words and pictures they put down on postcards. The postcards from this project were displayed along with the other works at the museum. The exhibition attracted visitors with and without disabilities of different nationalities and ages, principally from the EU.
