Abstract
Since an exhibition titled 'The 1st Children's Formative Paradise' was held in 1958 in the city of Toyohashi, Aichi Prefecture, many similar exhibitions have been held in various places across Japan. However, even the basic data, for example, as to where such exhibitions were actually held, have not been clarified so far. Therefore, the author carried out an investigation into this matter. The results revealed that open-air exhibitions of formative art works were not the activities limited only to some specific times or regions, but the activities having an everlasting significance even now. At the same time, it was also clarified that such exhibitions were always attended by a criticism that they were a kind of show using children's works. However, the author believes that just in this point, there lie further potentialities of open-air exhibitions of formative art works.
