Kashimo, a mountain village in Gifu Prefecture, may have a population of less than 1,000 by 2050. Although the population of Kashimo is declining, the area is unique in that many young people are coming to Kashimo to take part in activities through regional university cooperation projects. As someone who has actually participated in activities in Kashimo, I propose a university as a center for co-creation by all people involved in Kashimo.
