Abstract
This study explores the impact of collaboration between outsiders and locals in creating a children’s place in Atsuta ward, Ishikari city, Hokkaido, where play opportunities are limited due to depopulation and geographical challenges. “Atsumin” was established to foster children’s creativity through interactive activities, with workshops by outsiders introducing new knowledge and skills. We found that outsiders' roles varied based on their involvement with the community, which was visualized in a diagram. Active parental participation ultimately drew support from the broader local community.
