This paper provides the analysis of the altered qualifications of students, who participated in ten community development workshops of Sakai-city 2022 for the problem-solving type of regional planning, in terms of eight competencies. The results indicate marked improvements in the six competencies, such as the “system thinking”, “strategical”, “self-awareness”, “integrated problem-solving”, “normative”, and “coactive” elements. The effective methodology was drawn by analyzing the contents of the workshops that brought about the alteration of the six competencies. The educational effects of the methodology were also confirmed in the research conducted three months after the workshop.
