This document summarizes Makoto Okada's capstone project on developing dementia-friendly communities in Japan. The project involves finding insights through field research, prototyping concepts by mapping stakeholders across sectors, developing relationships through activities like study groups, connecting these ideas and relationships to generate recursive projects, and ultimately utilizing the connections to create tools and strengthen the social ecosystem for dementia issues in Japan. The five-step process focuses on developing multi-layered relationships through a series of activities, relationship building, and innovative mediation.
