Abstract
In Japan, amid efforts to build an inclusive society, reflecting disabled individuals' perspectives in policy and design is increasingly vital. This study qualitatively analyzed a case where parents of children with cerebral palsy influenced government policy, clarifying social innovation processes through inclusive design. Two practical frameworks were developed—a stakeholder-led approach and a collaborative public-sector model—demonstrating their effectiveness in reducing information asymmetry, promoting policy co-creation, and enabling direct participation by stakeholders in policy formation.
