概要	Participatory Case Study is a qualitative design that embeds participatory principles within a bounded case study framework. Participants are not merely research subjects but active collaborators who co-define the research questions, co-generate data, contribute to analysis, and validate the findings. The approach is appropriate when deep understanding of a specific, bounded context is needed and when the community or group under study has both the capacity and the right to shape the knowledge produced about their own situation.	Case study research is a qualitative research design that investigates a specific phenomenon, individual, group, organisation, or event in depth within its real-world context. Systematised by Robert K. Yin in 1984, it supports single-case and multiple-case designs and draws on multiple data sources — interviews, observation, documents, and artefacts — to build a rich, contextualised account of a bounded unit.
