概要	Multiple case-based oral history is a qualitative research design that embeds oral history interviews within a multiple-case framework. Rather than collecting testimonies from a single community or site, the researcher deliberately selects two or more distinct cases — communities, cohorts, organisations, or geographic sites — gathers in-depth oral testimonies within each, and then conducts systematic cross-case comparison to identify both shared and divergent historical experiences.	Oral history is a qualitative research method that collects, preserves, and interprets first-person spoken accounts of past events, experiences, and social processes. By recording in-depth interviews with individuals who witnessed or participated in historical events, oral historians document perspectives that written records often exclude. The method bridges historical scholarship and social science, treating the narrator's memory, subjectivity, and voice as primary evidence rather than as limitations to be corrected.
