概要	The oral history method is a qualitative research approach in which researchers conduct in-depth, recorded interviews with individuals who have direct personal experience of a historical event, social process, or community life. It captures subjective perspectives, memory, and lived experience that written records rarely preserve, making it indispensable for recovering voices absent from official archives — particularly those of marginalised communities, minority groups, and ordinary people.	Historical archival research is a systematic method of investigating the past through the critical examination of primary source documents preserved in archives, libraries, and institutional collections. Researchers locate, access, authenticate, and interpret original records — such as government documents, correspondence, diaries, maps, and institutional files — to reconstruct events, trace processes, and build evidence-based historical arguments. It is foundational to historiography and widely applied across humanities and social science disciplines.
