This report presents a pilot attempt to structure health- and welfare-related content in Koho Iitate, the official municipal public relations bulletin of Iitate Village, Fukushima Prefecture, as a knowledge graph and thereby facilitate its interpretation. The idea originated in the 2025 “Fukushima Reconstruction Knowledge” field-learning program, in which the author participated with students from Yamaguchi University, who consulted the bulletin as a local documentary source. Koho Iitate is publicly accessible on the village website in PDF format and constitutes a valuable archive of textual records. For this pilot, data were extracted primarily from health- and welfare-related pages and divided into three recovery phases: evacuation, return, and the period following the lifting of evacuation orders in the designated reconstruction base area. The extracted information was classified into six node types (Topic, Activity, People, Place, Value, and Risk) and the relationships among them were organized as a network. A preliminary reading suggests a possible broadening of health-related discourse: from responses to radiation-related concerns and anxiety, through livelihood reconstruction and social reconnection, toward everyday well-being encompassing child-rearing, support for older adults, participation, and a sense of security. By treating municipal public relations materials as an official narrative through which the municipal government articulates desirable forms of everyday life, this report presents the pilot as a practical attempt to transform local archival materials into machine-readable knowledge resources
