Due to the heavy rain from August 9, 2022, the Nakamura River, which flows through Ajigasawa Town, Aomori Prefecture, overflowed, causing flood damage exceeding 1 m. A nursery school was flooded up to 0.75m above the floor, and 47 children evacuated to a nearby elementary school by bus and on foot. Evacuation was carried out for about 30 minutes from 11:00 immediately after the evacuation order was issued. Even on the day of the disaster, an alternative nursery school was considered, and after the emergency nursery school, the nursery school was continued using the public hall. Based on interviews at the nursery school, we sorted out the problems of evacuation behavior and childcare continuity. In addition, after reproducing the progress of the flood in the urban area based on the flood trace survey around the nursery school and the flood inundation analysis of the Nakamura River, it was verified whether the evacuation route and evacuation behavior were appropriate.
