In recent years, heat stroke and infectious diseases have become problems, and decentralized evacuation is required as a measure to alleviate the problems of overcrowded shelters. One of the options during a decentralized evacuation is the use of Accommodations. The aim of this study is to clarify the process of realization and the actual situation of using accommodations as evacuation shelters in Nachikatsuura Town, Wakayama Prefecture, where the use of accommodations during disasters was realized through the efforts of local residents. The fact that both residents and accommodations shared the experience of the disaster led to the realization of the agreement. Since then, the town has taken over and developed the agreement to prepare for disasters by utilizing local resources.
