Considering the health effects of radiation accompanying the nuclear power plant accident that occurred in the wake of the Great East Japan Earthquake, this study aimed to examine social participation after the disaster and factors hindering participation among citizens aged ≥ 65 years from designated evacuation zones inside the Fukushima prefecture. The target population comprised 180,604 residents in 13 municipalities containing designated evacuation zones. There were 73,433 valid responses (response rate, 40.7%); of which, data from 19,573 respondents aged ≥ 65 years were analyzed. Multinomial logistic regression analyses were conducted to investigate the factors associated with social participation. In total, 53.0% of older evacuees did not participate in recreational activities or communal services. Stratified analysis showed that living outside the Fukushima prefecture and requiring assistance with activities of daily living were associated with low social participation. This study clarified that the majority of older evacuees did not participate in social activities at the time of the survey within one year of the disaster. Furthermore, where these older individuals were evacuated to and whether they were able to live independently might have affected their social participation. Better subjective health, better sleep quality, and more frequent exercise may be associated with improved social participation.
