A series of 3 direct-type earthquakes with magnitude ≥6 occurred in the Kumamoto Prefecture, located in the western area of Japan, between April 14 and 16, 2016. Children with food allergies (FA) had difficulty procuring allergen-free meals during this period due to the infrastructure shutdown. We investigated the status of children with FA during the 2016 Kumamoto Earthquake and their behavioral changes after the disaster. We conducted a survey of the parents of 59 children with FA (median: 4 years and 1 month old) who were clinically followed up at our institution. They were questioned about their behavior change to allergen removal and using allergen-free foods during the disaster. Forty-seven (79.7%) children with FA were evacuated immediately after the earthquake and returned to their homes after the restoration of lifelines. Most stayed in their cars, while a few took shelter at public evacuation sites. Thirty-eight children (64.4%) had difficulty obtaining allergen-free food, and 29 children with FA (49.2%) did not have a stockpile at home. Thirty-three children with FA (55.9%) consumed allergen-free foods acquired primarily through relief supplies. Forty-seven guardians (79.7%) insisted that stockpiling allergy-friendly foods at home should be a part of future disaster planning. Stockpiles of allergen-free food were not sufficient in most households. Awareness of self-stockpiling allergen-free foods, reassessing public stockpiling, and establishing a system to provide information regarding relief supplies to evacuees outside evacuation centers are important for disaster planning in children with FA.
