We sought to calculate the extra social costs resulting from child abuse in residential care facilities (RCFs) for children with disabilities (CWD) in Japan. We distributed a survey to 260 residential facilities for CWD in 2020 and obtained responses from 91 facilities. Among the children placed in these facilities, our estimates by four different criteria determined that 23-67% were affected by child abuse. We also estimated extra costs for each of the four criteria, which we estimated to average USD 647.7 million. This study is meaningful in that there are no existing official statistics or research findings on the extra costs of residential care due to child abuse in Japan.
