The diet of introduced raccoon dogs (Nyctereutes procyonoides albus) was examined by fecal analysis in early autumn on Okushiri Island, Hokkaido. A total of 39 feces were collected from 37 latrines in September 2021 and analyzed using the point frame method. The most common foods of raccoon dogs were insects (frequency 100%; mean occupancy 47.1%) and fruits (frequency 87.2%; mean occupancy 30.8%). The insects were mainly Coleoptera (frequency 100%; mean occupancy 35.2%), of which the occupancy was higher in this study than previously reported from other regions. High predation pressure of the alien raccoon dog might have a negative impact on insect communities.
