I conducted a mammal fauna survey using a camera trap in Iryuda, Odawara City, Kanagawa Prefecture, from April 2020 to May 2021. Cameras set at 10 sites took a total of 2,500 photographs of eight species of middle to large mammals and unidentified species of Rodentia Muridae and Chiroptera. The most photographed species was Sus scrofa, followed by Paguma larvata, Nyctereutes procyonoides and Cervus nippon, in this order. In correlation analyses of relative abundance index (RAI) between eight taxa (seven species and Muridae) that were photographed at more than seven sites, the correlation between S. scrofa and C. nippon was especially high and the correlations between Mu. itatsi and Muridae, and between Me. anakuma and Muridae, were present. Several species pairs showed negative correlations, such as between Mu. itatsi and P. larvata. Correlations of RAI between species could partly reflect the similarity of habitats and strength of competition between species.
