We studied the food habits of the Japanese marten (Martes melampus) and the raccoon dog (Nyctereutes procionoides) at the Tama Forest Science Garden, western Tokyo, Japan by fecal analysis in 2014/15. Martens were dependent on fruits throughout the year and showed less marked seasonal changes. Raccoon dogs were less dependent on fruits than martens were, and more dependent on mammals in spring, insects in summer and winter, and seeds throughout the year. Martens fed on more fruits containing tiny seeds, such as Actinidia arguta and Stachyurus praecox, whereas raccoon dogs fed on more large-seeded fruits, such as Ginkgo biloba and Diospyros kaki. Martens fed on more fruits that grew at the forest edges, whereas raccoon dogs fed on more fruits growing inside the forest.
