Kitsune (狐) is the Japanese word for fox. Foxes are a common subject of Japanese folklore; in English, kitsune refers to them in this context. Stories depict them as intelligent beings and as possessing magical abilities that increase with their age and wisdom. Foremost among these is the ability to assume human form. While some folktales speak of kitsune employing this ability to trick others—as foxes in folklore often do—other stories portray them as faithful guardians, friends, lovers, and wives.
