In Japanese, a nine-tailed fox is referred to as "Kyūbi no Kitsune" (九尾の狐). The word "Kyūbi" means "nine tails," and "Kitsune" is the Japanese word for fox. This term specifically describes the mythical fox entity that has achieved the maximum level of power and wisdom, symbolized by its nine tails. The nine-tailed fox, is a prominent figure in Japanese folklore. These mythical foxes are believed to possess high intelligence, long lives, and magical powers. The most extraordinary among them are said to gain multiple tails as they age, with nine being the maximum. Kitsune are often depicted as tricksters, with motives that vary from mischievous to malevolent. However, they can also act as guardians, friends, lovers, and wives. Their ability to transform into human form is a key aspect of their lore, often deploying this ability to form bonds with them.

One of the most significant roles of Kitsune in Japanese mythology is their connection to Inari, the Shinto deity of rice, prosperity, and fertility. Kitsune are considered Inari's messengers and servants. In this context, they are often portrayed as benevolent, protecting Inari's shrines and worshippers. Kitsune associated with Inari are typically depicted as white, a color symbolizing good spirits in Japanese culture.

Inari's shrines, scattered throughout Japan, often feature statues of foxes, reflecting the Kitsune's revered status in relation to this deity. These statues and the associated folklore underscore the deep cultural and religious significance of the Kitsune in Japanese tradition.
