here's its wikipedia description:
In Japanese folklore, kitsune, are foxes that possess paranormal abilities that increase as they get older and wiser. According to yōkai folklore, all foxes have the ability to shapeshift into 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, and lovers.
Foxes and humans lived close together in ancient Japan;[citation needed] this companionship gave rise to legends about the creatures. Kitsune have become closely associated with Inari, a Shinto kami or spirit, and serve as its messengers. This role has reinforced the fox's supernatural significance. The more tails a kitsune has—they may have as many as nine—the older, wiser, and more powerful it is. Because of their potential power and influence, some people make sacrifices to them as to a deity.
Conversely foxes were often seen as "witch animals", especially during the superstitious Edo period (1603–1867), and were thought of as goblins who could not be trusted (similar to some badgers and cats).
