The Japanese raccoon dog (Nyctereutes procyonoides viverrinus), also known as tanuki (狸 or たぬき?) in Japanese, is a subspecies of the Asian raccoon dog.

Researchers[who?] have suggested that they be considered a separate species, N. viverrinus, or that raccoon dogs of Japan could be further divisible into separate subspecies as N. p. procyonoides (hondo-tanuki) and N. p. albus (ezo-tanuki), but both views are controversial.

As the tanuki, the animal has been significant in Japanese folklore since ancient times. The legendary tanuki is reputed to be mischievous and jolly, a master of disguise and shapeshifting, but somewhat gullible and absentminded. It is also a common theme in Japanese art, especially statuary.
