The Japanese Wolf refers to two extinct subspecies of the grey wolf ( 狼 or おおかみ ōkami).
The subspecies that the name 'Japanese Wolf' usually describes is the Honshu Wolf (Canis lupus hodophilax; 日本狼 Nihon ōkami), which occupied the islands of Honshu, Shikoku, and Kyushu in Japan. It is thought to have become extinct due to a combination of rabies, which first occurred in the islands in the 17th century, and human eradication. The last known specimen died in 1905, in Nara Prefecture.
There are currently eight known pelts and five stuffed specimens of the Japanese Wolf in existence: one stuffed specimen is in the Netherlands, three are in Japan, and the animal caught in 1905 is kept in the British Museum. Owing to its small size (the Honshu Wolf is the smallest known variety of wolf, probably due to allopatric speciation / island dwarfing) the Honshu Wolf's classification as a subspecies of the grey wolf is disputed.
The other endemic wolf of Japan was the Ezo Wolf (Canis lupus hattai; 蝦夷狼 Ezo-ōkami), also known as the Hokkaido Wolf, which occupied the island of Hokkaido in Japan. The Ezo Wolf was larger than the Honshu Wolf, more closely approaching the size of a regular grey wolf. The Ezo Wolf reportedly became extinct in 1889 as a result of deliberate strychnine poisoning by farmers.
The Japanese Wolf was afforded a benign rather than malignant place in Japanese mythology and religion: the clan leader Fujiwara no Hidehira was said to have been raised by wolves, and the wolf is often symbolically linked with mountain kami in Shinto (the most famous example being the wolf kami of Mitsumine Shrine in the town of Chichibu in Saitama Prefecture).
Sightings of the Japanese Wolf have been claimed from the time of its extinction to the present day, but none of these have been verified (see cryptozoology).
