The term refers to two extinctsubspecies of the Gray Wolf. The subspecies that the name 'Japanese Wolf' usually describes is the Honshū Wolf , which occupied the islands of Honshū, Shikoku, and Kyūshū in Japan. The other is the Hokkaido Wolf. The Honshū Wolf is thought to have become extinct due to a combination of rabies, which was first reported in Kyūshū and Shikoku in 1732, and human eradication. The last known specimen died in 1905, in Nara Prefecture.
