History & Causes of Extinction

Hokkaido Wolf

During the famous Meiji Restoration in Japan, the local farmers expressed their interest for having their own American-style ranches to raise livestock. During this time, a US farmer named Edwin Dun began importing livestock to Japan.

Soon after, the local Hokkaido wolves began preying upon these livestock, and they experienced significant development during this period. The owners took to killing these carnivores using strychnine poison since they posed a direct threat to their livestock. Incidentally, the Meiji government also promoted and supported this at the time.

Another theory suggests that, in 1878, a large population of wild deer and other minor herbivores starved to death because of the unavailability of natural vegetation. This, in turn, had a severe negative impact on these wolves, since they had to depend upon them for survival. A bounty was also placed on the wolf, but it officially became extinct in 1889.

Hokkaido Wolf Sightings

Since its extermination, there have been several reports from people claiming to see the animal. However, these sightings have never been verified. One theory also suggests that, the animals that have been seen or heard howling were nothing but a wolf-dog hybrid.

Physical Description

Hokkaido Wolf Size

By size, dimensions, and other features, the physical characteristics of the Hokkaidos were closely related to the modern-day standard gray wolf. The skull/head was quite large and robust, with the jaws lined with long, curved canines as an adaptation to having a good grip on the prey. Their coat was usually light grey to tannish grey in color, with dark guard hairs running along their back. The wolves stood about 70–80 cm at the withers. They were generally very lean, but had an exceedingly muscular body.


Like most other wolf species, these carnivores were chance predators that would prey in packs. This behavior assisted them in predating the livestock of the Japanese farmers. They were nocturnal and would be active between dusk and sunrise.


The primary prey of the Hokkaido wolf were deer, rabbits, birds, and other small to medium-sized animals.
