The Shikoku is from the Shikoku Island in Japan and they are very much like the Japanese Shiba Inu. There are six native Japanese dog breeds and the Shikoku is medium sized and sits in between the smaller Shiba Inu and the very large Akita Inu. All of the Japanese native breeds are members of the Spitz family. The Japanese have sorted their six breeds into 3 categories by size. Being medium size, the Shikoku is a member of the Shika-inus group. Others in this group are the Ainu Ken, the Kai Ken and the Kishu Inu. There are small differences between the three dogs in the Shika-inus group.
The Shikoku was bred to be a hunting dog in Kochi Prefecture to hunt boar and deer. Other names for the breed include Kochi-ken and Kishu dog or boar hound. This dog is considered to be the purest of the Japanese native dogs or Nihoken. They are today very , very rare. There are very few outsides of Japan, but some in North America are attempting to save the breed.
The are od Kochi Prefecture is a mountainous region with rough terrain that anyone outside of the area would have a hard time accessing. That is why the Shikoku is considered to be so pure as they were pretty well isolated in the mountains. The breeders were also isolated by the mountains and there was very little interbreeding. Although breeding the same dog, these different groups developed different lines of the Shikoku.
Documentation tells us that the number of originals lines was just two and these were the Western and Eastern Shikoku. The Western dog was known as the Mount Ishizuchi Shikoku and the Eastern as the Mount Tsurugi Shikoku. Within these two lines of Shikoku there are additional strains.
Within the Eastern line there is the Tokushima (lya) and the Koci-Aki strains. Within the Western line there is the Hata Uwahara, the Ehime-ken Shuso-gun and the Honkawa. Among these lines and strains, there are different coats and different colors; some heavier and some taller, but all figure into the development of the breed.
Finally, in the Showa Era the Japanese established the Dog Protective League and they began collecting the native dogs from around the country. They protected them so that the breed will go on. The Shikoku is today recognized as Foundation Stock by the AKC and it is fully recognized by the Japan Kennel Club, the Canadian Hound Club and the Shikoku has been declared a living Japanese “natural monument”.
Two bloodlines became the way the Shikoku were know after the war – the Honkawa and the Hata lines The Honkawa line were the descendants of the Choshun-go and the Hata line were the descendants of the Matsukaze-go. They bred the lines separately until 1955, when they mixed them to make the breed stronger. They are no longer considered separate in any way.
Because they are such primitive dogs, the Shikoku are good watch dogs and quite reserved with strangers. They need a lot of socialization to be a family pet but once they are, they make great companions. Intelligent, quick to learn and eager to please. Of the two lines of Shikoku dogs from the Western strains, the current Shikoku owes much of its current development to the Honkawa and Hata strains.
The Sanshu was developed in Japan a century ago – in 1912 in fact.
It is a cross between the Chinese Chow Chow and the ancient Japanese Aichi. People who know these dogs say they bear a resemblance to other Inu breeds, but it has a straight tail and not the usual curved one that you'd expect.

Today’s Shikoku is a medium sized breed with a Spitz like body – square with a head that is wedge shaped. The ears are pointed, and the tail is curved and feathered. They have arched toes and hard pads with dark, hard nails.
The two lines of the Shikoku are slightly different in built and look. The Honkawa strain is slender and athletic; agile and single coated. They have dark eyes and most of them are black and tan.
On the other hand, the Hata strain is much heavier boned, with the front more muscular than the rear. They have small ears, a wide skull and a strong undercoat. His eyes are shaped differently than the Honkawa. Their coats are also mostly red and tan.
The Sanshu is a medium sized dog standing at between 50 to 55cm in height and weighing in the region of 20 to 25kg.
There is also a smaller variety. This dog has a wedge-shaped head with a tapering muzzle, dark almond-shaped eyes with small erect ears. The tail is long and is straight but it can bend over the dog’s back. The coat is short and coarse and can come in a number of shades such as tan, white, reddish, white and black.
