Short History

Short History of the Kai Ken

The Kai Ken originated with several other variations of his type: the Shika Inu, meaning “medium-sized dog”. Shika Inus contain several breeds of Japanese dogs, including the Kai, Kishu, and Shikoku. Other breeds similar to the Kai are the Ainu and Shiba Inu, from which this breed could have descended or been an ancestor. The Kai Ken was originally used as a wild boar or deer hunter’s assistant, called a matagi, in the province of Kai, on the island of Honshu in Japan. Matagi greatly appreciated their hunting dogs, and would speak highly of their courage and spirit. It was said that one of these Shika Inus “would not concede a step before danger.” They were once used as fisherman’s helpers, hunter’s aides, and as watch and herding dogs. All of the breeds in this category, however, have been used more often as households pets these days. In the beginning of the Kai’s days, they were thought to be too rough for a household pet, being more wild than his cousins. But the Kai has been bred down to have a more comfortable temperament, although they are still the least responsive of all the Shika Inus. Kai Kens are thought to have existed since medieval times in the Yamanashi Prefecture mountains. The breed stayed pure because of isolation over the years. In 1934, the Kai Ken was designated a National Monument, thanks in part to a breeder named Mr. Haruo Isogai. Mr. Isogai is also classified and categorized all of the Japanese breeds in the 1930s, and helped distinguish the Kai Ken from the other Shika Inus. In 1934 the breed was recognized by the Japanese Kennel Club. Some Kai Kens were imported into the U.S. in the 1950s, and spread from there. Still rare today, the Kai Ken is considered a “national treasure” in Japan.

Caring for Your Kai Ken

Health

General Health

The Kai Ken is not known to be prone to the usual congenital and hereditary problems other canines have. Though the breed appears to be a hardy lot, owners must still be diligent and watch out for signs of PRA, and Canine Hip Dysplasia.

Grooming & Bathing

Grooming & Bathing

They should be brushed weekly to keep their fur mat free and clean. Bathe them as necessary, depending on how dirty they are. Their ears should be checked routinely for wax build up, infection or dirt. Their nails should also be trimmed regularly. Kai Kens shed once or twice a year, making grooming at these times needed. Kai Kens should be trained from puppyhood, as they are very willful.

Exercise & Training

Exercise & Training

Kai Kens need regular exercise on a leash, taking walks or runs. They can also be given a job to do such as herding to satisfy their exercise.
