Kai Ken

Other names: Kai, Tora Inu, Tiger Dog

Kai Ken

This stripy tiger of a Japanese dog is literally a national monument, celebrated and protected as one of the six Japanese breeds known collectively as Nihon Ken. Wedge-shaped in every direction and covered with a layer of fiery brindle, the Kai Ken’s affable expression completes the ‘easy on the eye’ package. Personality-wise, you can expect the same: reserved, yet pleasant, thawing with familiarity to become a warm and loyal colleague, whether that work is the trial of everyday life or hunting deer, boar, and bears in the mountains, her preferred habitat.

Origins and history

The Kai Ken was little known outside of the mountain province of Kai on the main island of Japan until the 1930s when she was discovered, categorised, celebrated, and finally entered into the annals of the Japanese Kennel Club. For this reason, today’s Kai Ken is thought to be among the purest of breeds. They were introduced to America by returning soldiers in the 1950s, but are today rarely seen outside of Japan, the United States, and the realm of the cartoon, in which they frequently appear.

    Whatever it is about the appearance of Japanese dogs that lends them to being illustrated in drawings, this pooch has it in spades. Perhaps it is the economic use and re-use of one key shape across her front end: a wedge-shaped beak, head, eyes, and ears, casually offset by a fluffy Basil Brush tail that curls around to meet her back. Those eyes are certainly part of it too, despite their mysterious darkness. The outer corners turn up with charm, while more to the point her brows are expressive, almost human. Fluffy tiger-dog that she is, with those black and flame stripes, all this teddy-bear adorability comes with a sense of strength and athleticism because she is, after all, a mountain dog.

    Good to know

    It can be very hard to get hold of one of these dogs in the UK and potential families may need to undergo a lengthy import process that isn’t always kind on the dog (think: quarantine).
