The Shikoku Ken
The Shikoku Ken is a medium-sized, primitive hunting dog native to the mountainous Kochi Prefecture on the island of Shikoku — the smallest of Japan's four main islands. Developed over centuries by the Matagi (traditional hunters), the Shikoku was bred to track and hold wild boar in steep, densely forested mountain terrain.
Designated a Living Natural Monument of Japan in 1937, the breed numbers fewer than 8,000 worldwide. They are one of six native Japanese breeds (Nihon Ken) recognized by NIPPO, sitting between the smaller Shiba Inu and the larger Akita Inu in size.
The breed standard calls for a dog of balanced proportions, well-developed musculature, and clean lines — athletic without being heavy, elegant without being fragile. Males stand 49-55cm at the shoulder; females 46-52cm. Their double coat comes in sesame (goma), red sesame (aka-goma), and black sesame (kuro-goma) varieties.
Spirited Bravery
Kan'i is the bold, spirited courage that defines the Shikoku's character. It is not aggression — it is the quiet confidence of a dog that does not back down when it matters. In the mountains, this meant holding ground against boar. In modern life, it manifests as an unflappable presence and an alertness that misses nothing.
Faithful Loyalty
Ryousei is the good-natured loyalty that balances the Shikoku's fire. These dogs form deep, singular bonds with their people. They are not effusive — they will not overwhelm you with affection. But they are always present, always watchful, always yours. Their loyalty is earned, not given, and all the more valuable for it.
Honest Simplicity
Soboku is the quality of being natural and unaffected — a dog without artifice. The Shikoku should look like what it is: a working dog shaped by mountains and centuries of purpose. No exaggeration, no refinement for its own sake. Soboku is the virtue that keeps the breed honest.
Honest expectations
The Shikoku Ken is not a dog for everyone, and we believe saying so clearly is a form of respect — both for potential owners and for the breed itself.
They are intelligent, athletic, and independent. They will test boundaries. They have prey drive. They can be selective with other dogs. They require consistent, patient handling from someone who understands that compliance is earned through relationship, not demanded through force.
A well-raised Shikoku is one of the most rewarding companions you will ever know. But “well-raised” is the operative phrase.
In the right home — with secure fencing, regular exercise, mental stimulation, and an owner who respects their nature — a Shikoku is a deeply loyal, endlessly interesting companion. They are quiet in the house, athletic on the trail, and surprisingly gentle with the people they trust.
We are always happy to discuss whether a Shikoku might be right for your situation. We would rather talk honestly and determine it is not a fit than place a dog in a home that is not prepared.
