The Kai Ken (Japanese: 甲斐犬) is a medium-sized dog traditionally used to hunt Kamoshika (Japanese goat-antelope), deer, wild boar, and bear in the Kai mountains of Japan. Due to centuries of isolation in the mountains, the Kai Ken is considered a rare breed even in its own country.
Often referred to as the Tiger Dog, they are fearless and tenacious hunters who will swim after prey or climb a tree to get to them.
The first Kai Ken dogs were brought to the United States in the 1950’s by American service men who had served in Japan.
