Originally used for hunting large game, the breed fell out of favor with the Japanese people once European breeds started being imported into the country after WWI. In the 1930s, breeder Haruo Isogai worked to improve the reputation of the Kai Dog, earning the breed a designation as a "Natural Monument.""
