This breed originated in the ancient Japanese province of Tosa, now called Kochi, as a fighting breed. In Japan, dog fighting has a long history dating back to the 14th century and is considered part of the “culture” of certain provinces.
To develop the Tosa Inu breed, various crossings were made between the Japanese Shikoku-ken dog and six western breeds: English Bulldog, English Mastiff, Pointer, Great Dane, Saint Bernard and Bullterrier. Today, it is believed that the Tosa Inu continues to be used as a fighting dog in some prefectures of Japan clandestinely, but it is also used as a guard dog.
