Brief historical summary

Japan has a long history of dog fighting, beginning in the 14th century. With such a history in the background, this breed was produced as a hybrid of Shikoku-ken and Western breeds. Named after the area where they were bred, these dogs are sometimes called "Japanese Mastiffs". The Western dogs used for creating the breed were Bulldogs (1872), Mastiffs (1874), German Pointers (1876) and Great Danes (1924), all of which were used to improve the breed by sequential mating. According to some accounts, St.Bernards and Bull Terriers were also involved, but it is not known in what years they were used. The Tosa's established features of stamina and the fighting instinct typically found in Mastiffs may be attributed to the involvement of such breeds.
