About the Tosa Inu
The Tosa Inu, also known as the Tosa Ken or Japanese Mastiff, is a rare and powerful breed that originated in the Tosa region of Japan during the late 19th century. It was developed by crossing native Shikoku dogs with Western breeds including Bulldogs, Mastiffs, Great Danes, and Bull Terriers. The Tosa was historically bred for dog fighting in Japan, where matches are conducted with ceremony and ritual. This massive breed features a short, dense coat, a broad head, and a muscular body that can weigh anywhere from 80 to over 200 pounds.
