Where are Tosa Inus from?

Tosa Inus, also known as the Japanese Mastiff, are from the Tosa Province of Japan, now part of modern-day Kōchi Prefecture on Shikoku Island. They were first developed in the mid-19th century, around the 1870s. Tosa Inus have a unique background, blending native Shikoku dogs with European breeds like Bulldogs, Mastiffs, and Great Danes to create their distinctive look.
