Measuring about 30 inches (76cm) tall, the Shamo is the second tallest chicken breed.

The Shamo was first imported to the United States for cockfighting in 1874. It is a protected species in Japan. Shamos have very short, hard feathers that may not fully cover the body.

Shamos are very aggressive fighters. Chicks will begin fighting almost immediately after birth, and cocks must be kept separated, but Shamos like humans and will tame down nicely.
