Shamo (่ป้ถ) is an overall designation for game fowl in Japan. There are seven recognised breeds of Shamo chicken in Japan, all of which are designated Natural Monuments of Japan. The Shamo breeds are thought to derive from fighting chickens of Malay type brought from Thailand in the early part of the seventeenth century.[1]:โ13โ

History
editThe Shamo breeds are thought to derive from fighting chickens of Malay type brought from Thailand in the early part of the seventeenth century or early Edo period (1603โ1867).[1]:โ13โ[2]:โ270โ The Japanese word Shamo derives from Siam, the former name of Thailand.[2]:โ270โ The birds have been selectively bred for several hundred years for their fighting ability. Some were imported to Western countries in the 1970s;[3]:โ288โ in the twenty-first century, the birds are reported from four countries outside Japan: Australia, Ireland, the United Kingdom and the United States.[4]
Breeds
editThe seven recognised Shamo breeds designated as Natural Monuments of Japan are:[1]:โ13โ[5]:โ92โ
- Ehigo-Nankin-Shamo, a slightly taller and more slender variant of the Nankin-Shamo from Niigata[3]:โ214โ
- O-Shamo ("large Shamo", ๅคง่ป้ถ)

Other Shamo variants are the Chu-Shamo ("medium Shamo", ไธญ่ป้ถ)[2]:โ321โ and the Chibi Shamo, the bantam of the Yamato Gunkei.[2]:โ322โ
In the West
editIn Western countries, the breed name Shamo includes both the O-Shamo and the Chu-Shamo.[2]:โ270โ In the United Kingdom, different weight ranges are given in the British Poultry Standards for the two types within the Shamo breed;[3]:โ289โ the Ko-Shamo, Nankin Shamo, Yakido and Yamato Gunkei are recognised as distinct breeds.[6] The Entente Europรฉenne recognises the Shamo, Ko-Shamo, Yakido and Yamato Gunkei, and lists the Chu-Shamo and Nankin Shamo as unrecognised.[7] The Australian Poultry Standards list only one form of Shamo, which has a minimum weight of 3ย kg.[8]:โ227โ The American Poultry Association recognises the Shamo as a breed, both full-sized and bantam.[9]
