Akaushi Grass-fed cattle

Akaushi is a separate and distinct Breed from the other Japanese cattle. There are no similarities, genetically or phenotypically, between Akaushi and the other Japanese Breeds. Based on my research the Akaushi Breed started with the South Korean breed known as Hanwoo. In ~1870 Devon was infused into the Hanwoo cattle and in ~1910 Simmental was incorporated into the breed. Around 1910 the breed was closed to any other outside genetics and the Akaushi breed was formed, and to this day remains the same, a closed herd for well over 100 years.

Mitsuru Minezawa:
    “The word Wagyu is an anglicisation of the Japanese-language “wa-gyu”, which simply means our (Japanese produced) beef cattle. It does not describe any single breed.”
