The term "two major native cow breed conservation areas" means that, due to the development of its ranching industry, Japan crossbred local cow breeds with breeding bulls from around the world to cultivate new breeds. This led to a sharp decrease in the number of pure native Japanese cows, leaving only these two places that still have pure breeds.
Not only that, world-famous Japanese beef is divided into several brands within the country, and the place where Yan Fei currently is happens to be one of them. It's not just one of several brands; there's another situation where at least two of Japan's well-known beef brands rely on this piece of land beneath Yan Fei to supply their calves.
