An excerpt from the article 15 facts about Wagyū beef

The Japanese government has declared Wagyu a national treasure. Prior to the legislation, some 225 specimens were exported between 1976 and 1997, and today they form the basis of Wagyū cattle breeding outside Japan.

However, most of these animals are not full-blooded Wagyūs, but crossbred Wagyūs with Angus cattle.
