Due to the popularity of wagyu/kobe beef in United States and Europe, its make people try to duplicate the beef. They crossbred the domestically-raised wagyu with Angus cattle. They also apply some of Kobe traditiosn, like fed their cattle with beer and massaged with sake. However, there's still differences between the original Kobe beef and "Kobe style" beef.
