Wagyu beef, or Japanese beef, is widely regarded as one of the finest and most expensive types of beef in the world. It comes from four specific breeds of Japanese cattle: Japanese Black, Japanese Brown, Japanese Polled, and Japanese Shorthorn. These cattle are raised under strict conditions, including a diet of high-quality feed, limited exercise, and regular massages. As a result, Wagyu beef is exceptionally tender, well-marbled, and flavorful. It can be enjoyed in various ways, including as steaks, roasts, and shabu-shabu.
