Wagyu is the category of a number of Japanese breeds of beef cattle. Wagyu beef is known to have fine marbling, which means that the meat contains intramuscular unsaturated fat that produces a pattern similar to marble. Famous examples of Wagyu beef include Kobe, Matsusaka and Ōmi beef.
The name Wagyu literally translates to "Japanese beef", where wa means "Japanese" and gyū means "beef".
Wagyu beef is appreciated around the world, but unfortunately, because of this, it is often mispronounced by English speakers. In the United States, Wagyu is often pronounced as wa-goo, but this is incorrect. The correct pronunciation of Wagyu is Wah-gyuu. So, the "y" in Wagyu is pronounced exactly how you pronounce the letter "u" and this "u" sound must be extended in length, as you can hear in the audio pronunciation.
