Wagyu simply means "Japanese style beef " in the Japanese language, but it also points to the main four breeds of Japanese cattle, that are prized for their exceptionally well-marbled meat. Miyazaki Prefecture is the 2nd largest producer of Kuroge Wagyu (Japanese Black Cattle), and only the highest quality cattle from this region can be dubbed "Miyazakigyu".
Brisket is the lower chest portion of the cattle that is rather tough comparing to its adjacent muscles but delivers more umami and exceptionally sweet-beefy flavors that lingers on the palate.
For convenience, a portion of the thick-layered fat has been trimmed off however, as Miyazaki beef fat contains significantly higher levels of healthier unsaturated fatty acids called oleic acid, this cut is especially good for slow cooking. Slice into small slivers for yakiniku, slow smoke for pastrami, or slowly braise the brisket at a low temperature for wonderfully flavorful and tender meat.
