The Prime Rib primal cut is where we find the most tender, flavorful and desirable steaks in a steer/cow. In layman's words, the Prime Rib is where the flavor is at. The Prime Rib is the undisputed KING of large cuts of beef.

Miyazakigyu Wagyu is the #1 Wagyu brand in Japan and supply stateside is quite limited. These steaks are usually sold for $35-$50 per oz at top steakhouses.

About Japanese A5 Wagyu

A5 Miyazaki beef is measured on five factors:

2. Marbling

4. Meat color and brightness

6. Firmness

8. Texture of meat

10. Color, luster and quality of fat

In the quality grade, the lowest score from the four items of the yield grade is adopted. In other words, even if grade 5 was given to marbling, color and brightness, and firmness and texture, and only fat assessments was grade 4, the quality grade of this beef is classified as grade 4. Quality grading is severely done.

A5 means this beef excels in every single factor. It has a gorgeous webbing of fat that will make you feel like creamy butter in each bite. It's literally like tasting a cloud; a cloud of beef.

Like all of our steaks, they come vacuum sealed and have been hand-cut by our expert butchers.

The Miyazaki-Gyu Difference

At Meat N' Bone we made the conscious decision of selling not only Miyazaki A5 wagyu beef but Miyazaki Gyu because it is the best in the world. Other Wagyu from the area that do not meet the criteria for Miyazakigyu must be sold as "Miyazaki Kensan Gyu" or "Beef from Miyazaki Prefecture." 

All Miyazakigyu is Wagyu but not all Wagyu is Miyazakigyu. Miyazakigyu is one step above Miyazaki Wagyu and is the cream of the crop of all Wagyu from Miyazaki. It is quite literally the best beef in the world.

Every five years, national “Wagyu Olympics” are held to determine Japan’s, and therefore the world’s, best Wagyu. Miyazaki-Gyu is the only Wagyu Program to win this award twice in a row (2007 and 2012) and then be a runner up in 2017.

You can and will find cheaper A5 beef. In fact, even Kobe beef is cheaper. But we chose to offer the best miyazaki wagyu beef in the world at the most affordable price that we could.
