Japanese A5 wagyu thin slices come from Japan’s highest A5 grade black wagyu, with extremely fine marbling, a vivid red colour and white fat distributed like snowflakes throughout the meat. Once cooked, the fat releases a rich buttery aroma and the meat turns exceptionally tender and smooth, giving you a balanced wagyu flavour that feels luxurious without needing much seasoning. Thin slices are best for quick cooking, since the rich marbling works best when the meat is only heated briefly; they are perfect for shabu-shabu, sukiyaki, Korean BBQ, teppanyaki, Japanese-style grilling or as a hot pot topping.

Japan's main grading standards are divided into two categories: "lean meat percentage" and "meat quality grade." These two categories are graded separately, then combined to form the final grade.

Lean meat percentage grading, known in Japan as "Aru-ji," refers to the percentage of edible meat from a cow.

It is divided into Grades A, B, and C.

Grade A: Lean meat percentage reaches 72%, with an extremely high edible ratio.

Grade B: Lean meat percentage is 69% to 72%.

Grade C: Lean meat percentage is below 69%, with a low edible ratio.

Meat quality grading is primarily based on four criteria: "Brownish Mixture System" (BMS) of the ribeye muscle, "muscle composition," "meat color," and "fat color."

The strictness of Japan's grading system lies in this: each individual grading standard has a score from 1 to 5, and the lowest grade is taken as the final meat quality grade.

Combining these two aspects, Japanese Wagyu beef has a total of 15 grades.

For example: A beef with a lean meat percentage of grade A, a BMS (Body Quality Management System) grade of 5, a muscle composition grade of 5, a meat color grade of 5, and a fat color grade of 1, would be graded "A1".

Therefore, the highest grade, "A5", is extremely difficult to achieve. All meat quality grades must be at level 5, and the lean meat percentage must be grade A to be rated "A5".
