This low back of Japanese Wagyu A5 is identified in the catalog with Kagoshima and a weight of approximately 3.1 to 3.3 kg. It gathers the low back cut with a commercial graduation of high fat infiltration. It can be divided into parts for different services, paying attention to the conservation and performance of a large format.
The Kagoshima reference distinguishes this piece from other Japanese loins advertised as A5. By its size, it makes sense to calculate the entrecots you want to obtain before purchasing and compare the format with the cut rations of the same catalog.
