A4 Wagyu Explained: What the Grade Does and Does Not Mean
A4 Wagyu combines yield grade A with quality grade 4. It does not mean “cheap A5”, nor does it predict one exact flavour or retail price. To decide whether an A4 offer suits you, read its cut, stated marbling and portion alongside the grade.
This is an educational guide. No active Japanese A4 product was listed in Beleaev's range checked on 28 August 2026. The photograph and card show a separately labelled Japanese A5 ribeye, not A4.
Key takeaways
- A4 contains both a yield letter and a quality number.
- The final quality grade follows the lowest assessed component.
- A4 does not always mean BMS 5–7.
- Value depends on the actual offer and meal, not the grade alone.
What does the 4 in A4 mean?
Japanese quality grading considers marbling, meat colour, firmness and texture, and fat characteristics. The lowest assessed component determines the final number. MAFF's grading overview explains this structure, which is separate from the yield letter.
The result is useful specification, but it is not a verdict that you will enjoy every A5 steak more than every A4 steak. Personal preference still involves the cut, preparation and how much richness you want in a meal.
Is A4 always BMS 5–7?
No. In the JMGA standard, BMS 5–7 corresponds to marbling-component grade 4. But another component can limit the overall grade to 4 even when marbling scores more highly. Treating A4 as an exact BMS range misses that distinction.
Ask for the product's stated BMS if that detail matters to your purchase. If it is not supplied, don't estimate it from the title or a photograph. The A5 and BMS guide explains the same boundary for A5 products.
When might an A4 offer make sense?
It can make sense when the documented product fits the cut, portion and budget you want. The important word is “product”. An A4 fillet and an A5 ribeye are not a controlled comparison of grade; they change the cut at the same time.
| Your priority | Useful comparison |
|---|---|
| A particular steak texture | Start with the same cut |
| A measured tasting course | Compare selected raw weights |
| A spending limit | Compare the total order, including delivery |
| A particular marbling level | Use the stated score, not an assumed one |
A4 is not automatically cheaper. Cut, pack size and the rest of the specification can change the total price. Our retail price comparison guide shows how to compare the selected weight fairly.
Should you cook A4 for longer than A5?
There is no universal extra cooking time attached to A4. Thickness, starting temperature, equipment and the required safe preparation matter more than the grade number. Follow the actual product instructions and choose a method suitable for that cut.
If you are comparing grades at home, match the cut and format first. Otherwise a difference caused by thickness or cooking could easily be mistaken for a grade difference.
A separately labelled A5 option
If you want Japanese A5 rather than waiting for a specific A4 offer, the Japanese A5 Wagyu Ribeye, 200g, is a current Kagoshima option. It is frozen and its listing calls for refrigerator thawing, cooking from chilled and no refreezing after complete thawing.
Use the A5 ribeye cooking guide for this item. Choosing it does not turn it into the A4 product discussed above.
Frequently asked questions
Is A4 a failed grade?
No. It is a defined result within the Japanese grading system, not a label for defective beef.
Does A4 guarantee less richness?
No single overall grade predicts your experience of every cut. Read the actual marbling information and consider the portion and preparation.
Can I order A4 using this card?
No. The card is clearly labelled Japanese A5 ribeye. Check the current collection for what is actually offered.
