Buying authentic A5 wagyu beef can feel overwhelming. Between confusing grading systems, misleading labels, and wildly varying price points, it's easy to make expensive mistakes. This guide cuts through the noise so you can buy A5 wagyu with confidence—whether you're shopping online or at a specialty butcher.
What Does "A5" Actually Mean?
Japan's beef grading system is the most rigorous in the world. The letter (A, B, or C) rates yield—how much usable meat comes from the carcass. The number (1 through 5) rates quality, based on four criteria: marbling, meat color, fat color, and firmness. A5 is the absolute pinnacle: maximum yield, maximum quality.
Within A5, the Beef Marbling Score (BMS) ranges from 8 to 12. A BMS 8 is the entry point for A5 status, while BMS 12 represents the most intensely marbled beef on earth. When shopping, look for the BMS number—it tells you far more than the A5 label alone.
Authentic vs. Fake: How to Spot Real A5 Wagyu
The term "wagyu" isn't legally protected in the United States, which means you'll encounter plenty of misleading labels. Here's how to verify authenticity:
- Certificate of authenticity: Every genuine Japanese A5 wagyu cut should come with a certificate traceable to the individual animal, including a 10-digit nose print ID
- Prefecture of origin: Authentic A5 comes from specific Japanese prefectures—Miyazaki, Kagoshima, Hyogo (Kobe), Hokkaido, and others
- USDA import verification: Only a handful of Japanese producers are approved to export to the U.S. If the price seems too good, it probably isn't genuine
- Marbling appearance: Real A5 wagyu has fine, web-like intramuscular fat distributed evenly throughout—not thick white streaks
Best Cuts for First-Time Buyers
If you've never purchased A5 wagyu before, start with these cuts:
Ribeye (Ribeye Cap / Riburosu)
The ribeye is the most popular A5 cut for good reason. Its generous marbling makes it forgiving to cook, and the flavor profile hits every note—buttery, umami-rich, with a clean finish. Expect to pay $120–$180 per pound for genuine A5 ribeye.
Striploin (Sāroinu)
Slightly firmer than ribeye with a more concentrated beefy flavor. The striploin offers an ideal balance of marbling and texture. It's a great choice if you find ribeye too rich. Typical pricing runs $100–$160 per pound.
Filet / Tenderloin (Hire)
The most tender cut, though with less marbling than ribeye or strip. A5 filet is perfect for those who want the wagyu experience without the intensity of fat-heavy cuts. This is the priciest cut, often $150–$220 per pound.
Zabuton (Chuck Flap)
An underrated cut that delivers exceptional marbling at a lower price point—often $80–$120 per pound. The zabuton is a rectangle of pure, evenly marbled beef that's ideal for yakiniku-style grilling.
How Much A5 Wagyu to Buy Per Person
This is where most first-time buyers go wrong. A5 wagyu is extraordinarily rich—you need far less than you'd buy for a conventional steak dinner.
- As a main course: 3–4 ounces per person (yes, really)
- As an appetizer or shared experience: 1–2 ounces per person
- For a tasting with multiple cuts: 2–3 ounces total per person across all cuts
A single pound of A5 wagyu comfortably serves 4–6 people as a main, or 8–10 as part of a multi-course meal. Buying too much is the most common—and most expensive—beginner mistake.

A5 Wagyu Price Guide: What to Expect in 2026
Pricing for genuine A5 wagyu varies by cut, BMS score, and prefecture:
- Ground wagyu / trim: $30–$50/lb (great for burgers and bolognese)
- Zabuton / chuck cuts: $80–$120/lb
- Striploin: $100–$160/lb
- Ribeye: $120–$180/lb
- Tenderloin: $150–$220/lb
- Kobe-certified A5: 20–40% premium over equivalent non-Kobe A5
If you see "A5 wagyu" priced significantly below these ranges, investigate carefully. It may be crossbred wagyu (which can be excellent but isn't Japanese A5) or mislabeled product.
Storage and Handling Tips
Once your A5 wagyu arrives:
- Keep frozen until 24–48 hours before cooking, then thaw slowly in the refrigerator
- Never microwave-thaw—the delicate fat structure will suffer
- Frozen shelf life: 6–12 months when vacuum-sealed and kept at 0°F or below
- Once thawed: Cook within 2–3 days for best results
- Slice thin before cooking: A5 wagyu is best enjoyed in thin slices (¼ to ½ inch) cooked quickly at high heat, not as a thick American-style steak
Red Flags When Buying A5 Wagyu
Walk away if you encounter any of these:
- No certificate of authenticity or traceability information
- Vague origin claims like "Japanese-style" or "wagyu-grade"
- Prices dramatically below market rates
- Thick, uneven fat striping instead of fine web-like marbling
- Sellers who can't name the specific prefecture or farm
- Products labeled "American A5" or "Australian A5"—neither country uses Japan's grading system
