Wagyu, explained
What is Kobe beef?
“Kobe” is a tightly controlled regional brand of Japanese Wagyu, defined through Tajima lineage, Hyogo production, carcass criteria, and association certification. Here is the association’s definition and how to evaluate a Kobe claim.
Kobe is a brand of Wagyu, not a breed
Start here, because it is where most confusion begins. Wagyu means Japanese-breed cattle. Kobe is a single, registered brand within Wagyu, the way Champagne is one place within sparkling wine. Every piece of Kobe is Wagyu, while most Wagyu is not Kobe. They answer different questions: one is the broader category and the other is an association-certified regional brand.
What makes beef officially Kobe
Kobe is certified by the Kobe Beef Marketing & Distribution Promotion Association in Japan. To carry the name, a carcass must clear every one of these:
- Breed
Tajima-gyu, a strain of Japanese Black (Kuroge Washu), and nothing else.
- Origin
Born, raised, and slaughtered in Hyogo Prefecture, the region whose capital is Kobe.
- Marbling
A Beef Marbling Standard of BMS 6 or higher on the 12-point scale.
- Grade & weight
Meat quality grade 4 or 5, yield grade A or B, and a gross carcass weight of 499.9 kg or less.
- The animal
A bullock (castrated male) or a heifer that has never calved.
- Proof
Each qualifying carcass is stamped with the Nojigiku chrysanthemum seal and issued a 10-digit traceability ID and a Kobe Beef certificate.
The association’s current FAQ reports roughly 7,500 Tajima cattle going to market annually, of which about 7,000 qualify as Kobe. These are approximate current figures and can change by production year.
Kobe vs Wagyu vs A5
These three words get used as if they compete, but they answer different questions.
In Japan, four recognized breeds and permitted crosses among them; overseas Wagyu programs can also include crosses with other breeds, so the applicable standard matters.
A grade, the top of the Japanese quality-and-yield scale. Many prefectures produce A5, so A5 alone does not mean Kobe.
A brand, Tajima cattle from Hyogo that also clears the production and grading rules above. Kobe has its own association certificate and authorized-store registry; other Japanese brands also use traceability and certification.
So a steak can be genuine A5 Wagyu and still not be Kobe. Kobe is a stricter, narrower claim, which is exactly why it is the one most worth verifying.
How to know it is real
The 10-digit individual identification number links to traceability records, while the association certificate and authorized distribution chain support the Kobe brand claim. WagyuSpot applies a deliberately narrower restaurant badge rule in the U.S.: two things have to be true at once:
- On the registry
The venue appears in the Kobe association’s official directory, not just using the word.
- On the menu
Kobe is on the current menu you can order tonight. A license is permission to serve it, not proof that it is being served.
U.S.-raised beef cannot qualify as official Kobe. “American Kobe” or “domestic Kobe” should not be read as certification. Our directory requires both an official venue-directory match and a current menu claim before it shows a Kobe badge.

Common questions
- Is Kobe beef the same as Wagyu?
- No. Kobe is one specific brand of Japanese Wagyu, not a separate kind of beef. All Kobe is Wagyu, but only a narrow subset of Wagyu qualifies: eligible Tajima cattle must meet the Kobe association's Hyogo production, grade, sex, and carcass criteria.
- What makes beef officially Kobe?
- The certifying association requires Tajima-gyu cattle born, raised, and slaughtered in Hyogo Prefecture; BMS 6 or higher; meat quality grade 4 or 5; yield grade A or B; gross carcass weight of 499.9 kg or less; and a bullock or a heifer that has never calved. Each qualifying carcass is stamped with the Nojigiku chrysanthemum seal and carries a 10-digit ID.
- What is the difference between Kobe and A5 Wagyu?
- A5 is the top yield-and-quality combination on Japan's beef scale; Kobe is a place, lineage, and production brand from Hyogo. Kobe requires quality grade 4 or 5 and yield grade A or B, so qualifying carcasses can be A4, A5, B4, or B5. An A5 steak can be genuine Japanese beef without being Kobe.
- Can you get real Kobe beef in the US?
- Yes, through the Kobe association's authorized chain. WagyuSpot gives a restaurant a Kobe badge only when the venue appears in the official directory and Kobe is on its current menu. A seller may also source through an authorized distributor, so request the certificate and chain for the exact product.
- How can I tell if Kobe beef is real?
- Certified Kobe traces to Hyogo and can be checked through its individual identification number and certificate. For WagyuSpot's restaurant badge, the venue must appear in the official directory and name Kobe on its current menu. Retail sourcing can also run through an authorized distributor, so ask for the evidence tied to the exact product.
