Short answer: Japanese Wagyu is identifiable at the individual animal level. Japan operates an official system for cattle and beef in which each animal is given a unique individual identification number, and the identification information can be retrieved through distribution where it applies. As a buyer, you verify by checking the origin and identification details against the records for the specific lot, and by asking for the import documentation — not by judging the marbling by eye, and not by relying on a logo alone.
This guide is for restaurant, hotel and food-service buyers who are purchasing Japanese Wagyu at wholesale and need a practical way to confirm what they are being sold. It covers the documents and identifiers worth asking for, and the things that cannot be verified from a photograph.
1. Japanese Wagyu is individually identified
Japan operates an official traceability system for cattle and beef. Under it, cattle raised domestically in Japan are in principle assigned a 10-digit individual identification number, and that identification information is displayed, transmitted and recorded through the distribution chain, so the animal's production history can be looked up from the number shown on the beef.
Two things follow from that, and both matter when you are buying. First, the system applies to cattle rather than to any product that carries the word Wagyu. Second, the check is only as good as the number's traceability back to the lot in front of you.
The practical consequence for a buyer is that Japanese beef is not sold as an anonymous commodity: where the system applies, a lot can be matched to an identified animal and a production record. Origin and grade can therefore be checked against a record rather than taken on trust — but only when the supplier can actually produce that record for the lot in front of you.
2. What "origin" should mean in a quotation
Japanese Wagyu is not a single product from a single place. The prefecture of production is part of the specification and one of the variables behind price. Miyazaki and Kagoshima are the two origins KHL currently handles.
When a quotation states an origin, it should refer to where the cattle were raised or produced — not the port of export and not the country of the importer. If the origin is not stated, ask for it before comparing prices, and check it against the lot's records rather than a label alone; without that, two quotations are not directly comparable.
3. Documents a trade buyer can reasonably request
Wholesale buyers do not need to audit a supply chain personally. They need the documents that travel with the lot. A reasonable request set looks like this:
| What to ask for | What it tells you |
|---|---|
| Stated prefecture of origin | Which production region the lot came from, and whether it matches what was quoted. |
| Individual identification number | The animal-level identifier behind the lot, where the supplier has it on file. |
| Grade | The Japanese grading result for the carcase (A5, A4 and so on), as quoted. |
| Import documentation, where applicable | Whatever import documentation accompanies the lot, so the entry of the goods can be checked. |
| Cut and pack specification | The cut and format you are actually receiving, which is what your yield calculation depends on. |
What a supplier can produce varies by product line, by pack format, by how the lot was purchased and by what documentation travelled with it. Ask which of these are available for the specific line you are buying rather than assuming they all are — a supplier who answers "let me check that lot" is giving you a more useful answer than one who answers "yes" to everything.
4. What you cannot verify from a photograph
Marbling is visible. Almost nothing else is. A photograph of a well-marbled steak cannot tell you the prefecture, the individual animal, the grading result or the country of import. Those come from records, not images.
This matters commercially because a lot of Wagyu marketing is visual. A buyer comparing a photograph against a spec sheet is not comparing the same kind of evidence. If the specification cannot be backed by a document, treat the origin and grade as unconfirmed.
5. Why this matters to a restaurant, not just to a supplier
Once a Wagyu origin or grade appears on your menu, it becomes a claim your business makes. If the claim cannot be traced back to the lot, the exposure sits with the restaurant at the point of sale, not only with the supplier.
Keeping the origin and grade on file for each delivery also makes menu changes easier. When the next shipment carries a different prefecture or cut, you can update the menu description against a record instead of against memory.
6. Eight questions worth asking your supplier
- Which prefecture is this lot from?
- Is the individual identification number available for this line?
- What grade is recorded for this carcase, and is that consistent with the specification?
- What import documentation can you provide for this lot?
- Which cuts and pack formats are on this shipment?
- Is this the same specification as my previous order, or has the origin or cut changed?
- How has the product been stored and transported since import?
- What is the lead time if I confirm this specification today?
None of these are adversarial questions. A supplier with a documented chain answers them from records, and the answers tell you how much of the supply chain they actually hold.
7. A note on certification claims
Origin documentation and product certification are not the same thing. A statement about Japanese origin, grade or traceability does not automatically describe a Wagyu-specific certification, and a supplier's own food-safety certification is a separate matter from the authenticity of a particular lot. Keep the two questions separate when you assess a supplier: can this lot be traced? and is this supplier certified to handle food safely?
KHL's own certification and cold chain information is documented on the certifications and supply capability page.

Sources / Further verification
The traceability framework described above is a Japanese government system, not a KHL system. To check it at source:
- What the number is and what it lets you check — MAFF, 「パック詰めの牛肉に書いてある個体識別番号とは何ですか」: beef from cattle raised in Japan carries a 10-digit individual identification number, and the number lets you check when and where the animal was born, raised and processed
- How the system is administered — National Livestock Breeding Center (NLBC), 牛の個体識別業務について: a national, uniform individual identification number is assigned and the birth, movement and slaughter information is managed centrally
- Where a number can be looked up — NLBC, 牛の個体識別情報検索サービス: the public search service, which asks for the 10-digit individual identification number
These are general references for how Japanese beef is identified and recorded. They are not warranties about a specific lot, and they do not tell you what any particular supplier can produce. For that, ask the supplier about the lot you are buying.
