Okay, no problem. Regarding the Japanese Wagyu pedigree tracking system, it essentially means giving each cow a unique "ID card" and "electronic pedigree" that follows it from birth to the table. Let me break it down for you so it's crystal clear.

Revealed! The "ID Card" and "Pedigree" System of Japanese Wagyu

Hey, when talking about Japanese Wagyu, besides its melt-in-your-mouth texture, you might also wonder: how can I be sure this incredibly expensive meat is the real deal? What if some "imposter cow" is trying to pass itself off?

Don't worry, the Japanese are incredibly meticulous about this. They've established an extremely strict pedigree registration and traceability system. Simply put, every authentic Wagyu cow has its entire life meticulously documented.

1. 🐮 Registered at Birth: A Unique "ID Number"

This process starts the moment a calf is born.

  • Ear Tagging: Within days of birth, the farmer must attach a unique 10-digit ear tag (Individual Identification Number) to the calf. This tag stays with it for life, just like our personal ID numbers – unique nationwide, never duplicated.
  • Registration: This 10-digit number isn't arbitrary. It's immediately entered into a national central database managed by the Livestock Improvement Center. Simultaneously, the farmer submits an application to the National Wagyu Registration Association to register the calf's pedigree.

2. 📜 Building the "Electronic Pedigree": Tracing Back Generations

An ID number alone isn't enough; a "pedigree" (Pedigree Certificate) is also essential.

In the database, alongside the cow's own 10-digit ID, the following key information is recorded:

  • Parent Information: Who its mother is (also with a 10-digit ID), and who its father is (typically recorded as the ID of the bull that provided the semen).
  • Grandparent Information: Following the parents' IDs, you can trace back further, easily finding its grandparents and even great-grandparents. This creates a clear "family tree."
  • Basic Information: Date of birth, sex, breed (e.g., Japanese Black), and place of birth (which farm in which prefecture).

This "electronic pedigree" is crucial. It proves the cow comes from a "distinguished lineage," possessing pure bloodlines, rather than being of unknown or dubious origin.

3. 🚚 Tracking the "Life Journey": From Farm to Slaughterhouse

Throughout its life, wherever this cow goes, its "ID number" follows it, and the information is constantly updated in the central database.

  • Movement Records: For example, if a calf is born on Farm A, then sold to Farm B for fattening, this move is fully recorded. The database clearly shows when it moved, from where, and to where.
  • Feeding Records: What feed it ate at each farm, whether it got sick, what medications were used – all this information is also documented.

This ensures transparency and traceability at every stage: from birth, through rearing and fattening, right up to the slaughterhouse.

4. 🍽️ From Plate to Source: Consumers Can Trace Too!

The most impressive part of this system is that it bridges the final gap, allowing consumers to participate.

When you visit a high-end Japanese butcher shop or restaurant serving Wagyu, you'll often see the "Individual Identification Number" (that 10-digit ID) displayed next to a cut of beef.

At this point, you can take out your phone, go to the Livestock Improvement Center's official traceability website, and enter those 10 digits.

"Ding" – magic happens!

The website instantly displays the cow's complete "life history":

  • Its date of birth
  • Its sex and breed
  • Its "pedigree," including the names and IDs of its parents and grandparents
  • The addresses and names of all the farms it lived on from calfhood
  • The date it was processed and at which slaughterhouse

This means you can clearly trace exactly which cow the meat on your plate came from, what its "bovine life" was like, and whether its "family" was distinguished.

To summarize, why is this system so impressive?

  • For Consumers:

    1. Guarantees Authenticity: You can be absolutely sure that what you paid top dollar for is genuine, pedigree Wagyu – no tricks.
    2. Ensures Food Safety: If a food safety issue arises, the source (which farm, which cow) can be traced instantly, allowing for rapid containment.

  • For Producers:

    1. Scientific Breeding: Clear "pedigrees" allow for selecting the best genetics for breeding, continuously improving Wagyu quality.
    2. Protects Brand Value: It's this incredibly strict system that underpins the reputation and premium price of the "Japanese Wagyu" brand.

So, the reason Japanese Wagyu is world-famous isn't just its taste. It's also this astonishingly transparent pedigree tracking and management system behind it. Every bite you take comes with peace of mind and trust.
