Wagyu Authenticity

How Authentic Wagyu is Verified

Learn how authentic Japanese Wagyu is verified and how J-GYU ensures every shipment meets these standards.

The Marks of Authencity

Every J-GYU shipment is backed by official documentation issued in Japan. These three identifiers work together to verify that every product is genuine, traceable, and officially graded:

UNIVERSAL WAGYU MARK

Confirms the animal was born, raised, and processed in Japan

JMGA GRADE

Official quality grade from Japan's sole grading authority

Individual Identification No.

Traces this cut back to a single animal in Japan's national registry

THE UNIVERSAL WAGYU MARK

Introduced in 2007, the Universal Wagyu Mark serves as a globally recognized symbol of authentic Japanese Wagyu. Products displaying the Universal Wagyu Mark have been verified through Japan’s official traceability system, confirming the animal was born, raised, and processed in Japan.

Authenticity Mark No. 2

THE JMGA GRADE

The Japan Meat Grading Association (JMGA) is the official authority responsible for grading beef in Japan.

Every carcass is assessed for yield grade (A–C) for usable meat ratio, and quality grade (1–5) for marbling, color, firmness, and fat quality.

J-GYU carefully sources Wagyu across the A-grade range, selecting the appropriate grade for each culinary application — from premium steaks to yakiniku and specialty cuts. Every carcass, regardless of grade, is officially graded and certified by the JMGA.

AUTHENTICITY MARK NO. 3

THE INDIVIDUAL IDENTIFICATION NO.

Every certified Japanese Wagyu carcass is assigned a unique identification number linked to Japan’s national cattle registry. This allows every animal’s history to be verified — from birthplace and breed to ownership records and processing.

WHY IT MATTERS

WHAT YOU'RE ACTUALLY PAYING FOR

Authenticity Protects Your Purchase

Authentic Japanese Wagyu commands a premium because every claim is backed by verifiable proof — not marketing.

Grade Defines Quality

Marbling, yield, firmness, color, and fat quality are independently assessed using Japan’s official grading standards.

Traceability Builds Trust

Every certified shipment can be traced back to its origin, giving you complete confidence in what you’re buying.
