What Do A5, A4, and A3 Wagyu Mean?

If you’ve ever shopped for Wagyu and noticed labels like A5, A4, or A3, you might have wondered — what do those letters and numbers really mean? These grades aren’t just marketing; they tell a detailed story about the beef’s quality, marbling, and even how it feels when it melts in your mouth. Let’s break it down simply.

How Wagyu Beef Is Graded in Japan

Wagyu beef is graded by the Japan Meat Grading Association (JMGA) — one of the most precise systems in the world.
Each cut is scored on two parts:

1. Yield Grade (the letter: A, B, or C)

   • A = High yield (more edible meat per cow)

   • B = Average yield

   • C = Lower yield

   Most premium Wagyu is graded A, meaning you get the most meat and the least waste.

2. Quality Grade (the number: 1–5)

   • Based on marbling, meat color, texture, and fat quality

   • 5 = Exceptional quality

   • 1 = Lowest quality

Combine the two and you get the full grade — for example, A5 Wagyu, which means the highest yield and the highest quality.

Understanding the Differences Between A3, A4, and A5 Wagyu

A3 Wagyu – Mild and Balanced

A3 offers good marbling and a pleasant bite without being overly rich. It’s a great entry point for those trying authentic Wagyu for the first time.

Best for: everyday grilling or adding to rice bowls for a flavorful, balanced meal.

A4 Wagyu – Rich Yet Refined

A4 finds the perfect middle ground — buttery texture, deep umami, and just enough fat to coat your palate without feeling heavy.

Best for: home chefs who want luxury flavor that’s still easy to cook and share.

A5 Wagyu – The Highest Grade

This is the gold standard. The intricate marbling in A5 Wagyu melts into the meat, creating a texture so tender it almost dissolves on your tongue. Each bite is pure, rich umami — the ultimate expression of Japanese craftsmanship.

Best for: celebrations, gifts, or when you want to taste perfection.
