Japanese A5 Wagyu (わぎゅう, Wagyu) serves as the luxury benchmark in global premium dining — from Kobe beef, Matsusaka beef to Ohmi beef and Miyazaki beef, every Wagyu undergoes rigorous documentation including bloodline registration, feeding logs, and slaughter grading. For Macau's teppanyaki establishments, yakiniku specialty shops, Michelin-starred Japanese restaurants, and five-star hotel executive kitchens, the stable supply of Japanese A5 Wagyu represents the core competitive advantage for menu signature items. From Inari Global Food's B2B supply perspective, this article breaks down the four key dimensions of Japanese A5 Wagyu procurement — grading / origin / cut / cold chain — and compares the publicly available coverage differences against competitors (Global Seafood / Eat First).
1. Japanese Wagyu Grading System: How to Read A5 / A4 / A3?
The grading system of JMGA (Japan Meat Grading Association) is the globally recognized quality standard for Wagyu beef. Each Wagyu carcass is personally assessed by a certified grader after slaughter, with the grade consisting of two dimensions:
- Yield Grade: A / B / C - Grade A represents the highest edible yield (approximately 72%+), B is 69-72%, and C is <69%.
- Quality Grade: 1-5 - Determined by 4 sub-items: BMS (Beef Marbling Standard, 1-12 points), BCS (Beef Color Standard), BFS (Beef Fat Standard), and Texture / Firmness. Each sub-item is scored based on the lowest rating.
Reference Table:
| Grade | BMS Range | Typical Usage |
|---|---|---|
| A5 (BMS 8-12) | 密集霜降，雪花紋細膩均勻 | Michelin Teppanyaki, Premium Yakiniku, Omakase Main Course |
| A4 (BMS 5-7) | 霜降明顯，仍見肉紅紋 | High-end Yakiniku, Hotel Fine Dining, Set Menu Main Course |
| A3 (BMS 3-4) | 霜降較少，瘦肉感重 | Standard Commercial Restaurants, Teishoku, Yakiniku Side Dish |
Yinhe Macau B2B procurement focuses primarily on A5 (BMS 8-12), with A4 as secondary. A3 is generally not included in the procurement list, as the Macau high-end food and beverage market considers A5/A4 as the mainstream.
2. Four Major Japanese Wagyu Production Areas (Based on Inari Supply Chain)
Based on public data from Japan's Ministry of Agriculture, Forestry and Fisheries (MAFF) and livestock associations in each region, Wagyu production areas are registered as "Brand Beef" (local brand beef). Inari currently covers the following four major production areas for B2B procurement:
- Hyogo Prefecture — Kobe Beef: A premium brand with Tajima cattle bloodline, recognized globally as the most prestigious. Only Tajima cattle raised in Hyogo Prefecture meeting strict A4/A5 and BMS ≥ 6 standards can be labeled as Kobe
