FAQ
Is this real Japanese A5?
Yes. It is graded A5 by the Japan Meat Grading Association, and every animal is traceable by a 10 digit ID.
What does BMS mean?
Beef Marbling Standard, Japan's 1 to 12 marbling scale. A5 beef scores 8 to 12, and a higher number means more marbling.
How much per person?
3 to 4 oz, or about 2 oz as one course in a bigger meal.
Is A5 the same as Kobe?
No. A5 is a grade. Kobe is a brand from Hyogo Prefecture. Some Kobe is A5, and most A5 is not Kobe.
What is the best way to cook it?
Small pieces seared hot and fast in cast iron. See How to cook above.
How is it shipped?
Frozen and vacuum sealed in an insulated cooler with ice, shipped from St. Louis by 2-day air. Shipping is free on orders of $199 or more and a flat $29.95 under $199, cooler and ice included. Alaska, Hawaii and US territories ship at UPS rates.
When will my order ship?
We ship Monday to Thursday. Order by 3 pm Central and it ships the same day.
Do members save?

Kumamoto A5 Wagyu Ribeye – Heritage-Raised, Boldly Flavored, Naturally Balanced
From the rugged landscapes and cool mountain air of Kumamoto Prefecture, the A5 Wagyu Ribeye offers a uniquely bold, beef-forward experience with the elegance and marbling expected of Japan’s top-grade Wagyu. Revered for its balance of rich flavor and clean finish, Kumamoto Wagyu is raised with deep respect for tradition, utilizing pure spring water, local feed, and time-honored care techniques to produce a ribeye that’s as soulful as it is luxurious.
Kumamoto is one of the few prefectures to preserve both Japanese Black (Kuroge Washu) and Japanese Brown (Akaushi) genetics, contributing to a Wagyu profile that is distinctively rich yet naturally lighter on the palate—perfect for diners who crave depth without heaviness.
Why Kumamoto A5 Ribeye Stands Out
🔥 A5 Grade with Balanced Marbling – Delivers BMS 10-level marbling with a flavor that’s robust, meaty, and clean-finished.
🔥 Distinct Regional Character – Kumamoto beef offers a more savory, beef-centric flavor profile, ideal for chefs who want Wagyu richness with structure and backbone.
🔥 Whole Ribeye Loins (Sold by the Case) – Offers full versatility for thick-cut steaks, dry-aging, or custom butchery programs.
🔥 Natural Farming Traditions – Raised in a low-stress environment with natural spring water and carefully managed feed, enhancing both flavor complexity and consistency.
🔥 Rare and Revered – Kumamoto Wagyu is less commonly exported, offering an exclusive option for chefs looking to differentiate their Wagyu program.
Perfect For:
✔ Steakhouses Seeking Bold Wagyu Cuts – A ribeye that delivers richness with a firmer bite and complex flavor.
✔ Omakase, Robata, or Open-Flame Grilling – Ideal for methods that bring out the natural savoriness of the beef.
✔ Wagyu Tasting Flights – A standout option when comparing regional differences in Japanese Wagyu.
✔ High-End Steak Programs & Private Dining – A rare, high-impact cut that reflects both prestige and provenance.
The Kumamoto Difference
Kumamoto’s approach to Wagyu production is rooted in balance, purity, and respect for nature. With a focus on maintaining traditional farming practices and animal welfare, Kumamoto Wagyu offers a distinctive eating experience that bridges the richness of A5 marbling with the structure and savoriness of heritage beef.
