DISTINCTIVE QUALITIES: A5 Wagyu is the highest grade of Japanese Wagyu beef. Pair this fact with ribeye and you get a firm yet tender, and heavily marbled—gorgeous, rich, and juicy cut of premium wagyu beef. Kolikof Caviar & Gourmet provides its customers with only the highest grade of wagyu and will not settle for less than perfection. Award-winning and top-scoring from the Miyazaki Prefecture, this cut is superior even to Kobe beef. Pasture-raised for 16-18 months; cattle are then grain-fed for over 450 days. This prized wagyu beef is hormone-free, antibiotic-free, and non-GMO.

BEHIND THE PRODUCT: A5 Miyazaki Japanese Wagyu Boneless Ribeye, also known as a standing rib roast or prime rib, is a culinary delicacy that is produced in only the most suitable environments. The Miyazaki Prefecture is situated on the island of Kyushu, where the climate is optimum for year-round production.

SERVING SUGGESTIONS: As a single wagyu ribeye steak, sear quickly using high heat. As a roast loin, this beautiful cut of beef can be sliced in thicknesses of your preference prior to cooking, or roast whole for a most succulent prime rib. Because of the rich fat marbling, grilling A5 wagyu is not recommended unless using indirect heat.
Silken, intensely marbled, and rich with umami. The ribeye amplifies A5’s delicate fat and lingering buttery finish.

A5 Wagyu is exceptionally rich, so smaller portions are ideal. Slice into narrow strips, season lightly, and sear briefly in a very hot pan. Cook in batches, then rest briefly before serving.

The Japanese Wagyu Standard

Japanese A5 at its richest

A5 ribeye is the most marbling-forward cut in the Japanese collection. Serve in smaller portions and sear briefly.

Marbling richness
Beef flavor
Clean finish
Tenderness
Overall richness

Japanese A5 is the highest combined yield-and-quality grade. The “A” is yield grade and “5” is quality grade; Grade 5 marbling generally corresponds to BMS 8–12. Marbling still varies naturally by cut.

Japanese Provenance

What makes Japanese Wagyu exceptional

Japanese Wagyu is defined by bloodline, regional husbandry, detailed traceability, and a national grading system that evaluates both yield and eating quality.

Japan A5
GRADE

Japan A5

A5 is Japan’s highest combined grade: “A” represents carcass yield and “5” represents top quality based on marbling, color, texture, and fat quality.

Miyazaki & Kagoshima
REGION

Miyazaki & Kagoshima

These renowned Japanese prefectures are known for tightly managed Wagyu programs and highly consistent A5 beef with fine, abundant marbling.

Kobe is specific
AUTHENTICITY

Kobe is specific

Not all Japanese Wagyu is Kobe. Genuine Kobe beef must meet strict certification rules and come from Tajima cattle raised and processed in Hyogo Prefecture.

The Japanese Method

Respect the richness

A5 Wagyu is different from a conventional steak. Use smaller portions, minimal seasoning, and very brief high-heat cooking.

Portion

Plan a smaller serving than an ordinary steak. Slice chilled Wagyu into narrow strips or bite-sized pieces.

Sear briefly

Use a dry, very hot pan. Sear in small batches, allowing the Wagyu’s own fat to render. Keep seasoning restrained.

Rest & savor

Rest briefly and serve immediately, preserving the delicate, buttery center.

Why Japanese A5

The highest expression of Wagyu

Japanese A5 is about savoring extraordinary texture, marbling, and umami in a thoughtful portion.

The grading

A5 is Japan’s highest combined yield-and-quality designation, with exacting standards for marbling, color, texture, and fat quality.

The marbling

Fine intramuscular fat melts quickly and evenly, producing the silken mouthfeel that distinguishes authentic Japanese Wagyu.

The provenance

Miyazaki, Kagoshima, Kobe, Matsusaka, and other regional names represent distinct programs—not interchangeable labels.

If I don't personally love it, I won't sell it. And I'm picky.
