F1 Rokko Himegyu Ribeye 

Description:
The Rokko Himegyu Ribeye is a rare expression of Japanese craftsmanship and tradition, born from the unique Kozatsu category of Wagyu. Kozatsu (meaning “crossbreed” in Japanese) refers to cattle produced when one parent is Fullblood Wagyu and the other is a different breed—in this case, the Holstein dairy cow, prized by chefs for its clean, beef-forward flavor. Unlike Wagyu raised solely for achieving the highest marbling scores, Kozatsu beef strikes a balance between indulgence and purity, offering a flavor that is at once approachable and deeply satisfying.

Produced by Ushi Kobe Farm in the Nishi Ward of Kobe City, Hyogo Prefecture, this program began in 1968 when six farming families united with a mission: to raise cattle with respect for their animals, their land, and their community. Today, the cattle are nurtured on crisp spring water drawn from 120 meters beneath the Rokkō Mountains and a nutrient-rich diet of grass, barley, corn, beer lees, and sake lees sourced from the historic Hakutsuru Sake Brewery.

Taste Profile:
The F1 Rokko Himegyu Ribeye is leaner than A5 Wagyu, yet still adorned with a delicate marbling that creates an elegant melt-in-your-mouth texture. The Holstein influence brings a clean, savory backbone, while the sake lees impart a gentle sweetness and layered umami you won’t find in other crossbreeds.

• Marbling: Subtle but silky, giving richness without excess

• Texture: Refined and tender, yet structured enough to savor every bite

• Flavor: A harmony of savory depth, clean beefiness, and delicate umami with a finish that lingers gracefully

Why It’s Special:

• Authentic Kozatsu beef (Wagyu × Holstein cross) — a rare category in Japan

• Raised in Kobe City with the same meticulous care as Kobe Beef

• Balanced flavor — not as fatty as A5 Wagyu, not as plain as commodity beef

• A story of sustainability, animal welfare, and heritage dating back to 1968

This is steak for those who crave both knowledge and flavor — a ribeye that tells the story of Japan’s evolving beef culture while delivering an unforgettable dining experience.
