American Wagyu began with a bold idea combining Japan’s legendary Wagyu genetics with American ranching expertise. In 1976, the first Wagyu bulls arrived in the U.S., marking the beginning of a decades-long journey to create something extraordinary for the American Consumer..
Through careful crossbreeding with Angus and other American breeds, ranchers worked to balance the tenderness and marbling of Wagyu with the size and efficiency of traditional U.S. cattle. The results were remarkable: beef that carried the melt-in-your-mouth richness of Wagyu and the hearty flavor of Angus that you’ve come to expect.
In 1997, The Japanese Government banned all exports of live animals including semen and embryos after declaring Wagyu a National Treasure. This locked the genetics of the American herds to those animals imported in the 1976 and the early 1990’s. Because of this ban, these original genetics became even more valuable, pushing breeders to develop new ways of taking those genetics to the next level. By using artificial insemination and IVF techniques, these pure genetics were refined by selective breeding to replicate the most desirable traits to produce superior breeding bulls and heifers and then make available to any breeder the improved strains of the fullblood Wagyu. You find Fullblood breeders whose sole business model is developing the best genetic traits to help farmers and ranchers raise the best Wagyu meat possible, whether they raise Fullblood, American or both. Traits that truly define the quality of American Wagyu.
Today, there is estimated to be around 5,000 DNA certified Fullblood Wagyu cattle in the county and another 30,000 Wagyu-influenced (hybred) cattle. Both are being utilized by American Wagyu breeders to further refine and better their herds. The combination of these two genetics continue to set the gold standard for premium “Better than Prime” beef.

American Wagyu is typically a cross between Japanese Wagyu and Angus, giving it a richer flavor and better marbling than conventional beef but a firmer bite than pure Japanese Wagyu. Japanese Wagyu comes from closed, centuries‑old bloodlines with unmatched delicacy and ultra‑fine marbling, while American Wagyu is crafted for a more robust, familiar American steak experience.
Currently, we only offer 100% Japanese fullblood animals at this time. We raise the Japanese Black (Kuroge Washu)...think Kobe Beef. Each raised with verified lineage and ethical practices for consistent quality and flavor. We will notify you when our American Wagyu becomes available.
If we decide to move forward with the development of an American Wagyu herd, all animals whether on our farm or with partners, will be raised and cared for humanely, without hormones, antibiotics, or rushed feeding methods, ensuring clean, rich flavor as is our herd of 100% Fullblood Wagyu are.
American Wagyu has a richer, beef‑forward flavor with a firmer bite, thanks to its Angus influence. It’s buttery and well‑marbled, but still tastes like a classic American steak—just elevated. In contrast, 100% Japanese Wagyu is far more delicate, with ultra‑fine marbling that melts instantly, creating a silky, almost creamy texture and a deep umami sweetness. American Wagyu is bold and hearty; Japanese Wagyu is luxurious and melt‑in‑your‑mouth.
All our animals are ID tagged and given a QR code that contains pictures of the animal and its Japanese ancestry - both Paternal and Material. Individual cuts will also contain the same QR code so you know you are getting what you are paying a premium to get. Transparency guarantees you are getting what you expect. We don't sell Fake Wagyu.
