Why it's listed

Masami Cattle Ranch was founded in 1988 by Masami Ishida and runs its own Wagyu breeding programme across 6,500 acres of Northern California, raising bulls, cows and calves on free range. Its published programme runs three separate matings: a Wagyu bull over an Angus cow for a first generation calf, that calf's daughters bred back to a Wagyu bull for a second generation, and Wagyu over Wagyu. Cattle are fed a Japanese-style grain ration by machine and by hand, with no antibiotics, growth hormones or animal by-products. The company established its own meat-packing plant at Klamath Falls, Oregon in 1992.

01

It started before there was an industry

Masami Cattle Ranch was founded in 1988 by Masami Ishida and runs a Wagyu breeding programme across 6,500 acres of Northern California, raising bulls, cows and calves on free range. It crosses a Wagyu bull over an Angus cow for the F1 it is best known for, and also runs F2 and fullblood matings.

The date is the striking thing. American Wagyu barely existed in 1988: the exports of Japanese cattle that founded the entire national herd happened across the 1970s and the 1990s, and Japan closed live exports altogether in the late 1990s, declaring the breed a national treasure. An operation breeding Wagyu in California in 1988 was not entering a market. It was building one, at a time when almost no American customer had heard the word.

02

Its own packing plant since 1992

The company established its own meat-packing plant at Klamath Falls, Oregon in 1992, four years after founding, and that decision is probably why it is still here.

A producer selling a product nobody recognises cannot rely on the existing supply chain, because the existing supply chain is built to grade, box and price ordinary beef and will treat anything unusual as exactly that. Owning the plant meant controlling how the carcass was cut, graded and described at a point in history when no American buyer had a category to put it in.

Cattle are fed a Japanese-style grain ration delivered by machine and by hand, with no antibiotics, growth hormones or animal by-products. Hand feeding at this scale is a deliberate holdover from Japanese practice, where individual attention to each animal's intake is part of the method rather than a flourish.

Common questions

How old is this operation?
It was founded in 1988, which puts it among the earliest Wagyu operations in the United States. The exports that founded the American herd ran through the 1970s and 1990s, and Japan closed live exports entirely in the late 1990s after declaring the breed a national treasure.
What does it raise?
Chiefly F1, a Wagyu bull crossed over an Angus cow, alongside F2 and fullblood matings. Cattle are free ranged and fed a Japanese-style grain ration with no antibiotics, growth hormones or animal by-products.
If a restaurant names this ranch on its menu, what am I actually eating?
The ranch does not say, and it is worth knowing that before you assume. Its breeding page lists three separate matings, a first generation Wagyu over Angus cross, a second generation from that cross, and Wagyu over Wagyu. The page describing the beef itself never uses a generation word at all. So a menu naming this ranch tells you who raised the animal, which is more than most menus manage, and it does not tell you how much Wagyu is in the particular steak in front of you. Restaurants sourcing from here are listed as naming their producer without carrying a breed badge, and that is the reason.
