The oldest of the three
Omi beef has been eaten in Japan since the 1590s — long before wagyu was graded, branded or exported. It is the original.

Omi wagyu
One of Japan’s three finest wagyu.
Kobe and Matsusaka are the names people know abroad. Omi is the oldest of the three — raised in Shiga prefecture on the water of Lake Biwa, and prized in Japan for more than four centuries.

- Omi What we sell
Fine, even marbling
Thin threads of fat run right through the muscle, so it melts at a lower temperature and stays tender however you cook it.
A5 — the top grade
Every Omi cut we stock is A5, the highest grade in the Japanese system, judged on yield and on four separate measures of quality.
The range
Wagyu, and everything you need to cook it.
Steaks and slices in the cuts Japanese kitchens actually use, BBQ sets for a table of friends, and the rice and grill that go with them.
