Common questions
- Does O-Ku Washington DC serve real Wagyu?
- Yes, and it says where the beef comes from. O-Ku Washington DC in Washington, DC publishes enough detail on its own materials to identify the Wagyu it sells, which is the standard this directory calls verified, last checked on August 22, 2026. That means a named Japanese brand or prefecture with its grade, an American breed status with a named producer, or an Australian producer with a marbling score.
- What kind of Wagyu does O-Ku Washington DC serve?
- Its menu discloses Miyazaki A5. Each of those is taken from the venue's own current materials rather than from a review or a listing site, and the evidence behind it is quoted further down this page.
- How was O-Ku Washington DC verified?
- By reading the venue's own current material, its menu, its site or its ordering system, and quoting the line that names the beef.
