This listing's current published materials advertise Wagyu, but the offering does not meet our full verification standard for provenance. It carries no authenticity badge; undisclosed details remain explicitly unverified.
Why it's listed
Chef Akira Back's modern Japanese room at One&Only Moonlight Basin, serving dinner Tuesday to Saturday. Its charcoal grill lists three Wagyu steaks: a 30oz dry-aged bone-in ribeye at 205, a 16oz New York striploin at 105 and a 12oz picanha at 62, each labelled Montana. Wagyu also runs through the menu as a filet tobanyaki built on Montana tenderloin, a tartare, a taco and a fried rice, and two of the steaks return as prix fixe supplements. The menu names no ranch, no breed generation and no grade, so the sourcing claim stops at the state.
Authenticity flags
- The three Wagyu steaks are labelled only by state, as Montana, with no ranch, no breed generation and no marbling grade given. That tells you roughly where the cattle were raised but not who raised them or how the beef was graded. If provenance matters to you, ask which Montana producer supplies the grill before you order.
- The fourth steak on the charcoal grill, the 32oz dry-aged tomahawk, is bison rather than Wagyu, and it is the one item in that section sourced from South Dakota. Some listings elsewhere describe a South Dakota Wagyu steak here; on the restaurant's own menu every Wagyu cut is Montana.

Common questions
- Does Akira Back - One&Only Moonlight Basin serve real Wagyu?
- Its own current menu advertises Wagyu, and that claim was read directly on August 18, 2026. What the menu does not do is say which Wagyu: no prefecture, grade, breed status or producer is published, so the sourcing cannot be checked from outside. That is a gap in what is written down rather than a suggestion that anything is wrong with the beef, and plenty of kitchens buy carefully without printing the details.
- What kind of Wagyu does Akira Back - One&Only Moonlight Basin serve?
- Its menu discloses unknown and Montana. 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.
- Why is Akira Back - One&Only Moonlight Basin listed without a Wagyu badge?
- Because a badge here means the sourcing was checked, not that the food is good. This listing is published because the venue genuinely advertises Wagyu on its own current material, and it carries no badge because that material does not say which Wagyu. If the venue publishes the prefecture, grade, breed status or producer, the listing can move.
