Tier 3 · Menu claim only What the tiers mean
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
Sushishima is an open, actively-operating San Antonio sushi restaurant (Stone Oak, with a second Castle Hills location) whose first-party online-ordering menu advertises multiple A5 Japanese Wagyu items: an A5 roll, Wagy-Uni nigiri, torched Wagyu nigiri, a Wagyu beef hot stone, and Wagyu stuffed mushrooms. All items are labeled only "A5 Japanese Wagyu" or "A5 Wagyu." No prefecture, brand, or producer is named on any offering, so provenance is incomplete (not disclosed). Kobe registration is not indicated.

Common questions
- Does Sushishima Japanese Restaurant serve real Wagyu?
- Its own current menu advertises Wagyu, and that claim was read directly on July 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 Sushishima Japanese Restaurant serve?
- Its menu discloses A5 Japanese. 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 Sushishima Japanese Restaurant 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.
