Yoshinoya
(https://yoshinoya.com) 📸 Data Snapshot: June 20, 2026Inspect the JSON-LD. Is there an Organization or Person schema, and does it carry sameAs links to real external profiles (LinkedIn, socials)? Missing schema or no identity declaration signals an anonymous entity.
As the official corporate domain, the authority is high. The schema_json includes BreadcrumbList and WebSite graphs, though it lacks deep Organization or sameAs links to external financial or social profiles in the provided snippet. There are no claims of ‘celebrity chefs’ or unnamed ‘experts’; the authority is derived from the brand’s physical footprint and historical presence.
Performance claims are grounded in verifiable logistics and partnerships. For example, the claim of 500 million frozen meals is presented as a news-style milestone with a commemorative campaign. Unlike competitors who claim to be ‘the best,’ Yoshinoya focuses on availability (Store Search, Delivery) and specific financial benefits (10.5% point returns).
Identity & Authority is read from the structured data first: whether the site declares who it is in machine-readable schema, with verifiable identity links. Below is the schema captured per page, then the external proof links that support (or fail to support) that identity.
