株式会社 山内コーポレーション (Yamauchi Corporation)
(https://yamauchi-corp.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.
A significant authority gap exists due to the total absence of structured data (schema_json is null), failing to technically validate its entity as a LocalBusiness or Organization. While the founder, Yoshiyuki Yamauchi, is named with a specific birthdate and educational history, there are no SameAs links to professional registries or social profiles to confirm his digital footprint. The technical implementation of the site lacks an H1 tag on the homepage, which contradicts the company’s claim of attention to detail and ‘visualization’ excellence.
The site makes a massive claim of having the ‘Japan’s No. 1 Visualization Estimate’ with ’60 pages of explanation,’ yet provides no downloadable sample or visual evidence of this document’s depth. The ‘Future Responsibility Construction’ claim is a marketing promise that remains unsubstantiated by any third-party warranty documentation or insurance details. While drones and infrared cameras are mentioned as tools, there are no specific data outputs or report examples shown to prove their effective application.
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.
