日亜化学工業株式会社 (Nichia Corporation)
(https://nichia.co.jp) 📸 Data Snapshot: May 29, 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.
Authority is established through technical depth and timely updates (news posted May 21, 2026, within 8 days of the audit date). While there is a lack of structured Person schema for specific researchers, the company’s historical footprint in 20th-century semiconductor innovation is documented with specific dates (1993, 1996) and market formation strategies (魔の川, 死の谷). The technical implementation is professional, though the absence of JSON-LD schema on key pages is a minor authority gap.
The site demonstrates a rare alignment where marketing claims are secondary to technical demonstrations. Claims of ‘world’s first’ or ‘brightness 100x’ are contextualized within a 30-year historical timeline and supported by current product lineup expansions in the newsroom. There are no vague ‘ROI’ claims; instead, the site offers specific luminous flux improvements for designated product series.
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.
