Semantic Coherence — The Lens

Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.

The semantic drift is low; the homepage promise of ‘new made-in-Japan’ quality and ‘traditional craftwork’ is reflected in the product sub-pages that emphasize Fukui artisans. However, there is a minor disconnect between the ‘prestigious’ positioning and the lack of detailed product descriptions or pricing on the collection pages, which usually accompanies high-end eyewear. The H1 hierarchy is consistent, though repetitive across product listings.

Semantic Coherence is read from the heading hierarchy first: what each page announces in its H1 and headings, then whether the body actually delivers on it. Below is the structure the engine mapped, followed by the clean text to check for drift between promise and reality.

Yuichi Toyama designs frames based on 5 guiding principles: Look, Think, Draw, Make, Break.
Working this way, he creates designs that are consistently unique and consciously aware of the customer.
