Japan's trade ministry selected Yokohama in 2010 as a Next-Generation Energy and Social System Demonstration Area, and 34 of the country's leading energy operators, electronics manufacturers and construction companies spent five years testing household energy management, storage and electric vehicles across the city. The demonstration ended in 2014 and the partners were reorganised into a new public-private body, the Yokohama Smart Business Association, to move 'from demonstration to implementation'. The city's own public page on the project publishes no result figures.
what does this mean?
The strongest source is the operator's or the city's own reporting — an official report, dataset or press release. It grades who did the looking — not how well the project went. All four grades →🎓 Lesson
A national demonstration can be simultaneously the most-cited thing a city has done and the least checkable: five years, 34 companies, and an operator page that reports the structure of the programme without a single outcome number.

Forensic record — source dossiers, gaps, hashes and the exact revision this page renders
This layer records what is known about each source, what is still missing, and the exact snapshot this page is rendering. A missing date, archive or hash stays visible as missing.
Awaiting operator and domain-expert review; publication of this revision implies neither.

Known limits of this passport
- Publisher names and source languages have not yet been classified; domains are recorded without guessing.
- Existing source notes are descriptive locators, not page- or paragraph-exact citations.
- A missing archive, publication date or content hash is shown as null rather than inferred.
- The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
