How This Directory Was Built

A reproducible editorial process

Start with a national baseline, then add only current primary-source evidence

1. Crawl all 47 JSS prefecture sections and establish 1331 sake-marked baseline records.
2. Join the matching English detail path for official English producer and label names.
3. Reconcile current prefectural member material and regional NTA brewery maps against the baseline.
4. Review national and monthly clear-sake licence actions; add a site only when a current producer or public-body source also confirms it.
5. Treat succession, incorporation and relocation as record updates. Retain distinct production sites, and retain co-located rows only when current sources establish distinct licensed operators.
6. Fix prefectures from Hokkaido to Okinawa and share record IDs and order across all languages.

Not translating can be a quality control

The 65 records without an official English name retain Japanese. We do not infer readings or corporate English names. The Thai edition uses official English brewery and label names where available, otherwise Japanese.

Checked 2026-07-27: 1403 records across 47 represented prefectures, 1401 recorded Japanese label names, 6 sites with no confirmed public representative label, and 8 succession, operator, address or label updates. This is an editorial directory built from public primary sources, not a legal register of every clear-sake licence.
