A source-checked way to discover the Japan that English travel guides miss.
We publish practical, narrow-topic guides only after checking claims against primary sources — and we show you what we could not confirm, not just what we could.

Our Yuasa soy sauce guide was verified against primary sources on 2026-07-19. Each published article shows its own last-checked date and a "What we could not verify" section.
We cite official race, temple, town, and business sources directly in each article's Source Ledger.
Every article has a "What we could NOT verify" section. We never hide it, even when the section is still empty.

Soy Sauce Pilgrimage in Yuasa, Wakayama: The Town Where Japanese Shoyu Began
Checked
Yuasa, a small port town in Wakayama Prefecture, is where Japanese soy sauce brewing is said to have originated in the 13th century. You can walk its preserved merchant district, visit working breweries that still ferment in cedar barrels, and do it as a half-day stop between Koyasan and Shirahama.

How verification works
- Check — every claim is traced to a primary or official source before it is written down as fact.
- Separate uncertainty — anything we could not confirm is labelled and kept separate from confirmed facts, never blended in.
- Publish — an article only goes live once verification is complete for its confirmed claims and its unconfirmed items are clearly marked.
- Correct — mistakes found after publication go into the public corrections log.
Source-checked Maps
Each article that has one links to a map showing only pins we have verified — nothing pending is shown as if it were confirmed.
