Source-checked Japan

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.

We cite official race, temple, town, and business sources directly in each article's Source Ledger.

What remains unverified

Every article has a "What we could NOT verify" section. We never hide it, even when the section is still empty.

Mt. Fuji 100: Where to Stay Before and After the Race — A Practical Guide for Runners and Their Families

Checked

The official Mt.FUJI100 English site identifies Fuji Hokuroku Park as the main venue and names two event accommodation options: PICA Fujiyoshida and Mt. Fuji Resort Hotel. For the 2026 event, the related packages went on sale on December 3 in Japan and December 10 for overseas customers. The 2027 race dates, accommodation packages, and transport arrangements have not yet been announced, so confirm the latest official information before booking.

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

  1. Check — every claim is traced to a primary or official source before it is written down as fact.
  2. Separate uncertainty — anything we could not confirm is labelled and kept separate from confirmed facts, never blended in.
  3. Publish — an article only goes live once verification is complete for its confirmed claims and its unconfirmed items are clearly marked.
  4. Correct — mistakes found after publication go into the public corrections log.
