How we check facts

Updated October 2026

The sources we start from

Every fact in this guide traces back to a named public source. Official and government sites come first, along with the operators’ own sites. Booking agents come next, then Wikivoyage, Wikipedia and news reports.

On file, a fact holds four things: the link to its source, a line quoted word for word from that page, the date it was read and the date it falls due for a re-check. The quoted line has to match what the live page says. The guide pages are drafted from this file of facts alone.

Following a single fact

A fact starts as a line on a source page. It is saved with its quote and its dates, and only then can a guide page cite it. The box below is one of this site’s facts exactly as it is filed.

Keeping facts fresh

Each live site is refreshed every two to three months. In a refresh, a batch of facts is held up against its source pages again. The oldest go first, together with the kinds that drift fastest: prices, fees, timetables and seasonal opening months. Source links, linked tour pages and places to stay are looked at again too.

If a source has stopped showing a fact, the fact is flagged rather than quietly removed. It is then brought up to date from that source, moved to a stronger source, or taken off the page.

Conflicting sources and gaps

Sometimes two sources give different answers. The page then shows the range and names both sources, so you can judge for yourself. If nothing can confirm a detail, the guide leaves it out instead of guessing.

How listings are picked and ordered

For tours, each booking site’s own list for Amanohashidate is the starting point. A tour is linked only after its page has been opened and checked: its title has to name the place, and nothing on it can say the tour is unavailable. A tour whose page has disappeared is never linked. The booking sites appear in a set order: first the one that had the most tours here when the site was planned, then a fixed default sequence.

Places to eat and drink are taken from Google Maps listings around the main areas. One group was opened in a browser and checked: every place featured on the five most searched pages, every place the automatic checks flagged (a name, category or area that looks wrong, or a closure) and a random fifth of the rest. The remainder rely on automatic checks of their Google Maps details, and if a single checked place turns out wrong, all of them get opened. The sources table above shows both counts. Order goes by area, then places people search for by name, then the Maps search order. Rating plays no part. Ratings shown are Google’s, each dated, and no place paid to appear.

Attractions are also found through Google Maps around the main areas, and each was opened in a browser and checked before it appears. Opening hours come from Google. Entry fees, how long to allow and notes for children are given only where a source states them. Order is by area and search interest, never rating, and anything Google Maps shows as closed is not included.

Places to stay are the ones people search for by name, the most searched first. Price, what is included and who a stay suits come from named sources shown on each card. No stay has a booking link yet: one is added only after it has been checked in a browser and the booking site has approved the site’s account.

Writing and review

The guide pages are written by an AI model, Anthropic’s Claude, using the stored facts and nothing else. Automatic checks then run over every page. The publisher reviews each page before it goes live and again after launch, and fixes whatever that review turns up.

Photos are from Wikimedia Commons and Pexels. None is AI-made; only the logo and favicon may be. Every photo is credited on the image credits page.

Latest changes

Each guide page also closes with a page history of its own, after its list of sources numbered beside the facts.
