Methodology: how we compare and decide

How this site works

Every price, time, fee, and rule on this site comes from an evidence ledger entry with a source URL, a retrieval date, and an expiry date. When an entry expires, the page that uses it is flagged and refreshed — expired numbers do not stay up. The full ledger is published on the sources page, generated from the ledger itself rather than transcribed, so it cannot fall behind the pages it backs.

Anything we have not personally verified is marked “Not yet tested”. First-person claims appear only when a human has verified the underlying evidence.

Three tiers, not two

The obvious policy — publish only what we confirmed at the source — turned out to be the wrong one. Applied honestly it strips out exactly the figures a reader most wants, because a fair number of Japanese operators publish fares on pages an automated check cannot read. A guide to a mountain valley with the shuttle fare removed is not a more honest guide. It is a worse one.

So figures are handled in three tiers:

  1. Read at the source. Published plainly, with the date we read it.
  2. Not confirmable at the source, but reported elsewhere. Published with a label saying so, why we could not confirm it, and where you can check.
  3. No basis anywhere. Not published. Where a fixed price simply does not exist — hotel rates, metered taxi fares — we say why instead of leaving a suspicious gap.

Tier 2 is a warning to you, not a licence for us. It has already earned its keep: a bathhouse admission we carried as an unconfirmed figure turned out, once the source became readable, to be higher than the secondary sources said. Without the label, a reader would have budgeted on a wrong number. The correction stays on the article that carried it, because a number quietly fixed teaches nobody anything.

Affiliate links are disclosed at the top of each page and next to the links themselves, and always carry rel="sponsored nofollow". We do not accept payment for placement, and a commission never changes a recommendation — see our disclosure.

Several guides carry no affiliate link at all, deliberately. Where the only thing to buy is a car-park ticket at the gate, a government-run ballot, or an admission sold by the city itself, there is nothing a commission link could honestly sell you.
