How this site decides what to tell you

What this site is

Wayfinding, not a travel blog. airport.tokyo answers one question — how do you get from Tokyo's airports to where you are going — and it answers it with numbers you can act on: fares, travel times, first and last departures. It is a tool, not a reading experience.

That shapes everything below. A tool is only worth using if you can trust the numbers in it, and if you can see how they got there.

How our numbers work

Every fare, travel time and first/last departure on this site is verified against the operator's official source — fare table PDFs, official station timetables, official fare-search systems — and carries a verification date. We do not copy numbers from other travel sites.

When we cannot verify a figure from a primary source, we say so or leave it out. Indicative ranges (like hotel prices) are labeled as such.

Where a fact matters and the operator has not published it, we mark it Unverified rather than filling the gap with a plausible guess. You can see this in practice on our ride-hailing guide, where several details about signing up are marked that way because the operators do not state them.

How we order things

We do not rank options by preference. There is no “best” taxi app or “winning” eSIM here, because the right choice depends on your trip, and a ranking would quietly substitute our judgement for yours. We set out the facts, with their sources and dates, and leave the choice to you.

Some pages still have to put things in some order — a list has to start somewhere. Where that happens, the rule that produced the order is published on the page itself, it is mechanical, and it is applied the same way to everyone. Our eSIM page lists providers alphabetically. Our ride-hailing guide orders apps by whether the app you already use works in Japan, then by how many languages it supports. Neither page carries a “recommended” badge, because neither order is a recommendation.

No order on this site has ever been influenced by a commercial relationship, and the structure is designed so that it cannot be.

Money

This site currently carries no affiliate links. We are not paid a commission by any operator, booking platform or provider mentioned on this site, and nothing you read here has been placed or ranked in exchange for payment.

If we introduce affiliate links in the future, we will disclose them clearly on every page where they appear, and they will never affect how we order options or the figures we publish. The full statement lives in our terms.

What we will not list

We only point you towards operators licensed to carry paying passengers. We do not list unlicensed operators — in Japan, being carried for money by a driver with no licence is an offence, and the drivers who approach arriving passengers at the airport are exactly that.

The test we apply is whether the operator holds a licence, not what colour the number plate is. Japan's transport ministry sets out both: passenger transport for a fare normally runs on green commercial plates, but there are licensed services that run on white private plates too. Treating plate colour alone as the test would be wrong in both directions, so we do not. The detail is on our ride-hailing guide.

Corrections

When we get something wrong, we fix it — and we say that we fixed it. We would rather carry a visible correction than a quiet edit.

• If we cannot verify a figure against a primary source, we do not publish it — or we label it clearly as unverified.
• Corrected figures carry the primary source's own reference date where possible, so you can tell how current the number is.
• A promise we cannot keep gets withdrawn rather than left standing. We had said we would publish a ranked eSIM comparison “once our review is complete”; we no longer rank providers, so we removed the promise instead of leaving it there unfulfilled.
