Japan Trip Planner

Name on the App Store: 旅行达人 - 日本旅游行程规划

It works out everything about your trip that can be worked out, and tells you straight what can't.

Download on the App Store (China)
  • Free (AI features cost credits per use)
  • iOS 17.0 or later
  • v1.3 · updated 2026-09-20

The app interface is available in English, as well as Simplified Chinese, Traditional Chinese, Japanese and Korean.

What it can't do

This section isn't a disclaimer. It's part of the product.

  • Fares for some legs can't be calculated. JR East has no publicly available fare data. Odakyu and Keio have only licensed their data for a specific contest. Osaka Metro and the Kyoto Municipal Subway don't allow their data to be republished. These are licensing problems, not technical ones. The app shows how big the gap is, instead of passing off an estimate as the real number. When none of the legs can be calculated, that line says it can't be calculated. It doesn't show ¥0.
  • Accommodation and meals only get a range estimate. They're marked as estimates and shown separately from transport costs, which are marked as exact.
  • The pilgrimage spot database has only 51 entries. It doesn't cover all of Japan.
  • Fares you enter yourself don't count toward the total. You can fill in the legs we can't calculate, and other users can vote that they agree. But your entry is shown separately and marked as user-entered, and it doesn't go into our transport total. That line only includes what we can calculate ourselves.

What it does

On an anime pilgrimage to Tokyo, the most expensive thing isn't the plane ticket. It's getting the plan wrong.

Japan Trip Planner does one thing: it works out everything about your trip that can be worked out, and tells you straight what can't.

Who it's for, and what problem it solves

The real problem with independent travel isn't finding guides. It's that there are too many, and they all push you to buy something. "The XX ticket is a must-buy." "The XX pass is great value." Every article you find says so, but none of them did the math for your itinerary.

This app works the other way round: it does the math first, then gives a verdict, and the verdict may be "don't buy."

"Price: ¥600 (JPY). This trip uses ¥390 of it. 2 more legs have no fare data, but each costs at least ¥180. So you save at least ¥150."

When the pass won't pay off, it says: "You'd waste ¥210. Don't buy it."

The advice doesn't depend on who pays us, because we have no affiliate links.

Every entry says who said it and when it was checked

For each of the 51 pilgrimage spots (25 in Tokyo; 14 in Kyoto, Osaka, Nagoya and Toyohashi; 4 in Washinomiya; 8 in Oarai), the coordinates, opening hours and admission fees each list their own source and verification date.

Regular closing days are written out exactly, including rules like "closed Mondays, but if a Monday is a Japanese public holiday, open that day and closed the next weekday instead." The app also tells you directly which day is the nearest closing day.

Things you'll actually use during the trip

  • Which stop you're at now, and which place is most worth going to next (sorted by earliest closing time first, not by what's nearest)
  • Ask-for-directions board: the original Japanese sentence to show the other person, with the Chinese underneath. It all works offline
  • Spending check: what we said this trip would cost, and what you actually spent. You can see at a glance which category the difference is in

Privacy and data

Your itinerary, checklists, expense records, photos, camera angles and private notes are only saved on this device. We can't see them.

Only two things leave the device, and only when you actively ask:

  1. What you tell it on the home screen (along with a summary of the preferences the AI has remembered) is sent to plan your itinerary
  2. When you tap to identify a place, that screenshot is sent for recognition

Separately, the server holds your credit balance and purchase history. In-app purchases require that.

Pricing

Trip planning, exact fares, "don't buy" verdicts, the ask-for-directions board and the spending check are always free. No subscription needed.

AI features (place recognition from photos, AI itinerary planning) cost credits each time you use them. A subscription doesn't unlock any features. It only lowers the price per credit.

About languages

The text in pilgrimage spot entries (names, captions, location notes) follows your interface language. Simplified Chinese, Traditional Chinese, Japanese, English and Korean are all available.

Only text quoted from official pages stays in the original Japanese. It's copied as-is, not translated. Japanese place names also stay as they are in every language, because on the spot you need to match those characters against the signs.

Questions

Is the Tokyo Metro 24-hour ticket worth buying?

It depends on how much of it you'd actually use on this trip. The app works it out from your itinerary. For example: "Price: ¥600 (JPY). This trip uses ¥390 of it. 2 more legs have no fare data, but each costs at least ¥180. So you save at least ¥150." When the pass won't pay off, it says so directly: "You'd waste ¥210. Don't buy it." The advice doesn't depend on who pays us, because we have no affiliate links.

Are the fares real or estimated?

They're labeled separately. Transport costs are calculated from real published fares and marked as exact. Accommodation and meals are given as a range and marked as estimates. Legs we can't get a commercial-use license for are flagged, and the app tells you how big the gap is instead of passing off an estimate. When none of the legs can be calculated, that line says it can't be calculated. It doesn't show ¥0.

Which lines can't it calculate fares for, and why?

JR East has no publicly available fare data. Odakyu and Keio have only licensed their data for a specific contest. Osaka Metro and the Kyoto Municipal Subway don't allow their data to be republished. These are licensing problems, not technical ones. The app marks the gap and won't pass off an estimate as an exact figure.

Are the opening hours for the pilgrimage spots accurate?

Each of the 51 pilgrimage spot entries (25 in Tokyo; 14 in Kyoto, Osaka, Nagoya and Toyohashi; 4 in Washinomiya; 8 in Oarai) gives a source and a verification date for its coordinates, opening hours and admission fee. Regular closing days are written out exactly, including rules like "closed Mondays, but if a Monday is a Japanese public holiday, open that day and closed the next weekday instead." The app also tells you directly which day is the nearest closing day.

I don't speak Japanese. How do I ask for directions once I'm there?

Use the ask-for-directions board: it shows the original Japanese sentence for the other person to read, with the Chinese underneath, and all of it works offline. Japanese place names also stay in Japanese in every interface language, because on the spot you need to match those characters against the signs.

Does the app upload my itinerary and expenses?

Your itinerary, checklists, expense records, photos, camera angles and private notes are only saved on this device. Only two things leave it, and only when you ask: what you tell it on the home screen (along with a summary of the preferences the AI has remembered) is sent to plan your itinerary, and when you tap to identify a place, that screenshot is sent for recognition. Separately, the server keeps your credit balance and purchase history, which in-app purchases require.
