Google Maps Offline in Japan: What Works Without Data

Short answer: a downloaded Google Maps area of Japan will show you the map and guide you by car, but it will not give you walking, cycling or transit directions while you are offline. Google states that limitation in its own help documentation, and it matters more in Japan than almost anywhere else, because most travellers here move on foot and by train. So download the offline area anyway — then keep a separate plan for trains and for the last few hundred metres to your hotel.

This page explains exactly what an offline map covers, what quietly stops working, and which backups actually help once your signal drops in a basement station or a mountain valley.

How do you download an offline map area in Google Maps?

You need an internet connection to save the area, so do this before you leave home or while you are on hotel Wi-Fi. On iPhone and iPad, Google also notes you must be “connected to the internet and not in Incognito mode”.

The steps are almost identical on both platforms:

• Open the Google Maps app and search for a place — for example, Kyoto.
• Tap the name or address of the place at the bottom of the screen, then tap More → Download offline map → Download.
• Or tap your profile picture or initial → Offline maps → Select your own map, drag the box over the area you want, then tap Download.

The “select your own map” route is the more useful one for a trip. Japanese cities sprawl, and a box drawn around central Tokyo will miss Yokohama, Kamakura and Narita Airport unless you deliberately stretch it.

On Android you can also choose where the file lives. Google’s documentation says offline maps are saved to internal storage by default, but you can move them to an SD card through Settings → Offline maps → Storage preferences; on Android 6.0 or higher the card has to be set up for portable storage. The same Offline maps settings screen holds Download preferences, which is where you control whether downloads are allowed to use mobile data.

Google Maps may also suggest areas for you. Its help pages describe a “Recommended maps” section built from upcoming trips it finds in places like Gmail and Google Travel.

Why can’t I download an offline map of Japan?

Some travellers find the download option greyed out or missing. Google’s help page gives the general reason without naming countries: “You can’t download offline maps in some countries or regions because of contractual limitations, language support, address formats, or other reasons.”

Google does not publish a public list of which regions are excluded, and coverage has changed over time, so the only reliable check is to try it yourself. Search a Japanese city in the app a few weeks before you fly and see whether “Download offline map” appears. If it does not, that is the reason — it is not a bug in your phone, and reinstalling the app will not change it.

If the download is unavailable for the area you want, skip ahead to the offline transit apps and Wi-Fi sections below, which do not depend on Google’s offline coverage at all.

What actually works offline in Google Maps?

Google’s documentation is specific about the gap. It says: “After you download an area, use the Google Maps app just like you normally would. If your internet connection is slow or unavailable, your offline maps can guide you to your destination as long as the entire route is within the offline map.” And then the catch: “When you’re offline, transit, bicycling, or walking directions are unavailable. If you’re offline when you drive, you can’t get traffic info or alternate routes.”

One nuance worth holding onto: “offline” also covers a weak connection. If you are in a basement shopping level, on a rural line or inside a long tunnel, the downloaded area is what keeps the map drawing instead of showing grey tiles.

Why the missing transit directions matter so much in Japan

In a car-centric country, losing walking and transit directions is an inconvenience. In Japan it removes the two things you use constantly.

Train and subway routing is the backbone of a Japanese itinerary, and it is exactly the feature Google switches off when you have no data. Transfer platforms, departure times, which of several parallel operators to take, and whether a service is rapid or local — none of that resolves offline.

Walking directions are the quieter loss. Japanese addresses are block-based rather than street-based, so pinpointing a small restaurant or a side-street hotel usually depends on the blue walking line rather than a street number. Without it you still see the map, and you can still see the pin if you saved it — you just have to read the map yourself and orient by landmarks and station exits.

A practical workaround: before you go offline, load the route while you still have a connection. The screen keeps showing what it has already fetched, and a screenshot of the route and the transfer list survives regardless of signal.

What can you use for trains when you have no data?

Because Google’s offline maps do not cover transit, the useful backups are apps that store route results on the device.

Japan Travel by NAVITIME, published by NAVITIME JAPAN CO., LTD., is one of the better-known options. Its App Store listing describes transit search across “trains including JR and subway lines, airplanes, taxis, and ferries”, says the app “Allows you to save up to 50 recently searched routes” and lets you see them while offline, and lists an offline spot search that covers “Free Wi-Fi hotspots (NTT FREE Wi-Fi, FREESPOT, Starbucks, etc.), currency exchange spots, ATMs, TICs, and train stations”. The app is free to download with optional in-app purchases as of September 2026.

That last point is worth pausing on: an offline search for free Wi-Fi hotspots is a way back online, not just a map feature. If you are stranded without data, finding the nearest hotspot is often faster than trying to fix your connection.

Whatever app you choose, the pattern is the same. Search your routes while you have a connection, save them, and treat the saved copy as your fallback. A saved route is a snapshot, though — it will not know about a delay or a cancellation that happens after you save it.

Does Apple Maps work offline in Japan?

This is where the two apps genuinely differ, and it is the single most useful thing an iPhone user can know before a Japan trip.

Apple’s support documentation says offline maps require iOS 17 or later and that they “include details like hours and ratings on places, turn-by-turn directions for driving, walking, cycling, or riding transit, and estimated arrival times”. In other words, Apple lists offline transit and walking directions as included, where Google lists them as unavailable.

Two caveats before you switch apps. First, both companies limit offline maps by region, and Apple’s wording — “Offline maps are only available in select areas” — is as vague as Google’s, so check the specific area you need rather than assuming national coverage. Second, offline transit directions built from stored timetables cannot reflect a delay or a suspended line that happens while you are offline. Treat any offline transit result as a plan, not a live answer.

The sensible approach on an iPhone is to download both: the Apple Maps area for offline walking and transit, and the Google Maps area for the place data and search habits you are used to.

How long do offline maps last before they expire?

Downloaded areas are not permanent. Google’s help pages say “You must update the offline maps you’ve downloaded on your phone or tablet before they expire”, and that “When your offline maps expire in 15 days or less and you’re connected to Wi-Fi, Google Maps tries to update the area automatically.”

For a traveller, the practical reading is: download once when you book, and then check the Offline maps screen again a day or two before you fly. Refreshing on hotel or home Wi-Fi costs you nothing; discovering an expired area at Narita costs you the thing you downloaded it for.

You can also rename and delete saved areas from the same screen, which is worth doing after a trip so old city downloads are not sitting on your phone.

Apple handles this differently. Its documentation says Automatic Updates is on by default so maps stay current when details change, and an optional Optimize Storage setting means “any unused offline maps will be automatically deleted after a period of time” — useful for storage, but a reason to confirm your Japan area is still there before departure.

How do you get back online in Japan if you need to?

Offline maps are a safety net, not a strategy. Live transit is where Japan’s mapping is genuinely excellent, so most people are better off with a working data connection and offline maps as the backup.

The Japan National Tourism Organization’s connectivity page lists free Wi-Fi at Narita, Haneda, Kansai International, New Chitose, Centrair and Fukuoka airports, which means you can usually re-download or refresh a map on arrival before you reach the train.

JNTO also describes SoftBank’s Free Wi-Fi Passport, which it says offers two weeks of free Wi-Fi from 400,000 hotspots nationwide, activated by setting roaming to “SoftBank” and dialling *8180 for a password. For a longer-term connection, the same page notes you can buy a SIM card at electronics retailers such as Bic Camera or Yodobashi Camera, with plans starting around 3,000 yen for 1GB over 30 days as of September 2026, and adds that “Your phone must be unlocked to use a sim card.” Pocket Wi-Fi rental kiosks are described as available at all major airports.

Pre-trip checklist for offline maps in Japan

• Download your city areas on Wi-Fi at least a few days before departure, and check they have not expired the night before you fly.
• Draw the download box wider than you think — include the airport, day-trip towns and any onward city.
• On iPhone, download an Apple Maps area too, since it lists walking and transit directions as offline features.
• Save your key train routes in a transit app that stores results offline, and screenshot the transfers.
• Save your accommodation as a pin, with the address in Japanese where you can, so you can show it to a taxi driver or station attendant.
• Note your nearest free Wi-Fi options, so a lost connection has a fix rather than just a workaround.

Frequently asked questions

Can I use Google Maps in Japan with no data at all?
Partly. Within a downloaded area you can view the map and get driving directions, but Google’s documentation lists transit, walking and cycling directions as unavailable offline, so it is not a complete navigation solution for a train-and-foot trip.

Will offline Google Maps show train times in Japan?
No. Transit directions are among the features Google lists as unavailable offline, and that includes the departure and transfer information you would normally rely on.

Does an offline map still show my location?
Your phone’s GPS receiver does not need a data connection to fix your position, so the blue dot generally still works. What you lose is the routing and the live information layered on top of it, not the location itself.

How big is an offline map area?
Google does not publish sizes in its help pages, and the figure depends on how large a box you draw. Apple’s documentation says Maps shows the file size for a potential offline map before you download it, so on iPhone you can see the cost in storage before committing.

Should I rely on offline maps instead of buying data for Japan?
For most itineraries, no. Offline maps are a good insurance policy against dead zones, crowded networks and a flat travel-SIM balance, but the parts of Japanese travel that benefit most from a phone — train routing, live delays, restaurant hours — are the parts that need a connection.
