Your Japan Rail Pass handles the trains. Your phone handles everything else. Japan's transport network is genuinely one of the most navigable in the world — once you have the right tools on your device, getting from platform to platform, station to city, and menu to meal becomes second nature within a day or two.
This guide covers the apps worth downloading before you travel, organized by what they do best. Several work offline, which matters because even with a great data connection, you'll find yourself underground or in a tunnel more often than you'd expect.
Train Planning with a JR Pass
This is where the right app makes the biggest practical difference. Japan's rail system involves multiple operators, overlapping networks and pass coverage rules that vary by service — a good trip planning app handles all of that for you automatically.
Japan Travel by NAVITIME
Japan Travel by NAVITIME includes a Japan Rail Pass mode that shows optimized Shinkansen and JR routes for pass holders, and lets you save up to 50 routes for offline access. In practice, this means you can filter routes so you only see trains your pass covers — avoiding accidentally boarding a Nozomi or a non-JR service and being charged extra. It handles trains, buses, ferries and walking directions, includes platform numbers and transfer guidance, and works across the whole country. The free version covers everything most visitors need.
Jorudan — Japan Transit Planner
Jorudan is available in 13 languages, including English, French, Spanish and German, and the free version includes a JR Pass option that limits results to trains covered by the pass. A competing app to NAVITIME with a slightly different interface — some travellers prefer Jorudan's "easy route" rating that helps you choose transfers with shorter walks between platforms. Worth downloading both and seeing which display style suits you better before you travel.
Google Maps
Google Maps includes real-time train schedules, platform information and even recommends which train car to board for an easier transfer. It shows the best station, train line, and carriage for your journey, as well as the time of the next train. It doesn't have a dedicated JR Pass filter, so it won't tell you whether a specific service is pass-covered — use NAVITIME or Jorudan for that. But for getting around cities, walking to stations and general navigation, Google Maps is reliable and familiar. Download the Japan offline map before you travel.
Smart EX
Smart EX is JR Central's official booking and ticket management app for the Tokaido and Sanyo Shinkansen, allowing you to reserve seats, manage bookings, and check train details from your smartphone — useful for checking seat availability even if you're using a JR Pass. For pass holders, Smart EX isn't your ticket — but it's useful for checking which Hikari departures have seats available before walking to the ticket office to make your free reservation.
Navigation and Offline Maps
Maps.me
Maps.me lets you download the map of Japan when connected to WiFi and use it even without an internet connection — you can also import bookmarks from Google My Maps and use them alongside built-in points of interest and custom pins, even offline. This is the direct successor to the MapsWithMe app mentioned in our original guide, now rebranded as Maps.me. It covers all of Japan in detail, uses GPS without a data connection, and is particularly useful in rural areas or when you've left your Pocket WiFi at the hotel.
Google Maps (offline mode)
Mentioned above, but worth emphasizing: downloading the Japan region for offline use before your flight means you have full map functionality even without any data connection at all.
Translation and Language
Google Translate
Google Translate's camera mode lets you hover over text and see it instantly translated on screen — perfect for restaurant menus, station notices and product packaging. It works offline as long as you download the Japanese language pack beforehand. This is the single most useful language tool for visitors to Japan. Download the Japanese language pack over WiFi before you travel, and you'll be able to photograph and translate menus, signs, vending machines and labels without any data connection. The voice conversation mode requires internet, but the camera and typed translation work offline.
DeepL
For written translation that needs to sound more natural — longer texts, emails, signs with grammatically complex Japanese — DeepL is widely regarded as producing more accurate Japanese-English translation than Google Translate. Requires an internet connection but excels for anything where nuance matters.
Payments and Money
XE Currency
The best app for quick currency conversions. The Yen's large numbers (¥13,000 versus €80) catch visitors off guard — a quick check on XE before any transaction removes the mental arithmetic. Sync the exchange rate over WiFi before leaving your accommodation each morning, and you'll have accurate conversion available throughout the day without needing a live connection.
Mobile Suica / PASMO / ICOCA
iPhone users can add a digital IC card directly to Apple Wallet and top up with a credit card, using their phone to tap in and out at train stations, buses, and convenience stores. For Android, dedicated Suica or Pasmo apps create the same card digitally. IC cards handle the metro, non-JR bus lines and local trains that your JR Pass doesn't cover. The mobile version is more convenient than the physical card because you can top up by card rather than hunting for a cash machine. This is how locals pay for short journeys that fall outside JR Pass coverage.
Safety and Arrival
Visit Japan Web
Japan's official government pre-registration platform speeds up immigration and customs arrival. Fill in your details before flying — declaration forms, immigration card information — and you'll clear the airport significantly faster than travellers filling out paperwork on arrival. From 2024, a single QR code covers both customs and immigration.
JNTO Safety Tips
Japan Travel by NAVITIME and the JNTO Safety Tips app provide real-time earthquake warnings, typhoon alerts and emergency guidance in multiple languages. The JNTO Safety Tips app is operated by Japan's National Tourism Organization and pulls live data from the Japan Meteorological Agency. Anyone spending more than a few days in Japan — particularly during typhoon season (June–October) — should have this on their phone. It's the app we recommend in our Japan earthquake safety guide for exactly this reason.
Connectivity: The App That Powers All the Others
Most of the apps above either require a data connection or perform significantly better with one. That means your connectivity solution matters as much as your app selection.
A Pocket WiFi device from JRPass.com gives you unlimited high-speed data across Japan on up to 10 devices simultaneously — your phone, your travel companion's phone, a tablet — with no SIM swapping required. This is the most reliable way to ensure every app works everywhere, including in rural areas and between stations. Alternatively, Japan eSIMs have become increasingly practical for solo travellers who want a lighter setup.
What's changed since the original version of this guide: the old advice about finding free WiFi at McDonald's and turning off data to avoid roaming costs belongs to another era. Japan has excellent mobile coverage, and having always-on data is now standard practice for visitors — which is why the apps above are better than they've ever been.
Tips for Using Your Phone in Japan
-
Download everything before you fly. Offline maps (Maps.me or Google Maps Japan region), the Japanese language pack for Google Translate, and cached routes in NAVITIME should all be set up on WiFi before departure.
-
Set NAVITIME or Jorudan to JR Pass mode. This single setting filters your route results to only show pass-covered services — the most practically useful customisation you can make.
-
Most Shinkansen seats have power outlets. N700S trains on the Tokaido Shinkansen have power outlets at every seat; older trains have outlets at window seats and row ends. If you need to charge your devices on a long journey, ask when making your reservation or check the seat map.
-
Station maps are available offline in Google Maps. This includes the internal layouts of major stations like Shinjuku and Tokyo — invaluable when you need to find a specific exit or transfer platform underground.
- Keep your phone accessible at ticket gates. If you're using a mobile IC card (Suica/Pasmo), you'll need your phone screen-up at the gate. JR Pass holders show the physical pass to the attendant at the staffed gate alongside the regular turnstile.
Frequently Asked Questions (FAQ)
1. What is the best app for navigating Japan trains with a JR Pass?
Japan Travel by NAVITIME is the most recommended option for JR Pass holders. It has a dedicated JR Pass mode that filters route results to only show services covered by your pass, preventing you from accidentally boarding a non-covered train. Jorudan (Japan Transit Planner) is an excellent alternative with a similar JR Pass filter and is available in 13 languages.
2. Does Google Maps work well for train travel in Japan?
Yes — Google Maps is now very reliable for Japan transit, showing real-time schedules, platform numbers and car recommendations. It doesn't have a JR Pass filter, so it can't tell you whether a specific service is pass-covered. For that, use NAVITIME or Jorudan alongside Google Maps.
3. What happened to the Hyperdia app?
Hyperdia discontinued its English-language service for international users. The Japan-facing Hyperdia timetable still exists in Japanese, but is no longer the practical option it once was for foreign visitors. Japan Travel by NAVITIME and Jorudan are the current recommended replacements, both available in English with JR Pass filtering.
4. Do these apps work offline in Japan?
Several of them do, at least partially. Maps.me and downloaded Google Maps regions work fully offline for navigation. Google Translate's camera and typed translation work offline once you download the Japanese language pack. NAVITIME routes can be saved for offline access. XE Currency works offline if you've recently synced the exchange rate. For the best experience across all apps, a Pocket WiFi device gives you constant data wherever you are in Japan.
5. Is a Suica card necessary if I have a JR Pass?
Not strictly necessary, but very useful. The JR Pass covers JR services, but Tokyo's subway lines and many local buses are operated by other companies and require a separate fare. A mobile Suica (or PASMO/ICOCA) handles all non-JR transport seamlessly, including convenience store payments. Adding a mobile IC card to Apple Wallet or using the Android Suica app means you never have to top up with cash.
