Essential Apps for Traveling in Japan (2026)

You need exactly four apps for Japan: Google Maps for navigation, Google Translate for menus and signs, a Suica on your phone for trains and payments (iPhone only, Android users get a physical card), and Japan Travel by NAVITIME for complex train transfers. Add the GO taxi app and the NERV disaster alert app if you want the full kit, and fill in Visit Japan Web before you fly to skip the paper arrival forms. Everything below is free.

The Four Essentials

1. Google Maps

Google Maps in Japan is excellent, and for most travellers it replaces a dedicated transit app entirely. Transit directions include exact departure times, fares, platform numbers at major stations, and which numbered exit to leave the station by. That last one matters more than you'd think: big stations like Shinjuku have over 50 exits, and picking the wrong one can add ten minutes of walking.

• Star places before your trip. Save restaurants, temples, and shops to lists while planning. On the ground, you just open the map and see what's nearby.
• Check the last train. Transit search shows the final departure of the night, typically between 23:30 and 00:30. Miss it and you're paying for a taxi or a capsule hotel.
• Restaurant ratings skew low in Japan. Japanese reviewers grade harshly. A 3.5 on Google Maps in Tokyo is often a genuinely good restaurant, so don't hold out for 4.5s like you would at home.

2. Google Translate

The camera function is the one you'll actually use: point your phone at a menu, a sign, or a washing machine control panel and it overlays English in place. It handles handwritten menus badly but printed text well.

Download the Japanese offline pack before you fly (Settings, then Offline translation, then Japanese, about 50MB). Camera and text translation then work in basement restaurants and on the Shinkansen with no signal.

The conversation mode (two-way speech translation) is genuinely useful at pharmacy counters and hotel front desks in smaller towns. In Tokyo you'll rarely need it: staff at hotels, stations, and chain stores handle basic English fine.

3. Suica on Your Phone (iPhone) or a Physical Card (Android)

A Suica is Japan's tap-to-pay card for trains, metros, buses, vending machines, and convenience stores. You'll use it 20 times a day.

iPhone users: set it up before you fly. Either add a Suica directly in Apple Wallet (tap +, then Transit Card, then Suica), or download Welcome Suica Mobile, JR East's official tourist app launched in March 2025. The app version needs iOS 17.2 or later, charges no deposit, is valid for 180 days, and can also book JR East Shinkansen seats. Top up either version with any credit card in Apple Pay.

Android users: mobile Suica requires FeliCa hardware that only Japanese-market phones have, and as of mid-2026 there is still no tourist Android app. Buy a physical Suica or PASMO at the airport ticket machines when you land (¥500 refundable deposit). It works identically.

Full details in our Suica and IC cards guide.

4. Japan Travel by NAVITIME

Google Maps handles city transit well, but NAVITIME is better for long-distance and complicated routes. It shows which car to board for the fastest transfer, walking time between platforms, and, critically for JR Pass holders, a filter that only shows routes your pass covers. It's available in English and is the app to open when you're planning Shinkansen legs or rural connections.

Worth Adding

GO (Taxis)

GO is Japan's dominant taxi app, covering all 47 prefectures with about 80% of the country's taxi-app usage. The interface is in English, it accepts foreign credit cards, and you can register with a non-Japanese phone number. You set your destination in the app, so there's no need to explain it to the driver. Short-term visitors pay a ¥200 international service charge per ride.

What about Uber? It works in Tokyo, Osaka, Kyoto, and 40+ other cities, but it dispatches licensed taxis at taxi prices, not cheaper rideshares. Since mid-2026, tourist Uber accounts in Tokyo and Yokohama are actually routed through the S.Ride taxi network. If you already have Uber installed it works fine; GO just has more cars.

NERV Disaster Prevention

Japan averages over 1,500 noticeable earthquakes a year, and your phone will occasionally blare an alert in Japanese. NERV (free, iOS and Android, full English support) delivers earthquake, tsunami, and severe weather alerts from a direct Japan Meteorological Agency feed, localized to where you're standing, with plain-English instructions. You will probably never need it. It's the best kind of insurance: free and 30 seconds to install.

SmartEX (Shinkansen Booking)

If you're riding the Tokaido/Sanyo Shinkansen without a JR Pass (Tokyo to Kyoto, Osaka, Hiroshima), the SmartEX app sells reserved seats in English, often with early-booking discounts, and links to your Suica so you tap through the Shinkansen gates with your phone. See our JR Pass guide for whether you need a pass at all.

Tabelog (Serious Restaurant Hunting)

Tabelog is Japan's homegrown restaurant review site, and its scores are far stricter than Google's: anything above 3.5 is very good, and 4.0+ usually means booked out weeks ahead. The English site works in a mobile browser (no app needed). Use it when food is the point of the evening; use Google Maps when you just need lunch nearby.

Before You Fly: Visit Japan Web

Not an app but a website (vjw.digital.go.jp), and worth 15 minutes before departure. You enter your passport, flight, and customs details online and get a QR code. At Haneda, Narita, and Kansai airports, one scan at the joint kiosk now covers both immigration and customs, which is meaningfully faster than the paper-form line after a long-haul landing.

It's optional: paper forms still exist and are handed out on the plane. But the QR route is faster at peak arrival times, and doing it from your sofa beats filling in forms on a tray table.

Apps You Can Skip

• Phrasebook apps. Google Translate's offline pack covers everything they do.
• Dedicated metro map apps. Google Maps and NAVITIME both include every line and station.
• WiFi-finder apps. The fix for patchy public WiFi is mobile data, not hunting hotspots. Get an eSIM before you land: our Japan eSIM guide covers which one and how to set it up.
• Currency converter apps. At roughly ¥150-160 to the US dollar, just knock off two zeros and take a third off. ¥3,000 is about $19.
