Navigation Apps
Google Maps — Must Have
Google Maps is the definitive navigation tool for Japan. It covers all train lines (JR, private railways, subway), buses, walking routes, and driving directions. Real-time transit information shows exact departure times, platform numbers, and transfer instructions. Download offline maps for Tokyo, Kyoto, and Osaka before departure in case you lose data connectivity underground.
Pro tip: Search restaurants by tapping the area on the map — Google shows ratings, photos, opening hours, and whether the place accepts credit cards. This replaces dedicated restaurant apps for most travelers.
Navitime for Japan Travel
A free transit app designed specifically for tourists. Navitime shows train routes, fares, platform numbers, and which car to ride for the closest exit. It also calculates whether a JR Pass saves money on your planned route. The interface is cleaner than Google Maps for complex multi-transfer journeys.
Jorudan
Another Japanese transit app with English support. Jorudan specializes in train connections and shows first/last train times — critical for planning late-night returns. It also compares routes by cost, time, and number of transfers.

Translation Apps
Google Translate — Must Have
The camera mode is a game-changer in Japan. Point your phone at Japanese text — restaurant menus, train station signs, vending machine labels, convenience store packaging — and see instant English translations overlaid on the image. Download the Japanese language pack for offline use before your trip.
Voice translation works for basic conversations: speak English, and the app produces Japanese audio. Accuracy is good for simple requests (“Where is the bathroom?” “How much is this?”) but struggles with complex sentences.
Papago
Developed by Naver (Korean tech company), Papago handles Japanese-English translations with strong accuracy for conversational phrases. Some travelers find it more natural than Google Translate for specific phrasings. Worth having as a backup.
Yomiwa (Japanese Dictionary)
A Japanese-English dictionary with handwriting recognition and OCR. Useful for looking up individual kanji characters when Google Translate’s camera mode gives confusing results. The free version covers most tourist needs.
Transit and Payment Apps
Mobile Suica — Must Have
Add a Suica card to Apple Wallet (iPhone) or Google Wallet (Android) and tap your phone at train gates, bus readers, convenience stores, and vending machines. Load yen from your credit card directly in the app. This eliminates the need for a physical Suica card — which has limited availability due to the global chip shortage.
Setup: Open Apple Wallet → Add Card → Transit Card → Suica → Add Money. Takes under 3 minutes. Works immediately at any station in Japan.
Japan Taxi (GO Taxi)
Japan’s primary ride-hailing app. Works like Uber but with licensed Japanese taxis. Available in Tokyo, Osaka, Kyoto, and most major cities. Set your pickup and destination, see the estimated fare, and pay by credit card through the app. Essential for late-night returns when trains stop running (last trains around midnight).

Food and Restaurant Apps
Tabelog
Japan’s most-used restaurant review platform — think Yelp but more trusted. Ratings above 3.5 indicate excellent quality (the scale is stricter than Western review sites). The app has English support, though some reviews are Japanese-only. Search by cuisine type, area, and budget.
Gurunavi
Another Japanese restaurant finder with English support. Gurunavi is particularly useful for making reservations at restaurants that do not accept walk-ins. Some listings include English menus and allergy information.
Google Maps (Restaurant Search)
For most tourists, Google Maps restaurant search is sufficient. Filter by rating, cuisine, price range, and “open now.” English reviews from other tourists help identify foreigner-friendly establishments.
Communication and Safety Apps
LINE
Japan’s dominant messaging app — equivalent to WhatsApp in most countries. If you make Japanese friends, they will use LINE. Some restaurants and shops offer LINE-exclusive coupons. Download it before your trip if you want to stay in touch with locals.
Safety Tips (NHK)
Free app from Japan’s national broadcaster that sends push notifications for earthquakes, tsunamis, typhoons, and severe weather in your current location. Available in English, Chinese, Korean, and other languages. Install this before arrival — earthquakes are unpredictable.
NHK World
English-language news from Japan. Useful during natural disasters for real-time information and evacuation guidance.
Apps need data — get an eSIM before you land →
Data and Connectivity
Every app on this list requires mobile data to function at its best. Japan has three main connectivity options for tourists:
eSIM (Recommended)
An eSIM installs directly on your phone before departure — no physical SIM card, no airport pickup. Providers like Airalo, Ubigi, and Mobal offer Japan-specific plans starting from around ¥1,500 for 1GB to ¥5,000 for 10GB. Most modern iPhones (XS and later) and Android flagships support eSIM. Check your phone’s compatibility before purchasing.
Best for: Solo travelers and couples who primarily need maps, translation, and messaging. A 5–10GB plan covers 7–14 days for most travelers.
Pocket WiFi
A small portable router that creates a personal WiFi hotspot. Pick up at the airport or have it delivered to your hotel. Unlimited data plans run ¥800–¥1,500 per day. The device needs daily charging and adds one more thing to carry.
Best for: Groups traveling together (share one device among 3–5 people) and heavy data users who stream video or make video calls.
Free WiFi
Available at convenience stores (7-Eleven, FamilyMart, Lawson), train stations, and some cafes. Connection requires registration, sessions time out after 15–30 minutes, and speeds vary. Not reliable enough for real-time navigation or translation while walking around.
Best for: Emergency backup only. Do not plan your connectivity strategy around free WiFi.
Shopping and Deals Apps
Tax-Free Shopping
The “Visit Japan Web” portal (web-based, not an app) handles immigration, customs declarations, and tax-free QR code registration. Complete it before arrival to speed up airport processing. Some stores accept the digital tax-free QR code instead of stamping your passport.
PayPay
Japan’s most popular QR code payment app. While setup requires a Japanese phone number for full features, some tourists report success with international numbers. If it works for you, it unlocks payments at thousands of small shops that do not accept credit cards. Worth attempting but not reliable for all visitors.

App Setup Checklist (Before Departure)
Set up everything while you still have home WiFi. Airport arrival halls are crowded and stressful — not the place to be downloading apps and configuring settings.
- Install all apps from the table above. Test that each one opens and loads correctly.
- Download Google Maps offline areas for every city you plan to visit. Open Google Maps → tap your profile → Offline maps → Select your own map. Download Tokyo, Kyoto, Osaka, and any other destinations.
- Download Google Translate Japanese language pack for offline use. Open Google Translate → tap the download icon next to Japanese. This enables camera translation without data.
- Set up Mobile Suica in Apple Wallet or Google Wallet. Add ¥2,000–¥5,000 as initial balance from your credit card.
- Install your eSIM (if using one). Most eSIM providers let you install the profile before departure and activate it when you land.
- Register on Visit Japan Web and complete immigration and customs forms. Save the QR codes to your phone.
- Save hotel addresses in Google Maps as starred locations. This makes navigation to your hotel easy even when tired or lost.
- Enable Safety Tips notifications for earthquake and weather alerts in your preferred language.
Common Mistakes
- Not downloading offline content: Google Maps offline areas and Google Translate language packs must be downloaded on WiFi before departure. Underground stations have no connectivity.
- Forgetting to set up Mobile Suica: Do this before your flight. Setting it up at a crowded airport arrival hall is frustrating.
- Relying only on hotel WiFi: Apps are most useful when you are out exploring. Mobile data (eSIM or pocket WiFi) is essential for real-time navigation and translation.
- Not installing Safety Tips: Earthquakes happen without warning. This app sends alerts in your language within seconds.
FAQ
Do I need mobile data for these apps to work?
Most apps require data for real-time features (transit times, restaurant search, translation). Google Maps and Google Translate work offline if you download content beforehand. Mobile Suica works offline for payments once set up. Get an eSIM or pocket WiFi for full functionality.
Is Google Maps accurate for Japanese trains?
Yes — extremely accurate. Google Maps shows real-time delays, platform numbers, and exact transfer times for all Japanese train networks. It is the primary navigation tool for most tourists in Japan.
What is the best transit app for Japan?
Google Maps is the most versatile option for transit directions, showing real-time train schedules, walking routes, and fare estimates across Japan. Jorudan is Japan’s most popular local transit app, available in English, with detailed platform numbers and fare breakdowns. NAVITIME for Japan Travel is purpose-built for tourists, covering trains, buses, and walking routes with station maps and accessibility information.
Can I use Uber in Japan?
Uber exists in Japan but with limited coverage. In Tokyo and Osaka, it connects you to licensed taxi companies (not independent drivers). GO Taxi (formerly Japan Taxi) has better coverage and more available cars in most cities.
Do I need a VPN in Japan?
A VPN is recommended when using public WiFi networks for security. It is also useful for accessing streaming services and websites that may be geo-restricted in Japan. Not essential for basic tourist activities if you have mobile data.
All these apps need data to work — get an eSIM before your flight and arrive connected.
