Google Maps

📱 Download: App Store | Google Play

Google Maps remains the strongest all-around option in Japan too. It calculates walking, bus, subway, and Shinkansen transfer routes in a single search, and as of 2024 covers Tokyo, Osaka, Kyoto, Sapporo, and Fukuoka's transit systems almost completely.

Key feature: download offline maps → check your GPS location without using data
Tip 1: save "Tokyo, Japan" for offline use before you leave. The map is roughly 200–400MB, so download it on Wi-Fi in advance to save mobile data on the ground.
Tip 2: save restaurants, convenience stores, and attractions you want to visit to a Google Maps list — saved pins stay visible even offline.
Tip 3: use "nearby convenience stores" on the go to instantly find 7-Eleven, FamilyMart, or Lawson.
Caution: rail route accuracy in Japan can be slightly lower than Navitime. Cross-check Shinkansen timetables with Navitime for the details.

Navitime for Japan Travel

📱 Download: App Store | Google Play

Navitime for Japan combines trains, subways, buses, Shinkansen, and ferries into a single optimal route — a Japan-specific app locals use every day, which is why its accuracy is so high.

Key feature: complete coverage across Tokyo, Osaka, Kyoto, Sapporo, Fukuoka, and more, right down to which platform and which exit to use at each station.
JR Pass filter: select "foreign-tourist-only passes" (JR Pass, Osaka Amazing Pass, and others) to filter for only the routes covered by that pass.
IC card balance check: check your Suica, ICOCA, or PASMO balance over NFC.
Offline maps: the premium tier supports offline route search.
Tip: during rush hours (7:30–9:30, 17:30–19:30) check "avoid crowded times" for a less packed transfer route.
Caution: core features are free, but offline maps and some detailed routes require a paid monthly subscription. The free tier is plenty for a short trip.

2. Transit IC card — Suica (mobile)

Japan's Suica transit IC card can live directly on your phone. One tap pays for trains and buses, and also works at convenience stores, vending machines, some restaurants, and coin lockers. Launched by JR East in 2001, Suica has since issued over 55 million cards nationwide.

Supported devices: iPhone 7 or later (add to Apple Wallet) / Android (Google Pay or a dedicated Suica app)
Top-up: top up in-app with an overseas Visa or Mastercard. Cash top-ups at convenience stores also work.
Where it works: all JR East and JR West lines, Tokyo Metro, Toei Subway, private lines like Hankyu/Hanshin/Kintetsu, convenience stores (7-Eleven, FamilyMart, Lawson), McDonald's, vending machines, and more
Maximum balance: up to ¥20,000
Tip: top up ¥2,000–3,000 the moment you land and get straight on a train. No need to queue at a ticket machine — just tap your phone on the reader.
Caution: Apple Pay Suica only works on iPhone or Apple Watch. On Android, add Suica through Google Pay or install a dedicated Suica app.

✅ Real-world tip: you can ride straight from Haneda or Narita into central Tokyo with Suica. At Narita, the N'EX (Narita Express) also accepts Suica.

3. Translation

Google Translate

📱 Download: App Store | Google Play

Japanese mixes hiragana, katakana, and kanji, which is exactly where camera translation shines. Point your camera at a restaurant menu, a drugstore product label, or a train sign and it instantly overlays a translation.

Camera translation: real-time (AR) translation overlays translated text right on top of menus and signs.
Offline pack: download the Japanese offline pack (about 50MB) in advance to translate without data.
Voice translation: speak in your language and hear it spoken back in Japanese — handy when talking with locals.
Translate saved photos: pull up a photo of a menu from your gallery to translate it after the fact.
Tip: translating ingredient lists on medicine at a drugstore (ドラッグストア) helps you check for allergens.

Papago (Naver)

📱 Download: App Store | Google Play

Built by Naver, Papago is especially strong for Asian-language pairs and often produces more natural phrasing than Google Translate for Japanese. It is well worth installing alongside Google Translate.

Photo translation: shoot Japanese text with the camera for an instant translation — worth comparing against Google Translate for accuracy.
Conversation mode: real-time two-way voice interpretation, useful when talking with a taxi driver or restaurant staff.
Phrasebook: save phrases you use often so you can pull them up quickly.
Tip 1: translating a restaurant confirmation email or ryokan instructions with Papago often reads more naturally than Google Translate.
Tip 2: Papago tends to give a fuller explanation for traditional Japanese dish names (sukiyaki, shabu-shabu, and others).

4. Payment apps

Cash is still king in Japan, but QR payments have exploded in recent years. They are now standard at convenience stores, drugstores, and restaurants, so setting up a payment app lets you handle most shopping without cash.

PayPay

📱 Download: App Store | Google Play

Japan's largest QR payment app. Jointly funded by SoftBank and Yahoo Japan, it launched in 2018 and quickly rose to the top of the market. It now has over 60 million users and is accepted widely at convenience stores, drugstores, restaurants, and tourist-site shops.

Setup: download the app, register an overseas Visa/Mastercard card, and you can start using it right away.
Exchange rate: applies the live exchange rate at checkout. Your card issuer's foreign transaction fee (typically 1.5–2%) may also apply.
Points: earn PayPay points on every purchase — some merchants run 20–30% cashback campaigns.
Accepted at: 7-Eleven, Lawson, FamilyMart, Don Quijote, Matsumoto Kiyoshi, Yodobashi Camera, and many ramen and sushi chains, among others.
Tip: drugstores sometimes run extra 5–10% cashback promotions for PayPay payments.
Caution: some smaller restaurants don't accept PayPay. Always carry ¥3,000–5,000 in cash as backup.

LINE Pay

📱 Download: App Store | Google Play

A payment service built into the LINE app. LINE is used across Japan the way WhatsApp or Messenger is used elsewhere, and LINE Pay is its connected QR/barcode payment service.

Setup: install LINE, then activate LINE Pay from the "Wallet" tab at the bottom.
Overseas cards: Visa and Mastercard from abroad can be linked.
Where it works: fewer merchants than PayPay overall, but LINE-affiliated stores (some restaurants and retailers) sometimes offer exclusive discounts.
Tip: since you'll likely already have LINE installed to message a local friend or your accommodation host, setting up LINE Pay alongside it is an easy win.

5. Restaurants & cafés

Tabelog (食べログ)

📱 Download: App Store | Google Play

Japan's largest restaurant review platform. Launched in 2005, it now lists more than 8.6 million restaurants nationwide. A score of 3.5 or above signals a spot locals genuinely rate; 3.8 or above means fierce competition for a reservation.

How to search: find nearby restaurants based on your current location, and filter by cuisine (sushi, ramen, yakiniku, shojin ryori, and more).
Reservations: some restaurants let you book directly in the app. Use the "English menu available" filter to reduce the language barrier.
Rating context: a score of 3.5+ puts a restaurant in roughly the top 3–5% overall — a very high bar. 3.2–3.4 is still a genuinely good restaurant.
Booking window: popular sushi and izakaya spots can be booked out months in advance on Tabelog. Start reserving 2–3 months before your trip.
Tip: filter for "lunch service" (ランチ営業) to find restaurants offering special lunch menus — often 30–50% cheaper than the same dish at dinner.
Caution: Tabelog has faced score-manipulation controversies. Prioritize restaurants with recent reviews (last 6 months) and a high review count.

6. Accommodation booking

Agoda

📱 Download: App Store | Google Play

Asia's largest hotel booking platform. Compare everything from business hotels to high-end ryokan across Tokyo, Osaka, and Kyoto.

Price guarantee: get the difference refunded if you find the same room cheaper elsewhere.
App-only discounts: booking through the app often unlocks an extra 5–10% discount coupon.
Ryokan specialist: strong for traditional Japanese inns, with clear details on whether breakfast and dinner are included.
Tip: ryokan-dense hot spring areas like Hakone, Nikko, and Kinosaki are often cheaper on Agoda than booking directly.

Booking.com

📱 Download: App Store | Google Play

A global accommodation booking platform. Use it for hotels, guesthouses, and apartments all across Japan.

Free cancellation: most listings offer free cancellation, which gives you flexibility if your plans change.
Genius discounts: book frequently and your tier rises, unlocking further discounts.
Tip: during peak season in Tokyo and Osaka (cherry blossoms in March–April, autumn foliage in November) book at least 2–3 months ahead.

7. Weather

AccuWeather

📱 Download: App Store | Google Play

A globally trusted weather app. Japan has distinct seasons, so checking the weather matters — especially given typhoon season (June–September) and the sudden shifts of cherry blossom season in spring.

Hourly forecast: hour-by-hour precipitation probability and temperature, so you know ahead of time whether to bring an umbrella.
Air quality: check the pollen index during Japan's cedar pollen season (February–April).
Typhoon tracking: forecasts a typhoon's path and intensity up to three days ahead.
Tip: pick a clear day during your Tokyo stay for a day trip to Nikko or Hakone — the views are far better.

8. Emergency & safety

Safety Tips (official JNTO app)

📱 Download: App Store | Google Play

An official disaster-alert app built by the Japan National Tourism Organization (JNTO). It delivers earthquake, tsunami, typhoon, and volcano alerts instantly in 14 languages. Japan is one of the most seismically active countries in the world, so install this app and make sure notifications are enabled.

Earthquake early warning: for a magnitude-5+ earthquake, it detects the initial P-wave and sends a 10–30 second warning before the main S-wave shaking arrives.
Tsunami alerts: if you're traveling near the coast, check tsunami evacuation routes right on the in-app map.
Shelter information: GPS-guided directions to the nearest temporary shelter.
Multilingual disaster info: understand the situation in your own language even if you don't read Japanese.
Tip: when an earthquake alert sounds, take cover under a table and protect your head. If you're in an elevator, press every floor button and get off at the nearest one.

9. Transport & tours

Klook

📱 Download: App Store | Google Play

A platform for pre-booking tours, activities, and theme park tickets across Japan. It's often cheaper than buying on the spot, and some tickets come with fast-track entry that skips the queue.

Tokyo Disneyland / DisneySea: buying tickets in advance on Klook reduces the risk of sellouts.
Universal Studios Japan (USJ): the Express Pass requires advance booking.
Tokyo Skytree / Tokyo Tower: typically 10–15% cheaper than buying on site.
Narita/Haneda airport transport: book Skyliner and limousine bus tickets through Klook too.
JR Pass and regional passes: compare and book various Japan regional passes.
Tip: listings marked "Instant Confirmation" issue your ticket immediately after booking.

App installation checklist

Why an eSIM is essential for a Japan trip

No matter how well you set up your apps, they're useless without data. Real-time directions in Google Maps, PayPay payments, and Safety Tips earthquake alerts all need an internet connection. Picking up pocket Wi-Fi or a physical SIM at a Japanese airport can mean a 30-minute to an hour wait during peak season.

Install an eSIM ahead of time and you can use every app on this list the moment your plane lands.
