Your smartphone can make or break your Japan trip. The right apps will save you time, money, and stress. Here are the 10 best travel apps for Japan — all free.
- Google Maps
The essential navigation app. Works excellently in Japan and includes train routes, walking directions, and estimated fares. Download offline maps before you go in case you don’t have data. Use it for everything.
- Google Translate
The camera translation feature is a game-changer in Japan. Point your phone at a Japanese menu, sign, or document and it translates in real time. Not always perfect but good enough to understand what you’re looking at.
- Japan Official Travel App
The official app from the Japan Tourism Agency. Includes maps, emergency information, and useful guides for tourists. Good for offline use.
- Suica / ICOCA App
Add your IC card to Apple Wallet or Google Pay and never fumble for your card at the ticket gate. Works at trains, subways, buses, and convenience stores.
- Hyperdia or Navitime
Train route planners designed specifically for Japan’s rail network. More detailed than Google Maps for complex train journeys involving multiple companies and types of trains.
- PayPay
Japan’s most popular payment app. Increasingly accepted at restaurants and shops. Useful for places that don’t take foreign credit cards.
- LINE
Japan’s dominant messaging app. Many restaurants and services use LINE for reservations and communication. Worth installing even as a visitor.
- Tabelog
Japan’s restaurant review app — like Yelp but for Japan. In Japanese, but Google Translate makes it usable. Essential for finding good local restaurants beyond the tourist areas.
- Japan Weather App (tenki.jp)
Japan’s most accurate weather app. Particularly useful for tracking typhoons (August–October) and checking conditions if you’re visiting mountains or rural areas.
- NHK World
NHK’s English-language news and information app. Useful for understanding current events, emergency information, and learning more about Japanese culture and society.
Bonus: Airalo or similar eSIM app
Buy and activate a Japan data eSIM before you travel. Cheaper than roaming and more convenient than buying a SIM at the airport.
