Japan is one of the easiest countries to navigate with a smartphone — the right apps make the difference between seamless and stressful travel. Here are the apps that actually matter.
Navigation & Transport
Google Maps: Works well for walking navigation and transit routing in Japan. Download offline maps for Tokyo and Kyoto before arriving. The transit directions now include bus routes and even tram options. Hyperdia: The gold standard for train routing — tells you which platform, car, and exact transfer time. More detailed than Google Maps for complex multi-transfer routes. Free with a slightly dated interface. Navitime Japan Travel: Combines bus, train, and taxi options — good for areas Google Maps doesn't cover well. Japan Official Travel App (JNTO): JR Pass reservation management, multilingual support, and tourist information. Use alongside Google Maps rather than instead of it.
Language & Translation
Google Translate: Camera translation feature (point at menus, signs, packaging — it translates in real-time) is genuinely useful. Works offline if you download the Japanese language pack. DeepL Translate: More accurate for complex sentences than Google Translate. Useful when typing out longer text. Papago: South Korean app that many argue has better Japanese translation quality. Good alternative.
Food & Restaurants
Tabelog: Japan's dominant restaurant review site (like Yelp but more reliable). Scores above 3.5 indicate quality; above 4.0 is exceptional. English interface available but some areas are Japanese-only. Gurunavi: Restaurant booking with English interface — good for making reservations. Google Maps restaurant reviews: For tourists, Google reviews are increasingly useful and English-language. Not as detailed as Tabelog for Japanese cuisine.
Convenience
Suica (JR East): Add Suica to Apple Wallet or Google Pay for tap-to-pay transport and convenience store purchases. PayPay: Japan's dominant QR payment app — increasingly accepted at restaurants, taxis, and markets where credit cards aren't. Load with Japanese bank or Visa. LINE: Japan's dominant messaging app — many restaurants and services communicate via LINE. Download before your trip. Yamap: Offline topo maps for hiking — essential for mountain trails.
Information & Planning
Japan Official Travel App: Real-time tourist info, multilingual support. NHK World: English news, weather, and cultural programming from Japan's public broadcaster. JapanTravel by NAVITIME: Curated guides and booking for tourist activities. Airbnb/Booking.com: Standard accommodation — both work normally in Japan.
