Best apps for a Japan family trip
The genuinely useful apps for travelling Japan with kids — maps and trains, translation, and handy extras — plus how to keep them working offline.
You don’t need many apps for Japan, just the right handful. A maps-and-trains app, a translator and a couple of extras cover almost everything a family needs — and they turn confusing moments into quick ones.
Maps and trains
Google Maps is excellent in Japan for walking directions and train routes, showing platforms, times and which carriage to board. Dedicated transit apps like Japan Transit Planner (Jorudan) or Navitime are great for detailed train planning and comparing routes and fares.
Translation
Google Translate is invaluable — the camera mode reads menus, signs and food labels on the spot, and conversation mode helps with staff. Download the Japanese language pack so it works offline. See our translation-apps guide for getting the most from it.
Handy extras
- Your airline and any rail-pass or ticket apps for mobile passes and reservations.
- A currency converter for quick budgeting with older kids.
- A weather app to plan around rain and heat.
- The app for any eSIM or pocket Wi-Fi you use, to manage data.
Keep them working offline
Download offline maps for your cities and the Japanese translation pack before you go, so a patchy connection never leaves you stranded with tired kids. Pair that with an eSIM or pocket Wi-Fi for reliable data on the move.

- What apps do I actually need for Japan?
- A maps-and-trains app (Google Maps, plus a transit app like Jorudan or Navitime), a translator (Google Translate with the offline Japanese pack), and a few extras like your airline, a currency converter and a weather app.
- Do these apps work without internet?
- Partly — download offline maps and the Japanese translation pack in advance so core features work with a weak signal. For reliable live data, add an eSIM or pocket Wi-Fi.
