Japan
Useful apps for Japan: transport, maps, translation
Start with three confirmed essentials: Google Maps for transit, your eSIM provider's app for data, and Visit Japan Web for arrival paperwork. Add a translation app with camera mode and a taxi app, but check current availability and coverage yourself. Which apps you need changes if you are staying rural or travelling without data.

Details
Set up before departure, not at the airport. Buy and install your data-only eSIM at home so data works the moment you land; voice SIMs need a residence card, so visitors rarely get one. Visit Japan Web is the government portal for arrival paperwork — check its current process before you fly, since what it issues and when can change.
On the ground, Google Maps is the app most travellers use for trains, subways and buses. Treat its platform numbers, departure times and bus coverage as check-worthy rather than guaranteed, and download offline maps for subway gaps and rural areas. For Shinkansen and limited express seats, there is no single nationwide booking app: use the official app or site of the operator you are travelling with, so you can reserve and change seats without queueing at a midori-no-madoguchi counter.
For language, a translation app with camera mode reads menus, signs and product labels; voice mode handles short exchanges. Download the offline Japanese pack. LINE is how Japanese people and businesses message, so it is worth having if you are meeting anyone locally. Free Wi-Fi at stations, konbini and airports usually needs a quick email sign-up, which is another reason to have data sorted first.
