Do I need data or can I rely on WiFi?

Download offline features for all apps before you go. Japan has good free WiFi at stations and convenience stores, but mobile data makes everything easier. Rent a pocket WiFi device at the airport for 500-800 yen per day.

Which train app is actually better - Hyperdia or Google Maps?

Hyperdia is more accurate for JR lines and shows exact car positions for reserved seats. Google Maps is better for combining trains with walking directions and handles private railway lines better. Use both.

Can I use Mobile Suica with a foreign credit card?

Yes, but setup is complex. You need to change your iPhone region to Japan temporarily. Physical IC cards (Suica/Pasmo) from station machines are simpler for short trips - they work everywhere and you can refund unused balance.

What if the camera translation gives weird results?

Google Translate camera works well for printed text but struggles with handwritten signs or stylized fonts. Take a clear photo first, then point the camera. For restaurant menus, many places have plastic food displays you can point to instead.

What apps you need for traveling in Japan

Download Google Translate with camera function, Hyperdia for train schedules, and Google Maps offline before you go. These three apps handle 90% of travel situations in Japan where English isn't widely spoken.

Download Google Translate before departure. Install Google Translate and download Japanese language pack for offline use. Test the camera translation feature - it works on menus, signs, and station names even without internet.
Get Hyperdia for train navigation. Download Hyperdia (the English version) for JR train schedules and route planning. It works offline and shows platform numbers, transfer times, and costs for all JR lines including shinkansen.
Set up Google Maps with offline areas. Download offline map areas for Tokyo, Osaka, Kyoto, and any other cities you're visiting. Google Maps works better than Apple Maps for public transit in Japan and includes train delay information.
Install IC card payment apps if you have compatible phone. If you have iPhone 8 or newer with Japanese region setting, or compatible Android, set up Mobile Suica for tap payments on trains and at convenience stores. Otherwise, buy physical IC card at station.
Get Japan Travel by NAVITIME as backup. Free app that combines train routes with walking directions. Useful when Hyperdia and Google Maps disagree on the best route. Shows real-time train delays and platform changes.
Download Tokyo Metro and Osaka Metro official apps. If visiting these cities, their official apps show detailed subway maps offline and real-time service updates. Tokyo Metro app includes English station announcements.
