Google Maps – Best for Maps and Everyday Navigation

Google Maps is one of the most useful apps for traveling in Japan.

Use it to find train routes, station entrances, walking directions, restaurants, hotels, and tourist attractions.

It works especially well for everyday sightseeing when you need to move between several places in one day.

If you plan to use trains often, check our beginner’s guide to using trains in Japan before your trip.

Why Google Maps Is Useful in Japan

Japan has large train stations with many exits, especially in cities such as Tokyo and Osaka.

Google Maps can help you find the right station entrance or exit and guide you from the station to your destination.

You can also save restaurants, attractions, and hotels before your trip, which makes daily planning much easier.

Important Offline Map Limitation

Download offline maps before your trip as a backup, but do not rely on them for train travel.

When Google Maps is offline, it cannot show public transportation, walking, or cycling routes.

For this reason, keep an internet connection through an eSIM, SIM card, or portable Wi-Fi if you plan to use Google Maps for trains and walking directions.

For help choosing an eSIM, SIM card, or pocket Wi-Fi, read our guide to internet access in Japan.

For more details, check Google’s official guide to using offline maps.

Why NAVITIME Is Useful for Japan Travel

How to Call a Taxi with GO

GO shows the assigned taxi and gives you a confirmation number, which helps you identify the correct vehicle.

The app operates across all 47 prefectures, although service availability varies by area.
