During a trip to Japan, there are many situations where you will use Google Maps, such as searching for tourist spots and hotels, checking train transfers, and confirming walking routes.
However, many people may wonder, "How much data does Google Maps use?" "What GB do I need for a one-week trip to Japan?" "Is 1GB enough if I'm just using the map?"
When using only Google Maps, it does not consume as much data as video apps. However, the data usage varies depending on the frequency of map displays, navigation time, Street View, and photos of nearby facilities.
In this article, we will explain the necessary data capacity for using Google Maps during a trip to Japan, based on usage time and the number of travel days. We will also introduce ways to reduce data usage and how to choose a suitable Japan eSIM for your trip.
How much data does Google Maps use?
The data usage of Google Maps varies depending on the features used and the number of times the map is loaded.
If you are only searching for maps or checking routes for a short time, the data usage is relatively low. On the other hand, frequently displaying satellite images, Street View, and photos of stores will increase data consumption.
| How to Use Google Maps | Estimated Data Usage | Data Consumption |
|---|---|---|
| Search for a destination | Several hundred KB to several MB per time | Low |
| Zoom in and out of the map | Varies by display range | Low to moderate |
| Use walking navigation | Several MB to a dozen MB per hour | Relatively low |
| Use car navigation | Several MB to several dozen MB per hour | Relatively low |
| View photos of stores and tourist spots | Increases with the number of photos | Moderate |
| Use Street View | Varies greatly by display time | High |
| Display satellite images | Tends to be more than maps | Moderate to high |
For normal map displays and route searches, it is not common to use several hundred MB in a day with just Google Maps.
However, if you frequently open photos of tourist spots or stores, or use Street View for long periods, be careful as data usage will increase.
How many MB do you need per day if using only Google Maps?
When using Google Maps during a trip to Japan, the daily data usage can be estimated as follows, depending on how often you use it.
| Usage Frequency | Estimated Daily Data Usage | Usage Example |
|---|---|---|
| Low | About 20 to 50MB | Searching for routes between the hotel and tourist spots a few times |
| Typical | About 50 to 100MB | Using maps, transfer guides, and walking navigation multiple times |
| High | About 100 to 300MB | Using navigation, photos, and Street View for long periods |
If you are using Google Maps normally, aiming for around 100MB per day will give you some leeway.
However, during your trip to Japan, you will also use other apps such as translation apps, transfer guides, social media, messaging, and web searches.
Therefore, when choosing a travel eSIM, you need to consider not just the data usage for Google Maps, but the overall usage of your smartphone.
Data Capacity Needed for Google Maps by Number of Travel Days
Assuming you use Google Maps for about 50 to 100MB per day, the data usage by the number of travel days is as follows.
| Number of Travel Days | Estimated for Google Maps Only | Recommended Capacity if Using Other Apps |
|---|---|---|
| 3 days | About 150 to 300MB | 1 to 3GB |
| 5 days | About 250 to 500MB | 3 to 5GB |
| 7 days | About 350 to 700MB | 3 to 5GB |
| 10 days | About 500MB to 1GB | 5 to 10GB |
| 14 days | About 700MB to 1.4GB | 5 to 10GB |
| 30 days | About 1.5 to 3GB | 10 to 20GB or more |
If you are using only Google Maps, it is possible to stay within 1GB even for a week-long trip.
However, during your trip, you will also use social media, translation, traffic information, hotel reservation confirmations, and more, so consider the data usage beyond Google Maps.
How many GB do you need for a 3-day trip to Japan?
For a 3-day trip, if you primarily use Google Maps, transfer guides, translation, and messaging, you might manage with around 1GB.
However, if you are viewing photos on social media or watching videos, having around 2 to 3GB would be reassuring.
Who is suited for 1GB?
- Primarily using Google Maps and messaging
- Utilizing hotel or airport Wi-Fi
- Rarely watching videos
- Posting few photos on social media
Who is suited for 3GB?
- Frequently using Google Maps while on the move
- Using social media and web searches

How to Save Data Usage on Google Maps
Download Offline Maps
Google Maps allows you to download maps for areas that are supported in advance.
If you save the areas you plan to visit while connected to Wi-Fi at your hotel, you can reduce the data needed for map loading while out.
However, offline maps may not provide real-time traffic information or some public transportation information.
Search for Destinations Using Hotel Wi-Fi
Before you leave, use the hotel Wi-Fi to search for tourist spots, stations, restaurants, etc.
By saving your destinations, you won't need to search multiple times while out.
Avoid Using Satellite Images
Satellite images typically have more image data than standard maps, which can increase data usage.
If you want to reduce data usage, use the standard map display.
Avoid Long Use of Street View
Street View consumes more data than standard map displays because it continuously loads images.
It is recommended to check in advance using hotel Wi-Fi or similar.
Avoid Excessive Viewing of Photos of Stores or Tourist Spots
Google Maps features many photos of stores and tourist spots.
Displaying photos one after another increases data usage, so check only the necessary photos while using mobile data.
Turn Off Auto-Play for Videos
If videos on social media or websites auto-play, it will consume data outside of Google Maps.
Check the data-saving settings for each app before your trip.
Stop Automatic Photo Backups
Automatically uploading photos to Google Photos or cloud services can generate a lot of data usage.
It is recommended to turn off backups over mobile data and set it to upload only when connected to hotel Wi-Fi.
