When choosing an eSIM for your trip to Japan, many people may wonder, "How many days can I use 3GB?" "Is 3GB enough for peace of mind during my trip?"
3GB is a popular capacity for short trips, but depending on the apps you use and your travel style, it may or may not be sufficient.
In this article, we will explain in detail how much you can use 3GB during your trip to Japan, the data usage by app, and recommended usage scenarios.
How many days can I use 3GB?
| Usage Style | Usage Estimate |
|---|---|
| Primarily Google Maps and LINE | 2-3 days |
| Using some social media | 1-2 days |
| Watching YouTube | About 3 hours |
| Tethering | Only for a short time |
If you primarily use Google Maps and LINE during your trip, there are cases where you can use 3GB for about 2-3 days. On the other hand, if you frequently watch videos or use social media, you will need more data.
Data Usage by App
| App | Data Usage Estimate |
|---|---|
| Google Maps | About 5-10MB/hour |
| LINE | About 1-5MB/hour |
| About 100-300MB/hour | |
| YouTube (720p) | About 1GB/hour |
| TikTok | About 800MB-1GB/hour |
Since the data usage for Google Maps and LINE is low, it can be sufficient for sightseeing. However, if you watch a lot of videos or browse social media, you need to be cautious.

| Travel Style | Recommendation Level |
|---|---|
| 2-3 day trip | ★★★★★ |
| Primarily using Google Maps | ★★★★★ |
| Primarily using LINE and email | ★★★★★ |
