During your trip to Japan, many people may post their travel experiences on TikTok or watch videos of recommended spots. Therefore, you might be wondering, "How much data does TikTok use?" or "Is a 5GB or 10GB eSIM sufficient?"
Since TikTok is a video-centric app, it tends to use more data compared to apps like Google Maps or transit navigation apps. Particularly, using high-quality videos or live streaming for extended periods can consume a lot of data in a short time.
In this article, we will provide detailed information on the estimated data usage for different TikTok activities, recommend eSIM capacities for your trip to Japan, and explain how to save on data usage.

How much data does TikTok use?
The data usage of TikTok varies significantly based on the time spent watching videos and the video quality. It uses more data than photo-centric social media, and the longer you watch videos, the more data you will consume.
| Activity | Estimated Data Usage |
|---|---|
| Watching videos | High |
| Posting videos | High |
| Watching live streams | Very high |
| Streaming live | Very high |
| Comments & Searches | Low |
Particularly for live streaming and watching high-quality videos, be cautious as they can consume a lot of data even in a short time.

How many GB should you have for a trip to Japan?
The required data capacity greatly depends on how frequently you use TikTok. If you also use other apps like Google Maps or Instagram, consider the overall data usage for your trip when choosing a plan.
| Usage Style | Recommended Capacity |
|---|---|
| Short video watching | 5GB |
| Watching videos daily | 10GB |
| Enjoying video posting | 10GB or more |
| Live streaming & long viewing | Unlimited |
For those who frequently use TikTok, choosing a plan with ample data will allow you to use it without worrying about running out of data during your trip.
How to save on TikTok data usage
- Post videos using Wi-Fi at hotels or cafes
- Avoid long live streaming sessions
- Review video quality settings
- Limit unnecessary auto-play
- Choose an eSIM plan that matches your travel days
Since TikTok is a video-centric service, it tends to use more data than apps like Google Maps or LINE. If you plan to use it frequently during your trip, utilizing Wi-Fi effectively can help save on data usage.
