When choosing between eSIM and Pocket WiFi for your trip to Japan, price is often the deciding factor. At first glance, both options seem affordable — but the real cost depends on how long you stay, how much data you use, and how many people are traveling together.
In this guide, we break down the true cost of eSIM vs Pocket WiFi in Japan, including hidden fees and real-world scenarios, so you can choose the most cost-effective option for your trip.
What Determines the Cost?
Before comparing prices, it’s important to understand what affects the final cost:
- Length of stay
- Daily data usage
- Number of users/devices
- Data speed limits
- Extra fees (delivery, return, damage, extensions)
The cheapest option on paper isn’t always the cheapest in practice.
Typical eSIM Costs in Japan
Most Japan travel eSIM plans are priced by:
- Number of days (e.g. 5, 7, 10, 15 days)
- Daily data limits or total data caps
Average Price Range
- Short-term plans (5–7 days): relatively low cost
- Medium plans (10–20 days): moderate
- Long stays: cost increases quickly due to renewals
What You’re Paying For

Hidden Cost Considerations
