Comparing Online Purchase vs. Airport Purchase
The biggest difference between buying an eSIM at the airport and purchasing one online is convenience.
When you buy an eSIM at the airport counter, you'll need to stop by the shop after arriving in Japan, which can take some extra time. The process itself is simple, but it's not ideal for travelers who want to connect to the internet immediately after landing.
On the other hand, if you buy an eSIM online before your trip, you can install it in advance and get connected the moment you arrive in Japan--with no need to wait in line or visit a counter. This makes online eSIM purchases the most convenient option for those who want to start using the internet right away after landing at Kansai Airport.
If you're planning to use an eSIM in Japan, it's highly recommended to purchase and set it up online before departure for a smoother travel experience.
Recommended Japan eSIM: eSIM square
The best eSIM for travelers in Japan is eSIM square.
eSIM square offers 24-hour English customer support, so you can travel with confidence knowing help is always available if any issues arise during use. In addition, it includes a recharge feature, allowing you to top up your data anytime if you run out while in Japan.
If you prefer in-person assistance, you can also receive support and explanations at the Telecom Square counter at Kansai Airport.

Recommended Options by Travel Type
For Family or Group Trips
- Pocket Wi-Fi is the best option for family or group travel in Japan. One device can be shared by several people, offering stable internet and great cost performance.
For Solo Travelers
- An eSIM is perfect for solo travel. It's lightweight, easy to activate, and more affordable than a pocket Wi-Fi. You can stay connected anywhere in Japan without carrying extra devices.
For Business Trips
- Pocket Wi-Fi is ideal for business travelers. It allows multiple device connections--such as laptops, tablets, and smartphones-- while providing a fast and stable internet connection for work on the go.
Tips & Precautions
Here are some key points and useful tips to keep in mind for each service.
＜eSIM＞Check if Your Device Is Compatible
eSIMs can only be used on compatible smartphones.
For iPhone users, all models from iPhone XR / XS and newer support eSIM.
For Android users, models such as the Google Pixel 4 and later generally support eSIM, although compatibility may vary depending on the model or country.
Before purchasing an eSIM, make sure your smartphone supports eSIM functionality. This is especially important for Android users, as checking compatibility in advance helps you avoid connection issues during your trip and ensures a smooth internet experience in Japan.
＜SIM Card & eSIM＞About SIM Lock
Before using a SIM card or eSIM, it's important to check whether your smartphone is SIM-locked. In some countries, laws prohibit mobile carriers from locking devices, so you may not need to worry about this. However, if your phone was purchased from a U.S. carrier, there's a good chance it might still be locked -- so make sure to verify its status before your trip.
For iPhone users, you can check the SIM lock status by going to Settings → General → About.
For Android users, the method varies depending on the model and manufacturer, so it's best to refer to your carrier or device manufacturer's official support page.
If you find that your device is SIM-locked, you'll need to either wait until it meets the required number of days for automatic unlocking or submit an unlock request to your carrier. For details on the unlock requirements and procedures of major U.S. carriers, please refer to the guide below.
＜Pocket Wi-Fi＞About Battery Life
When renting a pocket Wi-Fi, it's important to keep an eye on the device's battery level. The more devices you connect at once, the faster the battery will drain. To avoid running out of power during the day, make sure to fully charge your pocket Wi-Fi at your hotel each night. It's also a good idea to carry a portable power bank so you can recharge the device while on the go.
＜All Services＞Be Careful of Data Limits
Whether you're using pocket Wi-Fi, a SIM card, or an eSIM, it's important to monitor your data usage. Even with an "unlimited" plan, some services may reduce speeds if you exceed 3GB of data per day, so if you plan to stream videos or upload large files, choosing a truly unlimited plan is recommended.
Keep in mind that even with a fully unlimited plan, using a large amount of data at once may trigger the Fair Usage Policy implemented by carriers worldwide to ensure fair network usage, which can result in temporary speed restrictions.
