Why You Need an eSIM for Japan in 2025
Japan is expecting a massive influx of tourists for Expo 2025, set to take place in Osaka, Kansai from April to October 2025. With over 28 million visitors anticipated (according to Japan Times and Expo2025.or.jp), staying connected will be essential for navigation, translation, and communication.
eSIMs provide a convenient and cost-effective way to get mobile data without the hassle of visiting a store or swapping out your SIM card. They’re especially helpful in Japan, where language barriers and complex carrier systems can make buying a local SIM challenging.
What Is an eSIM and How Does It Work?
An eSIM (embedded SIM) is a digital SIM card built into newer smartphones and tablets. Instead of inserting a physical card, you simply download a mobile plan from your chosen provider using a QR code or app.
Devices that support eSIM include:
- iPhone XR and later
- Samsung Galaxy S20 and later
- Google Pixel 3 and newer
- Most newer iPads
For a full list of supported devices, visit Apple or your device manufacturer’s site.
