Staying connected while traveling in Japan has never been easier—thanks to eSIM technology. An eSIM (embedded SIM) is a digital SIM that allows travelers to access mobile data without needing a physical SIM card.

With instant activation and no need for physical pickup, eSIMs provide a reliable alternative to pocket WiFi or traditional SIM cards. However, travelers need to ensure that their phones are both unlocked and eSIM-compatible before purchasing an eSIM.
