Why Get an eSIM for Japan?

As a digital nomad in Japan, reliable mobile data is essential. An eSIM lets you get connected the moment you land, without hunting for a local SIM card shop. Here is why it matters:

Instant activation - Download your eSIM before boarding and activate it when you land, connecting to networks like NTT Docomo.
Keep your home number - No need to swap your physical SIM. Use eSIM for data and keep receiving calls on your main number.
Avoid tourist SIM traps - Airport SIM shops in Japan often overcharge. eSIM plans are transparent and typically cheaper.
Backup connectivity - Japan has great WiFi, but even the best networks drop. Your eSIM keeps you online when cafe WiFi stutters during important calls.
