A Japan eSim is a great newer option for easy and convenient access to the internet without going through the hassle of finding free wifi hotspots and the associated security concerns. It’s common for your accommodation provider to offer wifi for guests, but once you step outside, you won’t be able to use it anymore.
Access to the internet is even more important as a traveller – uploading photos, using social media, and finding your way around with Google Maps and public transport information are just a few examples of when you will need it. Here’s our article on some of the apps we have found useful when travelling to Japan.
The eSim function is available on all more recent mobile phones – before choosing one of the e Sim Japan options below, check whether your phone is eSim compatible. If you have an older phone which is not eSim compatible, then check out the options to either purchase a Japan sim card or rent a pocket wifi for Japan.
