In Japan you will use your phone constantly: train connections, maps in busy stations, translation and restaurant bookings. A travel eSIM is a simple alternative to renting a pocket Wi-Fi router or buying a SIM on arrival.
eSIM or pocket Wi-Fi?
- eSIM: nothing to carry, charge or return; works for one phone (and as hotspot if the plan allows it).
- Pocket Wi-Fi: one device for a group, but it must be collected, charged and returned.
How much data?
Navigation and transit apps are used all day in Japan. For one to two weeks, 5–10 GB covers most travellers; plan more for video and social media.
Save your accommodation address in Japanese in your maps app. It makes taxis and navigation much easier.
