🇯🇵 Japan
Japan eSIM for business travel
Business travel to Japan usually means a laptop, a video call from a hotel room and an expectation that connectivity simply works on arrival. Corporate roaming covers that and bills painfully; a local SIM covers it and costs an hour of your first morning.
A prepaid eSIM at $2.80 per GB sits between the two, with hotspot use included so the laptop rides on the same balance.
Reliability where you will actually be
Tokyo, Osaka, Kyoto are covered on NTT Docomo, SoftBank, which are the same tier-one networks the local offices use, with 5G in the business districts.
Constant transit routing, translation and IC card apps. Two weeks often reaches 8 to 12 GB.
Expenses and paperwork
Because the balance is prepaid, the cost is a fixed line on an expense claim rather than a roaming bill that arrives three weeks after the trip. There is no contract to cancel and no per-day fee running in the background while you are back at home.
Buying a local prepaid SIM in Japan means presenting ID and having your details recorded against the number. An eSIM issued outside the country skips that process entirely.

Practical tips
- Budget 1 GB per hour of video calling and turn cameras off when it is not needed
- Tether the laptop rather than trusting hotel wifi for anything sensitive
- Enable auto refill before a heavy travel month so data never stops mid-call
- Keep leftover balance for the next visit to Japan; it does not expire
