Yesim eSIM for travel in Japan
Data for Tokyo and Osaka from $2.20 a day
- €5 bonus for each invited friend
- From $1.10/GB, balance never expires
- 30-day refund on unused plans
Japan plans on the official site begin at $2.20 a day. They cover one country, so pick something broader if the trip continues beyond Japan.
The activation window is generous at 90 days from purchase. Validity only begins when you connect to a Japanese network, so installing at the airport lounge back home costs you no days.
Hotspot is available, which lets a laptop or a companion's phone share the connection. Some plans can be slowed by the carrier's fair usage policy, and the plan page says so.
Top-ups are not offered for this plan type. If your itinerary stretches, buy more days or look at Pay & Fly, which runs from a balance. A referral bonus can cover part of that second purchase.

Does a Japan eSIM come with a number?
No. It is data only, and calls go through internet calling apps.
When should I install it?
Before you leave, at home. The validity period only starts on connecting to a local network.
Can I top up if I run out?
Fixed Japan plans cannot be topped up. Buy another plan or use a Pay & Fly balance.
