Why use an eSIM on your trip to Japan?
In Japan you'll use your phone for almost everything: subway maps, translation, bookings and payments. An eSIM connects you from the moment you land, without renting a pocket Wi-Fi or relying on your carrier's roaming. Check the coverage, validity and data amount of each plan before you buy.
Connected from the airport
Install the eSIM before you travel and activate it when you arrive at Narita, Haneda or Kansai, following your plan's instructions.
No pocket Wi-Fi rental
You don't have to pick up or return a device, and each traveler has their own connection on their phone.

FAQ
Frequently asked questions about the eSIM for Japan
When should I install my eSIM for Japan?
You can install it before you travel with a stable connection. Activation and the start of validity depend on the product, so follow the instructions you receive with your purchase.
Does the eSIM work in Tokyo, Kyoto and Osaka?
Plans use mobile networks available in Japan. Actual coverage and speed depend on the local network, your location, congestion and the product's features.
Which is better: eSIM or pocket Wi-Fi?
An eSIM doesn't require picking up or returning a device or charging another battery. A pocket Wi-Fi can suit groups that always travel together; compare price and convenience for your case.
Can I keep my WhatsApp number?
Yes. Installing a data eSIM does not by itself change the number linked to WhatsApp.
Does the eSIM include a Japanese phone number for calls?
Most travel plans are data-only, unless the product page expressly states otherwise. You can make calls through apps like WhatsApp.
Can I share my connection with other devices?
It depends on the plan. Check whether the product allows hotspot or tethering before you buy.
What if I can't scan the QR code?
Use manual installation if the email includes the required details. If the problem continues, contact support before deleting the eSIM.
Should I get a Japan plan or a regional Asia plan?
A Japan plan is usually enough if you'll only visit that country. For a multi-country trip, compare the coverage and price of a regional Asia plan.
