Travellers on their Japan trip
4.7average ratingThe dog on the confirmation email made me laugh. Small thing but it's why I remembered the brand enough to buy again.
Bought at 7pm, flew at 6am, connected by 10am local. No drama.
Spent two weeks in Spain posting far too many stories and never once thought about data. My old provider would have charged me the price of a flight for that.
Using your eSIM in Japan
Where the connection matters most, what to expect from coverage, and the ten minutes of prep that make the first day easy.
Tokyo, Osaka and Kyoto
Dense coverage everywhere, and you will lean on data constantly for train transfers, IC top ups and restaurant queue apps.
Shinkansen routes
Coverage holds up well along the main lines, with brief drops in the long mountain tunnels.
Hokkaido, the Alps and rural Kyushu
Quieter areas are usually fine on main roads, thinner on mountain routes and in national parks.
What to expect from coverage in Japan
Japan is one of the easiest places in the world to stay connected. Cities, stations and rail corridors are consistently strong.
Live translation, timetable and map apps all need data at the exact moment you cannot ask for wifi, which is why arriving already connected changes the first day completely.
- Install before you fly
Add the eSIM at home so you land connected at Haneda or Narita with no counter queue.
- Set up transit and translation apps first
Do it at home while you still have wifi, so the first train is not the first test.
- Keep your number for bookings
Leave your home SIM on for calls and verification codes, use the eSIM for all data.

Japan eSIM FAQs
How much does an eSIM for Japan cost?
rufly Japan eSIM plans start from €44.99. Every plan includes unlimited data with an honest fair-usage policy, and 10% of your order helps street dogs get fed, treated and housed.
Does the Japan eSIM have unlimited data?
Yes. Every rufly Japan plan is unlimited data with a clear, honest fair-usage policy, so you can map, stream and stay in touch without watching a data counter.
Will my phone work with the Japan eSIM?
The Japan eSIM connects to trusted local networks in Japan, giving you the same coverage a local SIM would. Most phones released from 2019 onward support eSIM, including every iPhone since the XR and most flagship Android phones. You can check yours with our free compatibility checker before you buy.
How do I install my Japan eSIM?
After checkout we email you a QR code. Scan it over wifi before you fly, then switch the eSIM on when you land in Japan and you're connected in seconds, with no airport SIM queues.
When should I activate my Japan eSIM?
Install the eSIM any time before your trip, then turn on data roaming for the eSIM once you arrive in Japan. Your plan validity starts when the eSIM first connects to a local network.
Is an eSIM cheaper than roaming in Japan?
Almost always, yes. Home carriers bill roaming by the day or by the megabyte outside their included zones, and a single trip can cost more than the whole eSIM. A rufly Japan plan is one flat price from €44.99 for unlimited data, so you know the total before you fly and there is no bill waiting when you get home.
Can I share my Japan eSIM with a laptop or another phone?
Yes. Hotspot sharing is included on every rufly plan, with no separate daily hotspot allowance to ration, so a laptop, a tablet or a travel partner can work off the same connection. Only the standard fair-usage policy applies to very heavy sustained use.
Will the Japan eSIM work outside the main cities?
It connects to the same local networks a local SIM would, so coverage in Japan matches what residents get: strong in cities and along main road and rail routes, thinner on mountain roads, remote countryside and long tunnels. Save your maps offline for those stretches and the gaps stop mattering.
Do I keep my own phone number with a Japan eSIM?
Yes. The rufly eSIM sits alongside your normal SIM, so calls and texts still arrive on your usual number while all data runs over the travel plan. You simply leave data roaming off for your home line and on for the eSIM.
What happens when my Japan plan runs out?
The plan just ends. Nothing renews, there is nothing to cancel and no top-up to buy. If your trip is extended, buy another Japan plan and install it the same way, and your original phone number is unaffected throughout.
