Most visitors reach Beppu through Fukuoka (FUK), or via Oita Airport. From there the usual links are JR Sonic limited express. Install your eSIM before the flight so you can check connections as soon as you land.
Hot-spring inns often have Wi-Fi only in the lobby, which makes your own mobile data more useful than in a city hotel.
Beppu is in the Kyushu region. A single eSIM covers all of Japan, so there is no need for a local plan per city; what varies is how much data you use per day, which you can estimate below.
If you are travelling with several devices, look at the hotspot column before choosing: sharing one plan can be cheaper than buying two.
Keep the QR code or the activation details somewhere you can open offline, in case you need to reinstall the eSIM during the trip.
Pick your trip length and how you use your phone. The assumptions are visible and editable.
Buy the plan before you leave and keep the QR code or the app handy.
Install the eSIM at home on Wi-Fi. Most plans only start the validity period once the eSIM connects in Japan.
On landing, switch the eSIM on for mobile data and keep your home SIM for calls and texts if you need them.
Turn on data roaming for the eSIM line, then check that the phone shows a Japanese network.
Your phone must be carrier-unlocked and eSIM-compatible. Check this in your phone settings before you buy.
For a typical trip of 10 days with at least 5 GB, Saily ranks first at $10.99. The same eSIM works everywhere in Japan, not just in Beppu.
The main arrival airports for Beppu are Fukuoka (FUK). The usual onward links are JR Sonic limited express.
No. Travel eSIMs for Japan are nationwide, so one plan covers every city and region on your route.
Select the eSIM as your mobile data line, turn on data roaming for it, and wait for a Japanese network name to appear. If nothing happens, restart the phone and check the APN settings shown by the provider.
For one or two people with compatible phones, an eSIM is lighter and usually cheaper. A pocket Wi-Fi can suit a large group sharing one connection; our Pocket Wifi vs eSIM guide compares both.
Most travel eSIMs sold for Japan are data only. You can still call through apps such as WhatsApp or FaceTime, and keep your home SIM active for texts.
