What matters here
Most international visitors reach Kyushu through Fukuoka (FUK). Stops covered on this site include Fukuoka and Beppu, each with its own page below.
Rural stretches have fewer masts than the cities, so a provider that publishes more than one Japanese network gives you a better fallback. Hot-spring inns often have Wi-Fi only in the lobby, which makes your own mobile data more useful than in a city hotel.
Moving between regions does not change anything for a travel eSIM, which works across Japan. What changes is your daily use: long train days mean more maps and timetables.
Download offline maps of the region before leaving, and keep your accommodation addresses saved offline in case you land in a spot with weak signal.
Download offline maps of the areas on your route: they keep working when the signal drops in tunnels or remote valleys.
How much data do you need?
Pick your trip length and how you use your phone. The assumptions are visible and editable.
Install your eSIM in 4 steps
- 1
Buy the plan before you leave and keep the QR code or the app handy.
- 2
Install the eSIM at home on Wi-Fi. Most plans only start the validity period once the eSIM connects in Japan.
- 3
On landing, switch the eSIM on for mobile data and keep your home SIM for calls and texts if you need them.
- 4
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.
Frequently asked questions
Which eSIM is best for Kyushu?
For 10 days with at least 5 GB, Saily ranks first at $10.99. The same eSIM works across Kyushu and the rest of Japan.
Is mobile coverage good in Kyushu?
Cities and main transport corridors are well covered by Japanese networks. Rural stretches have fewer masts than the cities, so a provider that publishes more than one Japanese network gives you a better fallback.
Which network should I choose for rural areas?
Providers that publish more than one Japanese partner network give you a fallback if one is weak. The networks column in the table shows what each provider publishes.
Can I set up the eSIM before leaving home?
Yes, and it is the easiest option: scan the QR code or use the provider’s app on Wi-Fi before departure. Most plans only start counting days when the eSIM first connects in Japan.
eSIM or pocket Wi-Fi for this trip?
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.
Are unlimited plans really unlimited?
Many unlimited plans apply a fair-use rule and slow the speed after a daily threshold. Read the plan conditions on the provider’s page; Airalo currently has the cheapest unlimited option here at $34.50.
How we rank
We compare the plans each provider publishes for Japan. We do not rank on personal testing or user reviews. For each provider we take the cheapest plan that covers the need of this page, then compute a score out of 10:
- Price (50%): cheapest plan on the page ÷ this plan’s price × 10.
- Japanese network (20%): 10 if two or more networks are published, 8 for one, 5 if unknown.
- Hotspot (15%): 10 if tethering is allowed, 0 if not, 5 if unknown.
- Options (15%): app, top-up and an unlimited plan for Japan (10 each if yes, 0 if no, 5 if unknown).
At equal score, providers we have a partner link with are listed first. Prices change often, so check the final price on the provider’s site.
