8 plans for Japan
Buy now, activate later. You have 150 days from purchase to activate, and the plan only starts counting once you do.
Japan still asks every visitor for a disembarkation card, and most airports now take it digitally through the Visit Japan Web portal rather than on paper. Doing it before you fly saves a queue at a kiosk on arrival. Immigration also takes fingerprints and a photograph from every foreign visitor, which has been standard since 2007 and applies whether or not you need a visa.
Whether a Japan plan can be topped up depends on the plan itself, and the details panel on this page says which it is, read live from the catalogue rather than written here. Where top-ups are available you add data to the same eSIM with no new QR code. Where they are not, running out means installing a second eSIM, so it is worth starting one size larger.
Free Wi-Fi is genuinely everywhere here: hotels, every 7-Eleven, FamilyMart and Lawson, and most major stations. A few days of maps and messaging fits in 1 to 3GB. A week of Google Maps, social media and the occasional video sits around 5 to 10GB. Two weeks of heavy use, hotspotting or video calls wants 15 to 20GB.
The eSIM connects to NTT docomo, KDDI, Rakuten Mobile and SoftBank, and your phone moves between them automatically. Signal holds across Tokyo, Osaka, Kyoto and Sapporo, and along the shinkansen between cities, which is where a hotel Wi-Fi plan leaves you stranded.
Buying a physical SIM at Narita or Kansai still works, but it costs 20 to 30 minutes on arrival and usually more money. Install the eSIM at home while you have Wi-Fi, keep your own SIM in the phone for calls, and walk straight to the train with maps already running.
These plans cover Japan as well, so a single eSIM keeps working when you cross the border.

Excellent service, no connection problems in the different places I used it. I think it is the best option in this service.
I have used and tried to use other e-Sims before and while they worked well in one country I couldn't get them to work in another. Wowo is different - it worked like a charm...
I cannot thank the online support enough for the way I was carefully and patiently guided through every step and every option until the solution was arrived at and the Wowo eSim was working...
I used their E sim during my trip to USA and Canada. And in all honesty, it worked perfectly...
Mark is the man. The best support ever. I will recommend wowo to all my friends and relatives.
All good. No issues whatsoever. Customer service helped me with installation. Giving them 5*
