The (almost) 5-star eSIM
The eSIM was very easy to install and, once I reached my destination, I had a connection from the very first moment without having to worry about roaming.
Activation was quick and simple, and I had a connection the whole time with no hassle. Coverage and speed were very good.
I went on a trip around Latin America and had coverage everywhere, at a very good price. Highly recommended 💪🏼

More about the Japan eSIM
eSIM for Japan: internet without roaming
With a eSIM for Japan you land in Tokyo with mobile data working from minute one, without hunting for a store or wrestling with SIM vending machines at Narita or Haneda airport. Our plans connect to the country's main networks (NTT Docomo and SoftBank, plus coverage from au/KDDI and Rakuten Mobile), which offer real 4G and 5G across virtually the entire archipelago. You install the profile via QR before leaving home and activate it when you arrive. No swapping your physical card, no new numbers, and no surprises on your bill.
Roaming in Japan: why an eSIM makes sense for you
Japan is not part of the European Union, so the "roam like at home" rule doesn't apply. Using your carrier's roaming here usually costs between 10 and 15 € per day, or is even billed per megabyte at sky-high rates. On a two-week trip that's hundreds of euros down the drain. A data eSIM removes that risk: you pay a fixed price and know exactly what you're spending. No need to watch your usage in fear or turn off data every time you leave the hotel.
How much does an eSIM for Japan cost?
You choose the GB based on your travel days. As a guide: for normal use (maps, messaging, social media, and some navigation) figure about 1 GB every 2 or 3 days. For a short getaway to Tokyo and Kyoto, 3 GB is usually enough; for two or three weeks traveling the country, between 5 and 10 GB. If you use Google Maps heavily on the subway or share your connection, go up a tier. You can see all options and other destinations at all destinations.
eSIM vs. physical SIM in Japan
A traditional SIM card forces you to find a point of sale, remove your own card and keep it safe without losing it, and many Japanese tourist SIMs are data-only anyway. The eSIM is a digital profile: it installs in seconds, doesn't take up the slot (so you keep your usual number for SMS and calls from home), and you have it ready before takeoff. Less plastic, less hassle, and zero queues when you land.
Does the eSIM work in Tokyo, Osaka, and Kyoto?
Yes. Coverage on Docomo and SoftBank is excellent in the big cities (Tokyo, Osaka, Kyoto, Yokohama, Nagoya, Sapporo, Fukuoka, and Hiroshima) and also on the Shinkansen bullet train, in Nara, Hakone, or Mount Fuji. You just need an eSIM-compatible, unlocked phone. You'll have internet on the subway, at temples, and right in the middle of Shibuya to translate, get around, and share your trip on the go.
How do you activate the Japan eSIM?
Very simple. After purchase you receive a QR code by email with instructions. Scan it from your phone's settings to install the profile, and when you arrive in Japan activate data roaming on that line. In a few seconds you're connected. If it's your first time, follow our eSIM guide step by step and you'll have it sorted before you pack your bags.
